Pipsgrowth EX12066 MultiIndicatorConfluence

Pipsgrowth EX12066 is one of the few files in the EX12 family that is built on the standard MQL5 Wizard CExpert class rather than a hand-rolled OnTick event handler. The .mq5 #include list tells the story up front: <Expert\Expert.mqh> for the engine, three signal modules (SignalEnvelopes.mqh, SignalDEMA.mqh, SignalTEMA.mqh) for the voting logic, TrailingParabolicSAR.mqh for stop management, and MoneyFixedLot.mqh for position sizing. The wizard scaffolds the strategy; the user adjusts 26 inputs that parameterize those five building blocks. Every order the EA ever places flows through CExpert.OnTick, which means the framework itself is responsible for tick sequencing, bar detection, and event dispatch — the strategy code in EX12066 only configures weights, thresholds, and trailing/money parameters.

The signal layer is a three-vote weighted consensus. CExpertSignal is constructed in OnInit, then a CSignalEnvelopes filter (filter0), a CSignalDEMA filter (filter1), and a CSignalTEMA filter (filter2) are added to the signal object via signal.AddFilter. Each filter exposes a Weight parameter (Signal_Envelopes_Weight, Signal_DEMA_Weight, Signal_TEMA_Weight — all defaulted to 1.0) and is configured with its own period, applied price, and method. The Envelopes filter uses a 45-period SMA with 0.15 deviation applied to close (1). The DEMA filter uses a 12-period DEMA on close. The TEMA filter uses a 12-period TEMA, and unlike the other two its period is hardcoded to PERIOD_M1 by the line filter2.Period(PERIOD_M1) — TEMA is always sampled on the M1 timeframe regardless of the chart the EA is attached to. Each filter votes bullish, bearish, or neutral with a magnitude in [0..100]; the CExpertSignal sums the weighted votes and compares the running total to the open and close thresholds. Signal_ThresholdOpen defaults to 10 — meaning the combined bullish vote must clear 10 for a long to be permitted. Signal_ThresholdClose defaults to 10 on the close side, so a symmetric bearish-vote magnitude must clear 10 to trigger an exit. Signal_PriceLevel is a price-distance gate in points; Signal_StopLevel (50) and Signal_TakeLevel (50) are passed straight through to the CExpertSignal and become the protective stops for any new position. Signal_Expiration (4) sets how many bars a pending order lives before the framework cancels it.

The three filter weights are the most actionable tuning knob in the EA. Setting Signal_Envelopes_Weight to 0 turns the Envelopes band vote off entirely without removing the indicator; the same is true for DEMA and TEMA. This lets a user collapse the strategy to a single-vote system (Envelopes-only, DEMA-only, TEMA-only) or experiment with asymmetric weighting (Envelopes 0.5 / DEMA 1.0 / TEMA 1.5) to see how the band mean-reversion vote interacts with the trend votes. The framework requires ValidationSettings() to pass in OnInit — that is where CExpert checks the cross-filter parameter constraints before going live.

Trailing is delegated to a single CTrailingPSAR object. The Parabolic SAR is configured with Trailing_ParabolicSAR_Step = 0.02 (the acceleration factor increment) and Trailing_ParabolicSAR_Maximum = 0.2 (the AF ceiling). Once a position is open, the framework watches the SAR flip and moves the stop to the new SAR point on every bar, so a long position's stop ratchets up under the rising SAR dots and a short position's stop ratchets down over the falling SAR dots. The framework takes over the stop on the bar after entry; the EA does not manage the stop in custom code. There is no ATR trailing, no breakeven ratchet, no dynamic profit lock, and no mean-reversion exit in this build — Parabolic SAR is the only trailing mechanism, and Signal_StopLevel / Signal_TakeLevel are the only fixed protective stops the EA ever places.

Position sizing runs through CMoneyFixedLot with Money_FixLot_Percent = 10.0 and Money_FixLot_Lots = 0.1. The FixedLot money manager sends a constant 0.1 lots to every entry, regardless of stop distance, account balance, or symbol contract size. The 10.0 percent field is metadata for CMoneyFixedLot; on this build it is not used to scale the lot. Because the lot is fixed, scaling-in (the SCALING layer mentioned in the architecture comment) is not implemented — every entry is a single 0.1-lot position, and adding to winners is not part of this EA's behavior. The 0.1-lot value, combined with the symmetric 50/50 SL and TP, is the entire money profile the EA enforces on the account.

The event surface in EX12066 is the standard wizard quintet. OnInit instantiates the CExpert, the signal, three filter objects, the trailing, and the money manager, then runs ValidationSettings() and InitIndicators(). OnDeinit calls ExtExpert.Deinit() to release everything. OnTick, OnTrade, and OnTimer each forward to the framework's matching handler. Expert_EveryTick is hardcoded to false, so the framework operates in open-bar mode — entries and trailing re-evaluations only fire on the opening tick of a new bar, not on every quote. This is one of the more important runtime properties: with EveryTick off, backtest behavior is deterministic and identical to live behavior on the same broker, and the EA will not over-trade during a fast M5 candle on a low-liquidity server. The CTrade retry wrappers TryClose_EX12066, TryClosePartial_EX12066, and TryModify_EX12066 sit at the bottom of the file as standalone helpers — they are not called by the framework code (which uses its own CTrade instance inside CExpert) and exist as user-callable utilities for anyone extending the EA with custom OnTick logic.

For practical deployment, EX12066's symmetric 50/50 SL/TP combined with the 0.1 fixed lot makes it a low-volatility targeter — the Envelopes 45/0.15 band is the slow vote, the DEMA 12 is the medium-speed trend vote, the TEMA 12 on M1 is the fast-cycle vote, and Parabolic SAR trailing is the exit engine. On XAUUSD M5, the framework will only enter on a new M5 bar when all three votes are aligned past the threshold; that is rare, so the strategy runs cool and trade counts will be modest. On H1 the same configuration produces a more conservative weekly cadence. The minimum deposit of $100 is enough for a single 0.1-lot XAUUSD position at 50 points of risk because the framework blocks re-entries while a position is still open — pyramiding is not part of this EA's behavior, so the capital requirement is genuinely $100 and not a per-grid estimate.
