Start with Trading basics ↗

Account heat

In Risk Radar development, the calculated money that could be lost from current executable prices to valid stops, compared with balance/equity. Missing stops and unvalued rows are disclosed separately; it is not a maximum-loss guarantee.

Acknowledgement

A response indicating that a request was received or accepted for processing. It is not proof that the requested trade was filled; the reported broker outcome must be checked.

Actual / forecast / previous / revised

For an economic release: actual is the reported result; forecast is an estimate; previous is the earlier period; revised is a later correction. A surprise is a difference from expectations, not a trading instruction.

Armed setup

A prepared plan that you deliberately enable for its supported submission conditions. A saved draft is not armed. Account, symbol, expiry and the labelled build’s rules still apply.

Artificial intelligence (AI)

Software methods used for tasks such as pattern recognition or generating text. The name does not prove accuracy, market foresight or a trading edge. Ask Sentinel currently uses local public-site answers, without a remote model.

Average loss

The total money lost on losing trades divided by the number of losing trades. Usually shown as a positive loss size; state the convention and cost treatment.

Illustrative example: Losses of £20 and £40 give an average loss size of £30.

Read more: Sentinel public learning explanations

Link to this term ↗

Average True Range

Average True Range (ATR) measures recent price-range size, including gaps. ATR(14) uses 14 bars under its stated calculation. It does not predict direction.

Illustrative example: Illustration: a larger ATR describes larger recent ranges, not a more profitable trade.

Backend / adapter

The service and connecting software that relay supported requests and return status between a client and terminal. This is a dependency of web/Android development, not a claim that the desktop customer build sends data to Sentinel.

Read more: MT4 / MT5 and development status

Link to this term ↗

Balance

The account total after recorded deposits, withdrawals, closed trades and other posted entries. It leaves out changing gains and losses on open trades.

Illustrative example: A £1,000 balance with an open trade losing £50 may show £950 equity, assuming no other adjustments.

Link to this term ↗

Branching paths

Different possible next steps depending on which condition is met. In the Playbook prototype these are alternative route options; its simple chart does not yet draw a complete multi-branch route map.

Read more: Playbook Builder prototype scope

Link to this term ↗

Break-even trade

A closed trade with zero net profit or loss after all costs. A stop moved to the entry price is different: fees, financing or slippage can still leave a loss.

Illustrative example: Illustration: a result of 0 before a separate cost of 2 becomes a net loss of 2.

Read more: Sentinel public learning explanations

Link to this term ↗

Breakeven stop adjustment

A rule you configure to move a stop towards entry when its conditions are met. It is not the same as a trade that actually breaks even after costs, and it cannot guarantee no loss.

Read more: Supported management scope

Link to this term ↗

Broker reconciliation

Comparing the request with authoritative orders, deals and positions reported by the connected terminal/broker. An unavailable record remains uncertain; it is not invented as success.

Read more: Sentinel product scope

Link to this term ↗

Broker-aware normalisation

Adjusting the planned volume and levels to the broker’s allowed increments and limits. Review the resulting plan; rounding or constraints can change its size and risk.

Read more: Sentinel product scope

Link to this term ↗

CAPTCHA

A challenge intended to distinguish automated submissions from people. It is not broker-account verification. The public enquiry form may require completing the provider’s challenge.

Read more: Sentinel product scope

Link to this term ↗

Correlation

How movements in two instruments have been related over a measured period. Positive correlation means they tended to move together; negative means oppositely. The relationship can change. Risk Radar development uses a bounded historical sample, not a forecast.

Illustrative example: Two instruments that often fall together may both lose money during the same event.

Read more: Risk Radar development scope

Link to this term ↗

Data processing agreement (DPA)

An agreement setting out how a service processes personal information on another organisation’s behalf. Mentioning it is not confirmation that a particular provider’s terms have been verified; see the privacy notice’s outstanding details.

Read more: ICO: processing agreements

Link to this term ↗

Drawdown

A drop in account value from a stated earlier high to a later value. Check whether the rule measures balance or equity, and how money added or removed is handled.

Illustrative example: With no money added or removed, a fall from £1,000 to £900 is a £100 drawdown, or 10%.

Read more: MetaTrader: drawdown measures

Link to this term ↗

Dry run

A local rehearsal of the configured sequence, showing temporary state and proposed actions without sending live commands. It is not a historical backtest, a broker-connected test or evidence of profitability.

Read more: Playbook Builder prototype scope

Link to this term ↗

Economic calendar

A schedule of economic announcements with their stated times and available reported/estimated values. Times and data can change. News context is information for review, not a signal or a guaranteed market reaction.

Read more: News Intelligence planned integration

Link to this term ↗

Equity

What the account is worth now, including profit or loss on trades that are still open and any other account adjustments.

Illustrative example: With a £1,000 balance and a £50 open loss, equity is £950 if there are no other adjustments.

Read more: Sentinel public learning explanations

Link to this term ↗

Event risk / caution window

The possibility of price jumps, wider spreads or difficult execution around an event. A caution window is a defined period to review that risk, not proof of what the market will do or a universal safe trading time.

Read more: News Intelligence planned integration

Link to this term ↗

Expectancy

The average result per trade across wins, losses and break-even trades. For a completed sample, add all results after costs and divide by the number of trades.

Illustrative example: If ten trades together make £50 after costs, the average result in that sample is £5 per trade.

Expert Advisor (EA)

Software that runs inside MetaTrader and can perform the actions implemented in that build. “EA” does not itself mean trade recommendations or autonomous trade selection. Sentinel’s stated purpose is user-controlled tools.

Read more: MT4 / MT5 and development status

Link to this term ↗

Exposure

The extent to which your positions are affected by market changes. It can be described by position value, direction or money at risk; these are different measures. Risk Radar development shows open/pending exposure and a proposed plan, within its documented scope.

Illustrative example: Two different trades can both lose when the same currency strengthens. Looking at them separately can hide the combined risk.

Read more: Risk Radar development scope

Link to this term ↗

Feature parity

Having the same supported behaviour on two platforms or builds. Similar screenshots or labels do not prove it. Sentinel’s features must be read against each platform’s reference/development status.

Read more: MT4 / MT5 and development status

Link to this term ↗

Financing

A charge or credit for keeping a position past the broker’s daily cut-off, also called rollover. On many trading platforms this appears as swap. It can turn a price gain into an overall loss.

Illustrative example: A £100 gain from the executed prices minus £120 in separate overnight charges leaves a £20 loss, before any other separate fees.

Read more: Sentinel public learning explanations

Link to this term ↗

First-trigger behaviour

Within one Playbook prototype step, the first matching route can be selected and sibling routes cancelled under that step’s mode. Routes in other steps are independent. This is local design/dry-run behaviour, not broker execution.

Read more: Playbook Builder prototype scope

Link to this term ↗

Gross P/L

Profit or loss before the separate costs named in the calculation. Check which costs are already reflected in the prices used.

Illustrative example: If gross profit is £120 and separate fees are £20, net profit is £100.

Read more: Sentinel public learning explanations

Link to this term ↗

Instrument / symbol

The financial product being traded, identified by a platform symbol. Its contract size, price steps and costs must be checked. XAUUSD commonly labels gold priced in US dollars; the exact contract is broker-specific.

Read more: MetaTrader: contract specifications

Link to this term ↗

IP address

A network address used to route internet communications. It can be shared or change over time; it is not a precise identity or location. The privacy notice describes relevant website processing.

Read more: IETF: internet addressing

Link to this term ↗

JavaScript Object Notation (JSON)

A text-based format for saving structured data. Playbook Builder’s separate prototype saves design-time steps, conditions, routes, next-step targets, labels and chart placement. Temporary dry-run state is excluded; a saved file does not execute trades.

Read more: IETF RFC 8259: JSON format

Link to this term ↗

Leverage

Controlling a position whose value is larger than the amount set aside to open it. Gains and losses are driven by the position size, not just that amount.

Illustrative example: If £100 supports a £1,000 position, the position is ten times that amount. This does not mean the loss is limited to £100.

Read more: FCA: leveraged CFD risks

Link to this term ↗

Lifecycle

The sequence of states something passes through. For a chart object this can include creation, changes and archiving; for a trade it includes requests and reported events. It is not a promise of completed integration.

Read more: Sentinel product scope

Link to this term ↗

Management policy

The rules and settings you assign for managing a position, such as stop movement or partial exits. In supported Sentinel development builds the assigned version remains distinct from later changes to chart defaults.

Read more: Supported management scope

Link to this term ↗

Margin

Money required to open or maintain a position. It is not the same as the maximum money you could lose.

Illustrative example: A broker requiring £100 margin does not mean a losing trade must stop at £100.

Read more: MetaTrader: margin calculations

Link to this term ↗

Margin pressure

How current and proposed margin requirements compare with available account resources. Risk Radar development states its account-mode assumptions; the figure is not a guaranteed broker acceptance or a loss limit.

Read more: Risk Radar development scope

Link to this term ↗

MetaTrader / MT4 / MT5

A trading-platform family. MT4 and MT5 are different platforms with different builds and feature scope; they are not interchangeable. Reference or development evidence is not an approved customer release.

Read more: MT4 / MT5 and development status

Link to this term ↗

MQL4 / MQL5

Programming languages for MetaTrader 4 and 5 respectively. Generated source code still needs inspection, compilation and testing for its intended platform; an export is not a qualified trading strategy.

Read more: Sentinel product scope

Link to this term ↗

Net P/L

Profit or loss after costs. Include each cost once; do not subtract a cost again if it is already included in the recorded result.

Illustrative example: A £120 result before costs minus £20 of separate costs leaves £100 net profit.

Read more: Sentinel public learning explanations

Link to this term ↗

Original R

The cash risk recorded at the start of a trade. This fixed amount is the unit called 1R. Moving the stop later does not rewrite it.

Illustrative example: If original risk was £100, a £150 profit after costs is 1.5R. A £100 loss is −1R.

Read more: Sentinel public learning explanations

Link to this term ↗

Partial exit

Closing only part of a position, leaving the remainder exposed to price changes. Sentinel’s step-based MT5 development uses the original volume and a defined remaining portion; broker minimums still apply.

Read more: Supported management scope

Link to this term ↗

Payoff ratio

Average winning-trade profit divided by average losing-trade loss size. It describes payoff size, not how often you win.

Illustrative example: An average £25 win divided by an average £100 loss gives 0.25. Four such wins offset one such loss before any additional costs.

Read more: Sentinel public learning explanations

Link to this term ↗

Planned trade risk

The money your chosen size and exit assumptions put at risk in the calculation. Costs, slippage and gaps can make actual loss larger. Sentinel helps calculate and apply your instructions; it does not choose the trade.

Read more: CME: position size and planned risk

Link to this term ↗

Point

A price unit specified by the instrument and platform. Do not assume that a point and a pip mean the same thing.

Illustrative example: For the five-decimal EUR/USD example, one point is 0.00001 and one pip is 0.00010: ten points per pip. At 100,000 units, that is $1 per point and $10 per pip.

Read more: Sentinel public learning explanations

Link to this term ↗

Position size

How much you buy or sell. A larger size usually means the same price movement gains or loses more money.

Illustrative example: If two otherwise identical positions have sizes one and two, the larger one has twice the price-movement gain or loss before differences in costs.

Read more: Sentinel public learning explanations

Link to this term ↗

Preset / profile

A saved group of settings for later review and selection. Saving it does not place a trade or prove the settings are suitable. A named management policy can have its own revision.

Read more: Sentinel product scope

Link to this term ↗

Profitability

Making more from trading than is lost and paid in costs over the period being measured. Deposits are not trading profit.

Illustrative example: £200 of winning results minus £150 of losing results and £20 of additional costs leaves £30 profit.

Read more: Sentinel public learning explanations

Link to this term ↗

Progressive Web App (PWA)

A website designed to offer some app-like behaviour, such as installation where supported. It is different from a native Android app. Sentinel’s member PWA is a future surface outside the public launch.

Prop challenge / consistency rules

An account-evaluation programme’s stated targets and limits. Daily resets, drawdown basis, qualifying days and consistency definitions vary by provider. Sentinel’s configured monitoring does not certify compliance or guarantee a pass.

Read more: Configured account rules

Link to this term ↗

Protective stop

An instruction intended to close a trade if price reaches a level that limits further loss. The final execution price is not guaranteed.

Illustrative example: If price jumps past your stop level, the trade may close at a worse price than planned.

Link to this term ↗

Provenance

Where information or an image came from, when it was recorded and what it demonstrates. A genuine development screenshot is evidence of visible controls, not proof of every feature or a live trading result.

Read more: Sentinel product scope

Link to this term ↗

Reference / development / planned

A reference build supplies documented development evidence, not a generally available customer release. In development means implementation work exists; planned means intended work without an established working implementation. Read each feature’s platform label.

Read more: MT4 / MT5 and development status

Link to this term ↗

Return on margin

A stated profit/loss divided by the margin used under the stated calculation. It is different from return on account capital. Leverage can make the percentage large while losses remain significant; it is not a future return.

Read more: Trade review development scope

Link to this term ↗

Reward multiple

A completed trade’s profit or loss after costs divided by its original cash risk. It shows the result in units of that starting risk.

Illustrative example: £150 profit after costs ÷ £100 original risk = 1.5R. A £50 loss on the same original risk is −0.5R.

Read more: Sentinel public learning explanations

Link to this term ↗

Risk / reward preview

A comparison between the planned loss to a chosen stop and the planned gain to a chosen target, with stated size and cost assumptions. It is not the realised result or a probability of success.

Read more: CME: position size and planned risk

Link to this term ↗

Risk budget

The largest planned loss you allow for a decision under the assumptions in your plan. Actual losses can exceed a planned amount.

Illustrative example: Before a practice trade, record the amount the plan allows you to risk. Check the size and stop against that amount.

Read more: Sentinel public learning explanations

Link to this term ↗

Rollover

The broker’s daily funding cut-off for an open position. Crossing it can trigger a charge or credit. The number of chargeable days can differ from the number of nights you held the trade.

Illustrative example: A five-minute position crossing a three-charge-day rollover can receive three days of funding. A longer position closed before the cut-off may receive none. Check the instrument’s actual schedule.

Read more: Sentinel public learning explanations

Link to this term ↗

Sample size

How many observations are included in a result. Also check which observations were selected and the period they cover.

Illustrative example: Winning eight of ten trades is an 80% win rate in that sample. Ten trades alone do not establish a dependable future win rate.

Read more: Sentinel public learning explanations

Link to this term ↗

Scenario assumptions

Inputs chosen for a “what if” calculation, such as a price move, cost or correlation. The result depends on those inputs. Risk Radar development uses stated scenarios, not predictions of the next market move.

Read more: Risk Radar development scope

Link to this term ↗

Slippage

The difference between the price you expected and the price at which the trade actually happened. It can help or hurt the result.

Illustrative example: You expected a buy at 100, but it fills at 101. That one-unit difference is slippage.

Read more: Sentinel public learning explanations

Link to this term ↗

Spread

The gap between the price offered to buyers and the price offered to sellers at the same time.

Illustrative example: If you buy at an ask of 101 and immediately sell at an unchanged bid of 100, you lose 1 price unit before separate fees.

Read more: Sentinel public learning explanations

Link to this term ↗

Standard lot

A standardised quantity for a particular instrument. In the EUR/USD example, one standard lot is 100,000 euros. Other products can have different contract sizes.

Illustrative example: Ten standard EUR/USD lots represent 1,000,000 euros. Margin is only the collateral required, not the total size or maximum possible loss.

Read more: Sentinel public learning explanations

Link to this term ↗

Tick

One price update. Tick size is the smallest allowed price step; tick value is its cash value for a stated volume. These are different meanings.

Illustrative example: A new quote is a tick even when the displayed price is unchanged.

Link to this term ↗

Timeframe / parent candle

The time interval represented by each chart bar. M1 represents one minute; H1 one hour. A higher-timeframe or parent candle covers several smaller bars. Time and price source affect comparisons. M15 represents fifteen minutes.

Trade Clearance / preflight

Checks your chosen plan against configured rules and available account information before an entry request. Development outcomes include allowed, caution, reduced-size or blocked with reasons. Passing checks does not predict a profitable trade.

Link to this term ↗

Trading costs

Spread, commissions and any financing or other broker charges. Some costs are already reflected in execution prices; avoid counting them twice when reviewing net results. Check the actual instrument schedule.

Read more: MetaTrader: contract specifications

Link to this term ↗

Trading signal

A suggestion or instruction about which instrument to trade, its direction or timing. Sentinel’s public panel does not choose trades or supply signals. Chart observations and product education are for understanding tools, not trade recommendations.

Read more: Sentinel product scope

Link to this term ↗

Trading terminal

The desktop trading platform connected to the broker account. Sentinel’s public native-panel scope is shown separately for MT4 reference and MT5 development. Forthcoming Android needs its stated backend, computer/VPS, MT4 terminal and EA.

Read more: MT4 / MT5 and development status

Link to this term ↗

Trailing stop

A rule that adjusts a stop as price moves favourably, using the method and distance you select. Native terminal trailing needs the platform running; Sentinel methods and dependencies vary by labelled build. An exact exit price is not guaranteed.

Read more: Supported management scope

Link to this term ↗

Unprotected positions

In Risk Radar development, open trades with a missing/invalid stop or a stop that is not currently loss-limiting. The stop must be below the executable price for a buy and above it for a sell. A valid stop still does not guarantee an exact exit price.

Read more: Risk Radar development scope

Link to this term ↗

Unrealised P/L

The changing profit or loss on a trade that is still open. It has not yet been fixed by closing the trade.

Illustrative example: An open trade showing a £40 loss can still change before it closes. The loss already affects the account’s current value.

Read more: Sentinel public learning explanations

Link to this term ↗

Unvalued exposure

Risk that cannot currently be calculated reliably because required prices or broker cash valuation are unavailable. Risk Radar development labels this separately; missing information is not zero risk.

User interface (UI)

The visible controls and information through which someone uses software. A screenshot can show an interface without demonstrating a working broker connection or every feature.

Virtual private server (VPS)

A rented remote computer that can keep software running. For Android’s described connected workflow it hosts the required backend/terminal software where configured. It does not remove connection, platform or broker dependencies.

Volume profile

A view grouping recorded volume by price level under a stated method. Tick activity is not the same as exchange-traded volume. The source and allocation assumptions matter; it does not reveal every hidden order.

Web cockpit

A browser workspace for viewing connected information and requesting supported actions. It is the interface, not the backend or execution engine. Sentinel’s web cockpit is in development and requires the connected system.

Link to this term ↗

Win rate

The percentage of the trades you counted that finished with a profit. Win rate alone does not determine profitability: the size of wins, losses and costs matters too.

Illustrative example: Eight winning trades out of ten closed trades gives an 80% win rate. That number does not tell you how much money those trades made.

Feature scope

The particular behaviour, platform and build covered by a description. A feature shown in one reference build is not automatically available in another build or to customers.

Broker stop distance

A broker’s minimum permitted distance for certain stop, target or pending-order levels. Restrictions can change; a displayed zero does not always mean every requested level will be accepted.

Broker freeze distance

A broker-defined price range in which certain order changes, cancellations or closes may be restricted. The exact restriction depends on the platform, order and broker conditions.

Using these explanations

These explanations are education and tool information, not signals or personal recommendations. Examples are illustrative, not trading results or forecasts. Order conditions, costs and margin depend on the actual instrument, broker and account.

Sentinel-specific meanings follow documented product scope. MT4 reference, MT5 development and planned labels still apply; a definition does not establish an available or fully integrated feature. Essential explanations are public; member access remains unavailable.

Educational references checked 9 October 2026. SEC order examples concern stocks and CME examples concern futures; check the terms of your actual instrument.
