Pipsgrowth EX12049 MultiIndicatorConfluence

Pipsgrowth EX12049 is built around a two-engine confluence: an inline-calculated Andean Oscillator that breaks every bar into bull and bear power, and a Daily High/Low overlay that replays the prior session's range onto the working chart as constant intraday bands. The pair was chosen so the AOS can fire directional reversals at the moment price rejects one of those bands, and the EA was wired to XAUUSD on M5 because that combination is where the rejection wicks are deepest and the AOS swings are widest.

The AOS engine is fully self-calculated — there is no iCustom handle. On every new bar the function CalculateAndeanOscillator copies g_buffSize (= InpAOSNCheck + InpDHLNCheck + 10 = 360) bars of MqlRates and runs an EMA-style smoothing on the up-leg and down-leg separately. The smoothing factor is the standard alpha = 2.0 / (InpAOSPeriod + 1) = 2/51 with the default InpAOSPeriod = 50, and the leg inputs are max(0, close - prevClose) for up and max(0, prevClose - close) for down. The bull line is upEMA / (upEMA + dnEMA) * 100 and the bear line is dnEMA / (upEMA + dnEMA) * 100, so they are bounded 0-100 and sum to 100. A signal line is then the EMA of the bull line with InpAOSSignalPeriod = 9, applied in reverse through the buffer. A bar where bull crosses up through signal is the trigger event, and a bar where bear crosses up through signal is the mirror trigger for shorts.

The Daily High/Low engine is a single CopyRates call into PERIOD_D1 covering the latest five daily bars. It captures the running today high/low and the finalized previous day high/low, then loops the working M5 buffer, splits each bar's time into a day bucket, and stamps the appropriate high/low onto every bar. The result is two constant lines per day that act as the rejection zones — for the buy arm, the EA wants a bar where the M5 high traded below the daily low while bull power was below bear power; for the sell arm it wants the opposite: an M5 low above the daily high with bull over bear.

The buy signal CheckBuySignal is a three-stage gate. First, the cross on bars [2] and [1] must show bull going from below-or-equal to signal on bar 2 to above signal on bar 1. Second, the function walks backward up to InpAOSNCheck = 300 bars looking for a prior bar j where bull crossed above bear, with three invalidation conditions in the same loop: any bull-under-bear cross, any bull-under-signal cross, or any bull-over-signal cross between the prior cross and the trigger kills the setup. If j stays 0, the function returns false. Third, the function scans from j to j + InpDHLNCheck = 50 for a single bar where iHigh was below g_dailyLow and g_aosBull < g_aosBear. If that bar exists, the buy fires. The sell mirror CheckSellSignal swaps the cross and the dominance conditions symmetrically.

Position construction uses swing extremes for the stop. GetSwingLow walks the last InpSLLookback = 7 bars of iLow and returns the minimum; the buy SL is that minimum minus InpSLDev = 60 points of buffer. GetSwingHigh mirrors that for sells. The TP target is then entry ± 1.5 × the SL distance, set by InpTPCoef = 1.5 — that is the entire risk-to-reward shape of the trade, baked at order entry. If InpReverse is true, the buy function posts a sell with the mirrored SL and TP, and the sell function posts a buy; that flag is the only macro switch between long-only and short-only bias at the signal layer.

ManageTrailingStop runs on every tick before the new-bar gate. It walks PositionsTotal and filters by symbol and magic. For a buy it computes bid - openPrice; once that move clears InpTrailStart = 300 points, it sets newSL = bid - InpTrailDistance = 200 points, but only when newSL is strictly tighter than the current SL and strictly above the open price, so the trailing never loosens and never moves below breakeven. The sell mirror uses ask - openPrice and trails to ask + 200 points. The helper TryModify_EX12049 wraps the modify in a 3-attempt retry that sleeps 100 ms on TRADE_RETCODE_REQUOTE or TRADE_RETCODE_TIMEOUT, so a brief requote does not abort the ratchet. The two closing helpers TryClose_EX12049 and TryClosePartial_EX12049 use the same retry pattern with 200 ms sleeps on REQUOTE, TIMEOUT, PRICE_OFF, and PRICE_CHANGED.

Sizing is set by CalculateLotSize, which prefers a percentage model. With InpRiskPercent = 0.5 the lot is balance * 0.005 / (slPoints * tickValue * point / tickSize), floored to the symbol's lot step, clamped to the symbol min and max, then capped by InpMaxLotSize = 1.0. Setting InpRiskPercent to 0 falls back to InpFixedLot = 0.01 — a deliberately tiny fallback that keeps the EA live on small accounts but forces the user to think before turning on real risk. The SL distance that drives the lot is the actual point gap from ask to swing-derived SL computed inside ExecuteBuy, not a generic input, so every trade sizes against the bar geometry that triggered it.

The no-trade layer is two pieces. IsWithinTradingSession checks the server hour against two optional windows: Session 1 from 8 to 12 and Session 2 from 14 to 18. The default has both enabled, which gives a London morning block, a deliberate one-hour break, and a London/NY afternoon block. Either window being on and matching the current hour is enough to pass. IsSpreadOK measures the live ask/bid gap in points and rejects anything above InpMaxSpread = 200 points (about 2.0 pips on a 5-digit XAUUSD feed). Both gates run before the indicator math on every new bar, so a quiet session costs no CPU past the trailing loop.

Pyramiding is wired but off by default. When InpEnablePyramid flips true, the EA first checks CountOpenTrades against InpMaxPyramidLevels = 3. The IsPyramidSafe helper then walks every open position of the same magic and rejects the new entry if any same-direction position has its SL not pushed at least InpMinSLProfit = 150 points into profit — for a buy that means SL > open + 150pt, for a sell that means SL < open - 150pt, with the sl == 0 case treated as not-in-profit. The result is that you cannot add a second layer until the first layer is genuinely running, which keeps the basket from doubling into a loss.

What to expect in backtest: with the default 0.5% risk on XAUUSD M5, the EA trades the rejection of the prior day's range and tends to cluster entries at the European open and the New York open. The signal is selective on purpose — the AOS cross, the preserved prior cross, and the rejection bar all have to align — so do not be surprised by lower trade counts than a typical indicator EA. The first knobs to tune are InpSLDev (tighter for cleaner breakouts, wider for noisy sessions), InpTPCoef (push above 2.0 only after verifying the rejection-bar geometry actually delivers that extension), and InpMaxSpread (lower it on brokers that widen during the rollover hour). Pyramiding is left off in this default because the AOS rejection setup already wants the position to be the only one on that side.
