Pipsgrowth EX12057 MultiIndicatorConfluence

Pipsgrowth EX12057 is a multi-symbol portfolio EA that runs three independent signal engines — a true Gaussian-smoothed trend filter, a Donchian breakout, and a liquidity-trap detector — and only fires when at least K of a small set of confirmations agree. The header lists EURUSD, GBPUSD, and XAUUSD as the suggested pair set, and the InpSymbolsCSV input accepts up to 20 comma-separated tickers, each of which gets its own state struct (last-bar-traded, last-buy/sell timestamps, loss-streak counters, spread ring buffer, indicator handles). The default signal timeframe is M1 but is mapped from a 1..7 integer that translates to M1/M5/M15/M30/H1/H4/D1 inside OnInit. Capital caps are global: MaxOpenTradesPerSymbol defaults to 3 and MaxTotalOpenTrades defaults to 8, so the EA behaves like a small portfolio of three pairs with a soft cap of twenty-four tickets that the defaults pull down to eight.

The Gaussian engine is implemented as an actual kernel smoother, not a single EMA. BuildGaussianKernel() builds a normalized Gaussian of radius ceil(3*InpGaussianSigma) and length 2r+1 using the closed-form exp(-k²/(2σ²)) weights, and GaussianSmoothed() walks the last r+shift…shift-r closes on the signal timeframe, weights them, and returns the smoothed value. TryEntriesSymbol() reads the smoothed value at shift and shift+1 and takes the difference as a slope: slope>0 is the long regime, slope<0 the short regime. The radius caps at 50 to keep the static-weight buffer at 121 cells. Sigma defaults to 2.0; with the default radius of ceil(3σ)=6, the kernel is 13 cells wide.

The Donchian engine is a 20-period channel on the high/low series (iHighest/iLowest) measured at shift+1, so the breakout test reads close > donHi (long) or close < donLo (short) on the last closed bar. InpDonchianPeriod defaults to 20. The liquidity-trap engine is the most distinctive piece: DetectLiquidityTrapLong() finds the lowest low over the last InpTrapLookbackBars=30 bars (shift+1 onwards) and asks two questions about the current bar at shift — did its low sweep under that range low by at least InpTrapSweepPts=12 points, and did its close re-enter back above the range low by at least InpTrapReentryPts=8 points? A symmetrical DetectLiquidityTrapShort() mirrors the logic against the highest high. Both detectors also call CandleWickCheck(), which verifies the rejection wick is at least InpTrapWickRatio=0.30 of the bar's range, and BarQualityOK(), which enforces a minimum body/range of InpMinBodyToRange=0.18. The three engines are OR'd: long requires slope>0 AND (Donchian up breakout OR liquidity-trap-long), and short is the mirror.

Once a base direction is locked in, the EA runs the confirmation count. CountConfirmations() tallies up to four independent slots: RSI(14) recapture across the 50-line, Bollinger Bands(20, 2.0) re-entry (close back inside from outside the lower/upper band), volume spike ≥1.3× the 20-bar simple average of tick volume, and a higher-timeframe EMA alignment (M30 EMA-200 by default) requiring the close to sit on the right side of the EMA and the EMA slope to point the same way. InpNeedConfirmationsK defaults to 2 and is clamped to [0, ActiveConfirmationSlots()], which is 4 with MTF enabled and 3 without. If both buy and sell base signals fire on the same bar — a real possibility on a doji at the boundary — the EA picks the side with the higher confirmation count; a tie returns no trade, which is a deliberate chop filter.

Risk is sized two ways. InpUseAutoMinLot=true makes every entry use the symbol's SYMBOL_VOLUME_MIN, snapped to SYMBOL_VOLUME_STEP and floored at min and ceiling at max; toggled off, the lot is the InpFixedLot=0.10 default. The send path is the standard 3-fill-mode / 5-retry flow: DetermineAllowedFillings() builds a preference list of IOC > RETURN > FOK from SYMBOL_FILLING_MODE, and SendOrder_AllFillings() walks up to five outer tries, walking the three inner filling modes each time and increasing deviation by 3 points per attempt up to InpMaxAdaptiveDeviation=20. If the broker returns INVALID_STOPS or REQUOTE, the same wrapper retries the entry once with sl=0/tp=0 and then calls ModifyPositionSLTP() to attach the stops on the just-opened ticket.

SL/TP defaults are ATR-based: InpUseATRforSLTP=true, InpATRPeriod=14, InpATR_SL_Mult=3.0, InpATR_TP_Mult=6.0, giving a 1:2 risk-to-reward once you set both multipliers and the per-side CalcSLTP() reads ATR(14) on the signal timeframe at bar 1. Toggle the ATR off and the static fallback is InpSL_Points=250 / InpTP_Points=500. The dynamic lock-profit ratchet, ApplyDynamicLockProfitToPosition(), runs every tick: when bid (or ask) is at least InpLockProfitEveryXPoints=120 points past entry in the favourable direction, the EA floors the moved points, subtracts InpLockMinusYPointsBuffer=18 as a cushion, and tightens the stop to entry + (steps*120 − 18). It never widens — the function returns early if newSL<=curSL — and it respects SYMBOL_TRADE_FREEZE_LEVEL by refusing to push a stop inside the freeze distance of the current bid/ask.

Scaling is a 1-N pyramid, not a grid. The first ticket in a direction is tagged "Initial" in the comment, and every additional ticket in the same direction is tagged "Add#1", "Add#2", etc. with separate per-direction counters g_addCountBuy and g_addCountSell. Adds are gated by AllowOnlyProfitableAdditions=true and MinProfitPerTradeToAdd=4.0, which calls IsAllSameDirProfitableAtLeast() to verify that every existing same-direction ticket on that symbol is at least 4 points in the money before another is allowed. Cooldown adds a per-direction 20-second debounce, InpCooldownSecondsDir=20. The pause-guard pair (PauseOnConsecutiveLosses and PauseOnLossAmount) is OFF by default; when on, the OnTradeTransaction handler listens for DEAL_ENTRY_OUT deals belonging to this magic, sums the deal's profit+swap+commission, increments lossStreakCount on losses, and stacks tradePauseUntil forward using MathMax so a fresh trigger can never shorten an existing pause.

The micro filters worth flagging on a backtest: InpUseDynamicSpreadCap=true builds a 200-tick ring buffer per symbol (MAX_SPREAD_BUF=256) and accepts the trade only if the current spread is at most median + InpSpreadMADMult=3.0 × MAD — an absolute InpSpreadCapAbsPoints ceiling of 0 disables the cap and the median-only path; InpUseBarQualityFilter=true rejects bars where the body is <18% of the range, which kills the worst dojis; InpOneEntryPerBar=true prevents re-entries on the same bar from the timer. Combined, these filters are what make an M1 multi-symbol portfolio tractable — without them, the same Gaussian+Donchian+Trap core would over-fire on noisy ticks.

What to expect in practice. EX12057 is built to spread risk across two or three correlated pairs and let the math of independent signals smooth the equity curve, so a backtest on a single symbol under-represents the design intent. Default config needs an account that allows M1 trading on at least EURUSD and GBPUSD simultaneously with the broker's minimum lot (typically 0.01 on both), so the practical floor is closer to $300-500 than the $100 minDeposit metadata — the metadata reflects the EA's ability to trade a single micro lot, not the recommended multi-symbol starting balance. For a quieter profile, disable the MTF EMA slot by setting InpUseMTFEMA=false (drops the active slots from 4 to 3 and InpNeedConfirmationsK=2 then becomes a stricter 2-of-3 test) and consider widening the Donchian period to 30 or 40 on slower pairs. The Gaussian-Donchian-Trap triplet is the EA's signature; turning any one off (Sigma=0 effectively neutralizes the kernel slope test, InpDonchianPeriod pushed past the bar window disables breakout) materially changes the trade shape.
