Radar Signal EA
- Experts
- Version: 1.59
- Updated: 24 July 2026
RadarSignal EA is a fully automated trading system built around a multi-timeframe Support/Resistance zone engine. Instead of firing market orders on a simple crossover, it maps out real S/R zones across three chained timeframes (e.g. M15 → M30 → H1, or higher, depending on your chart period), waits for price to approach those zones at the right distance — not too early, not too late — and then chooses between a Limit or a Stop order depending on whether the market is ranging or breaking out. Position sizing, breakeven, ATR trailing, and a whipsaw/re-test defense system are all handled automatically, and an optional Grok (xAI) module can be layered on top as a second opinion before any trade is confirmed.
This EA was originally converted from the RadarSignal indicator logic and has been hardened with execution-safety layers (market-closed detection, stop-level checks, filling-mode auto-detection, order-expiry cleanup) to reduce broker-side trade errors.
Key Features
-
3-timeframe weighted bias score — combines ADX, RSI, CCI, OsMA and Williams %R across the current chart timeframe plus the next two higher timeframes into a single weighted directional score.
-
Automatic S/R zone mapping — detects fractal swing clusters, tolerant-merges them using an ATR-scaled tolerance, and keeps only the most relevant zones above/below price.
-
Distance-aware order placement — a zone must be neither too close nor too far (measured in ATR) before the EA considers it tradeable, avoiding both premature entries and chasing price.
-
Adaptive order type — places a Limit order at the zone in range/weak conditions, or a Stop order beyond a confirmed breakout in strong-momentum conditions, with an optional backup retest Limit order.
-
Signal-strength-scaled position sizing — lot size scales with signal strength (Weak / Moderate / Strong) and risk percentage, based on balance, equity, or the lesser of the two.
-
Whipsaw / re-test protection — if price re-enters the entry zone multiple times, the EA automatically de-risks the position with a partial close and tighter SL/TP.
-
Breakeven + ATR trailing stop — moves to breakeven after a configurable R-multiple of profit, then trails using ATR with a minimum step to avoid micro-modifications.
-
Optional Grok AI (xAI) co-pilot — six selectable analysis "personalities" (pure price action, ICT/SMC, fundamental+technical hybrid, scalping, senior combined ICT, quant/risk) can be queried before a trade is confirmed, with an optional hard filter mode.
-
On-chart dashboard — live account balance/equity/floating P&L, current bias score, signal direction and strength, active S/R zone counts, AI status, and open-position summary.
-
Mobile push notifications and detailed Experts-log diagnostics for remote monitoring.
-
Execution-safety layer — auto-detects the broker's best filling mode and expiration type, checks spread/stop-level/market-session before sending any order, and cancels stale pending orders after N bars.
Strengths
-
Structure-based, not indicator-crossover-based. Entries are anchored to actual price structure (S/R zones), which tends to produce more logical stop-loss placement than pure oscillator signals.
-
Built-in trade defense. The re-test/whipsaw de-risking logic is a genuinely useful feature most retail EAs lack — it reacts to price chopping back into a zone rather than letting a losing idea run at full size.
-
Configurable aggressiveness. Score thresholds, lot multipliers per strength category, and ATR distance filters let a user tune the EA from conservative to more active without touching code.
-
Transparent decision-making. The on-chart dashboard and verbose logging show exactly why the EA did or didn't trade on any given bar (spread too wide, session closed, zone too far, etc.), which shortens debugging time considerably.
-
AI layer is optional and modular. Traders who don't want to depend on an external API can run the EA purely on its own multi-timeframe logic; the Grok integration is opt-in.
-
Broker-compatibility handling. Filling-mode and expiration-mode are detected automatically rather than hard-coded, reducing "Invalid Fill" / "Invalid Expiration" rejection errors across different brokers.
Considerations / Limitations
-
Optional AI module requires a third-party API key and internet dependency. InpUseAIAnalysis relies on an external xAI/Grok endpoint — this adds latency, a recurring API cost, and an external point of failure. If the AI filter (InpAIFilterTrade) is enabled and the API call fails or times out, that trade opportunity may be skipped entirely.
-
Zone-based entries mean the EA doesn't always trade every bar. With a strict score threshold and ATR distance window, the EA can go through quiet periods with no valid setup — this is by design, but it is not a "high-frequency" system.
-
Backtest quality depends on broker tick/spread data. Because entries are highly sensitive to spread (InpMaxSpreadPips) and ATR-based zone distances, results will vary noticeably between brokers with different average spreads and between real-tick vs. generated-tick backtests.
-
Multi-symbol/multi-timeframe indicator load. The EA opens indicator handles on three timeframes simultaneously (ADX, RSI, CCI, OsMA, WPR, ATR); on very low-spec VPS setups with many charts running in parallel this adds some overhead.
-
No built-in news filter. Trading-hours filtering (InpUseTimeFilter) is time-of-day only — there is no economic-calendar avoidance, so high-impact news spikes can still trigger breakout-style Stop entries.
-
Like any automated strategy, past performance and backtests are not a guarantee of future results. Users should forward-test on a demo account and understand the risk settings before running the EA lives
Input Parameters Explained
General
| Parameter | Description |
| InpMagic | Unique magic number used to identify and manage this EA's own orders/positions. |
| InpComment | Comment tag attached to every order sent by the EA. |
| InpMaxSlippagePips | Maximum allowed slippage/deviation (in pips) on market execution. |
| InpVerboseLogging | Prints detailed step-by-step decision logs to the Experts tab — useful for diagnostics. |
Signal Engine (multi-timeframe bias score)
| Parameter | Description |
| InpReverseSignal | Inverts the final Buy/Sell direction — useful for testing contrarian variants. |
| InpADXPeriod / InpADXTrendLevel | ADX period and the minimum ADX value considered "trending" (adds directional weight to the score only when trending). |
| InpRSIPeriod | RSI period; score is +1 if RSI > 50, else −1. |
| InpCCIPeriod | CCI period; score is +1 if CCI > 0, else −1. |
| InpWPRPeriod | Williams %R period; score is +1 if WPR > −50, else −1. |
| InpOsMAFast / InpOsMASlow / InpOsMASignal | MACD-OsMA settings; score is +1 if the OsMA histogram is positive, else −1. |
| InpScoreThreshold | Minimum absolute weighted score required before the EA considers a directional bias valid. |
| InpWeakThreshold / InpStrongThreshold | Score magnitude cut-offs that classify the signal as Weak/Moderate/Strong (used for lot sizing). |
How the score works: each of the 5 indicators contributes ±1 per timeframe, are summed per timeframe, and the 3 timeframes are combined with weights 1 / 2 / 3 (current chart timeframe weighted least, the highest timeframe weighted most).
Filters & Execution Protection
| Parameter | Description |

| InpGrokTimeoutMs | Timeout for the API request. |
| InpAIFilterTrade | When enabled, a trade is only sent if Grok's analysis confirms the EA's own signal. |

Order Placement / Timing
| Parameter | Description |

| InpBreakevenBufferPips | Buffer added beyond entry when the whipsaw logic moves SL to breakeven. |
Recommended Use
-
Best suited to traders who want a structure-driven, semi-discretionary-feeling automated system rather than a pure scalper or grid/martingale EA.
-
Start on a demo account to observe the dashboard, confirm zone detection matches your own chart reading, and tune InpScoreThreshold, InpMaxSpreadPips, and the ATR distance filters to your broker's typical conditions.
-
The Grok AI module is optional — test the EA with InpUseAIAnalysis = false first to understand the baseline logic before layering AI confirmation on top.
-
As with any automated trading tool, use appropriate risk percentage settings and never risk capital you cannot afford to lose. Past performance shown in backtests or live results does not guarantee future performance.
