FoxterAI — Grid Trading EA with ATR-Adaptive Step and Interactive Control Panel
FoxterAI is an automated grid trading robot for MetaTrader 5 built on an averaging grid strategy. The grid step is calculated from the ATR indicator rather than a fixed pip value: during high volatility orders are placed wider, during low volatility — closer together. The EA manages two independent series simultaneously — BUY and SELL.
Key Feature: Control Panel Fully Works Inside the Strategy Tester
The built-in interactive panel is fully functional in the Strategy Tester visual mode. During a backtest you can change key parameters without stopping the test: enable/disable trading, switch direction, change entry mode, activate Basket Mode, adjust profit target, enable the Level System, change grid limits — and immediately see the effect on results. This dramatically speeds up optimization.
Architecture
On every tick the EA executes: series update, DetectTrend(), CheckNewSeriesEntry(), ManagePositions() (breakeven, trailing, grid averaging, Take Profit), panel update.
Trend Detection
Custom ATR algorithm — average High-Low range over N completed bars on the selected timeframe. ATR is cached and recalculated only on new candle formation.
- TrendTimeframe — timeframe for trend detection (H1)
- TrendATR_Period — ATR period in bars (14)
SuperTrend
Built-in calculation without external indicators. Base = (High+Low)/2, Upper = Base + Mult x ATR, Lower = Base - Mult x ATR. Used as entry filter, averaging filter, and level source. SuperTrend line is drawn directly on the chart.
- SuperTrendTF — SuperTrend timeframe (H1)
- SuperTrendATRPeriod — ATR period (10)
- SuperTrendMultiplier — ATR multiplier (3.0)
- DrawSuperTrend — draw line on chart (true)
- SuperTrendBarsToDraw — bars to draw (300)
Entry Modes
Cycled through via the Entry Mode button on the panel. Four modes available:
- Trend only — enters in the direction of the trend
- Trend + Impulse (default) — additionally requires an impulse candle on M15 whose range exceeds the specified % of ATR
- Trend + Impulse + SuperTrend — maximum filtering: trend, impulse, and SuperTrend simultaneously
- Trend + SuperTrend — trend confirmed by SuperTrend, no impulse required
- EntryMode — entry mode (Trend + Impulse)
- ImpulseTimeframe — timeframe for impulse detection (M15)
- ImpulseATR_Period — ATR period for impulse (14)
- ImpulseMinPercent — minimum impulse size % of ATR (150)
- MinBarsBetweenSeries — bars between close and new entry (1)
Averaging Grid
Step = ATR(Grid_Timeframe, Grid_ATR_Period) x Grid_StepPercent / 100. Averaging triggers when all conditions are met: price moved one step from the last order, trend matches the series direction, minimum time interval passed, order count and total lot within limits.
- Grid_Timeframe — timeframe for step calculation (M15)
- Grid_ATR_Period — ATR period for step (14)
- Grid_StepPercent — grid step % of ATR (50)
- MartinCoeff — martingale multiplier (1.5)
- FirstLotMultiplier — first lot multiplier (1.0)
- MaxOrdersBuy / MaxOrdersSell — max orders per series (10)
- MaxTotalLot — max total lot per series (2.0)
- GridIntervalMinutes — minimum interval between averaging orders min (30)
- UseSTForAveraging — SuperTrend filter for averaging (false)
Advanced Grid and Martingale Modes
Expanding grid (UseExpandingGrid): each grid step is multiplied by GridStepMultiplier. Reduces averaging frequency during deep moves against the position.
Stepped martingale (UseSteppedMartin): divides the grid into three zones with different multipliers. Example: first 3 orders at 1.0, next 3 at 1.3, all subsequent at 1.6. Activates martingale only deep in the grid.
ATR-adaptive martingale (UseATRAdaptiveMartin): dynamically adjusts the multiplier based on current volatility. High volatility — minimum coefficient, low volatility — maximum. All three modes can be combined.
- UseExpandingGrid — expanding grid (false), GridStepMultiplier — step multiplier (1.3)
- UseSteppedMartin — stepped martingale (false)
- StepZone1Count / Coeff — zone 1: order count and multiplier (3 / 1.0)
- StepZone2Count / Coeff — zone 2 (3 / 1.3), StepZone3Coeff — zone 3 (1.6)
- UseATRAdaptiveMartin — ATR-adaptive martingale (false)
- ATRAdaptive_MinCoeff — min coefficient at high volatility (1.0)
- ATRAdaptive_MaxCoeff — max coefficient at low volatility (2.0)
Take Profit Modes
ATR-based TP: distance = ATR(TP_Timeframe, TP_ATR_Period) x TP_Percent / 100.
Deposit % TP: target = Balance x FirstTPDepositPercent / 100.
Individual TP: fixed TP per order in points (Basket Mode only, 0 = disabled).
Combined series TP: when 2+ orders exist, TP is recalculated from the weighted average open price. When IncludeCommissionSwap is enabled, accumulated commissions and swap are deducted.
- TP_Timeframe — ATR TP timeframe (M15), TP_ATR_Period — period (14)
- TP_Percent — TP size % of ATR (100)
- UseDepositPercentTP — deposit % TP (false)
- FirstTPDepositPercent — first order TP % of balance (0.5)
- IndividualTP_Points — individual TP in points (100, 0=disabled)
- IncludeCommissionSwap — include commission and swap in P&L (true)
- SlippagePercent — slippage compensation % of profit (0.1)
Basket
Combines BUY and SELL series for joint closing at a shared profit target. Three types:
- OFF — series managed independently
- Immediate — combined from the first order
- After N — combined after N averaging orders
Basket Mode: extended profit management — includes not only open but also already closed orders of the current grid. Allows accumulating profit from partial closings.
- BasketType — type: OFF / Immediate / After N (OFF)
- BasketProfitPercent — target profit % of balance (0.1)
- BasketAfterNOrders — combine after N averagings (5)
- UseBasketMode — Basket Mode (false)
Breakeven and Trailing
Breakeven activates when the series has 2+ orders. When price reaches the specified distance, SL is moved to the open price (or offset from it).
- UseBreakeven — enable breakeven (false)
- BreakevenActivatePoints — points to activate (100)
- BreakevenSL_Points — SL offset from open price (0 = at open price)
Trailing works only on the first order (no averaging). Disabled automatically when the second order appears. Distances are set as % of ATR.
- UseFirstOrderTrailing — enable trailing (false)
- TrailActivatePercent — activation threshold % of ATR (70)
- TrailDistancePercent — trailing distance % of ATR (50)
Level System
Optional module for anchoring grid logic to significant price levels. Enabled via the Levels button on the panel.
Three level sources (Source button):
- Round levels — levels at a fixed pip step (e.g. every 50 points). 21 levels around current price
- Daily High/Low — High/Low levels over N bars on two timeframes. Default: D1x1 + W1x1 = 4 levels
- SuperTrend TF — SuperTrend boundary on the LevelTF timeframe
Four operating modes (Mode button):
- Filter — levels displayed, no effect on trading
- TP at levels — TP is set at the nearest level in trade direction
- Entry only — first order opens only near a level (LevelEntryZone x ATR)
- Full — TP at levels + entry near level + grid step adapted to next level
- UseLevelAveraging — enable system (false), LevelSource — Round/D-HL/ST-TF
- RoundLevelStep — round level step points (50), LevelTF — timeframe (H4)
- LevelHL_TF1/Count1 — D-HL pair 1 (D1/1), LevelHL_TF2/Count2 — pair 2 (W1/1)
- UseLevelTP — TP at levels (false), LevelTP_OffsetPips — offset points (5)
- UseLevelEntry — entry near level only (false), LevelEntryZone — zone ATR fraction (0.15)
- UseLevelGrid — adaptive grid step (false), UseLevelAutoLot — auto lot (false)
Losing Order Trim
Forcibly closes the most losing order in the series when the remaining orders still allow reaching the profit target. Trim button on the panel.
- OFF — disabled
- Own — closes if the remaining orders of the same direction yield target profit
- Joint — closes if all remaining BUY and SELL orders together yield target profit
Filters and Protection
- Spread filter: current spread must not exceed MaxSpread points (30)
- Margin filter: free margin level must be at least MinFreeMarginLevel % (200)
- Time windows: up to three independent windows "09:00-17:00". Midnight crossing supported. If all empty — 24/7 trading
- ATR protection: if ATR = 0 (no history loaded) — all trading is blocked
- Symbol normalization (UseNormalizeSymbol): removes broker suffixes (EURUSDm to EURUSD)

Risk Notice
Grid trading involves holding multiple open positions simultaneously. During strong directional moves, drawdown can be significant. Before using on a live account, thoroughly test all settings in the Strategy Tester and select risk management parameters (initial lot, max orders, max total lot) appropriate to your account size.
