Pipsgrowth EX17004 Volatility

Pipsgrowth EX17004 is a lightweight adaptive volatility scalper whose signal is a single, repeatable rule: was the last bar on the chosen timeframe bullish or bearish. With zero external indicator handles attached at OnInit — the EA is unusual in this respect within the PipsGrowth family — every entry decision reduces to whether iClose is above or below iOpen on the main timeframe. The strategy compensates for that minimalism with a comparatively rich position-management layer: a per-direction trade cap, a hard per-trade stop, a breakeven ratchet, a fixed-distance trailing stop, a multi-tier dynamic profit lock, and a 20 percent account drawdown circuit breaker. The header advertises a 12-layer architecture (REGIME, SIGNAL, ENTRY, CONFIRM, NO-TRADE, CAPITAL CAP, RISK, SIZING, MANAGE, EXIT, SCALING, OnTester) and in this implementation the heavy lifting lives in the MANAGE and EXIT bands rather than in SIGNAL.

The signal path is short. On every tick, OnTick calls ManageAllPositions first, then AreGlobalTradingConditionsMet to validate session, drawdown and spread, then reads iOpen and iClose for the bar at shift 0 of g_Main_Timeframe (default H1, configurable via Main_Timeframe to M1, M5, M15, M30, H4, or D1). It then counts current BUY and SELL tickets with CountOpenBuyTrades and CountOpenSellTrades, runs the base condition check in CheckBaseConditionsForNewTrade (which enforces OneTradeOnly, MaxOpenTradesInBothDirections, and AllowOnlyProfitableAdditions), and finally calls TryOpenBuy and TryOpenSell in the same tick. The primary trigger in IsPrimaryBuyTrigger returns true when c0_close > c0_open; the mirror in IsPrimarySellTrigger returns true when c0_close < c0_open. Those two checks are the only signal in the EA.

Confirmation is wired in but currently minimal. IsInitialBuyConfirmMet and IsInitialSellConfirmMet branch on the ConfirmationLogicType input. In CONFIRM_ALL_ACTIVE_AGREE mode the EA calls AllActiveBuyConfirmations, which in turn calls only CandleDirection_BuyConfirm — itself a re-check of close > open. In CONFIRM_WEIGHTED_SCORE mode the EA accumulates a 0/1 score and demands 70 percent agreement via WeightedBuyConfirmation. Because only one confirmation source is wired up, both modes are effectively equivalent in current operation: the trigger and the confirmation collapse to the same candle check. The // Extend: Add more indicator logic here as needed comments next to each confirmation function make the intended extension path explicit. If a future build adds MACD or RSI passes to those confirm functions, the same scaffolding will weight them into the score.

The capital-cap layer is where EX17004 differs from a typical single-shot scalper. The EA exposes three independent limits: MaxBuyTrades = 3, MaxSellTrades = 3, and MaxOpenTradesInBothDirections = 5. The combination means a basket can hold up to three longs and three shorts simultaneously, but no more than five tickets in total, and OneTradeOnly collapses the basket to a single position when set true. The addition path is conditional: when AllowOnlyProfitableAdditions = true (the default), AllPositionsHaveMinProfitInPoints runs across every open position and requires each one to be at least MinProfitPerTradeToAdd_Points = 180 in profit before a new ticket in any direction is allowed. A MinTimeBetweenTrades_Seconds = 30 throttle further prevents the EA from stacking orders within half a minute of one another in the same direction. Together those rules mean a trade in the same direction as a losing basket is blocked — the EA only scales into a direction whose existing tickets are at least 180 points in the green.

The risk layer is anchored on a single number. HardSL_Points = 120 is reused as the per-trade stop, the breakeven trigger distance, and the trailing stop distance. The breakeven in ManageBreakeven waits for price to reach openPrice + 120 * _Point, then moves the stop to openPrice + 1 * _Point (one point above entry). The trailing in ManageTrailingStop keeps a constant 120-point distance behind the current bid or ask and only ratchets forward, never back. MaxDrawdownPercent = 20.0 acts as the circuit breaker: when the equity falls more than 20 percent below the recorded balance, CheckMaxDrawdown returns false and no new entries are taken. A MaxAllowedSpreadPoints = 25 filter rejects entries when the spread on the active symbol exceeds 25 points, and MaxSlippagePoints = 5 is forwarded to the CTrade object for market orders.

The exit layer adds the dynamic profit lock. When EnableDynamicLockProfit = true, ManageDynamicLockProfit divides the current profit in points by LockProfitEvery_X_Points = 150, and for every complete multiple moves the stop to openPrice ± (multiple * 150 - 20) * _Point. The LockMinus_Y_Points_Buffer = 20 keeps a 20-point cushion so the lock sits a little below the locked-in profit, leaving room for spread on the way out. The lock is monotone: it only ever raises the stop on a long, only ever lowers it on a short. With the defaults, a 200-point profit locks 130 points, a 300-point profit locks 280, a 450-point profit locks 430, and so on, in 150-point steps.

The no-trade layer is a four-session filter. EnableSessionFilter is off by default, but when enabled IsTradingSessionActive walks Asian (00:00-08:00 server), London (08:00-16:00), New York (13:00-21:00), and a custom block through CheckSingleSession, which supports overnight windows that cross midnight. All four are configurable to the minute. A trader who wants to restrict EX17004 to a specific kill zone can disable the three built-in sessions and rely solely on the custom slot.

The retry scaffold at the bottom of the file — TryClose_EX17004, TryClosePartial_EX17004, and TryModify_EX17004 — wraps the CTrade API in a three-attempt loop with 200 ms (or 100 ms for modify) back-off after TRADE_RETCODE_REQUOTE, TRADE_RETCODE_TIMEOUT, TRADE_RETCODE_PRICE_OFF, or TRADE_RETCODE_PRICE_CHANGED. These helpers are present for completeness even though the current signal path doesn't invoke partial closes; they protect any future exit-and-replace logic against requotes. The trade comment is set to Psgrowth.com Expert_17004 and the magic is the standard 222 + expert ID = 22217004.

A practical note on backtesting. Because the entry signal is identical to the confirmation signal, the EA's hit rate tracks the bar-by-bar direction of the chosen timeframe. On H1 XAUUSD the trades are sparse; on M5 they cluster heavily. The dynamic profit lock tends to convert a higher proportion of trades into small scratches on gold, where 150-point swings inside a single 5-minute bar are common. The MaxAllowedSpreadPoints = 25 should be tightened on ECN accounts where typical XAUUSD spread is 10-15 points, since a 25-point ceiling will let almost anything through. The 20 percent drawdown circuit breaker is the dominant risk control and should not be raised without proportional capital backing. Net-net, EX17004 is a transparent, parameter-light scalper that the trader is meant to extend with their own indicator logic into the empty confirmation slots.
