Pipsgrowth EX18091 TrendFollow

EX18091 is a three-strategy composite that runs three independent signal engines in parallel on a single XAUUSD chart, each owning its own magic number so the strategies cannot interfere with each other inside the terminal. The three engines are RSI Follow (magic 22218091), RSI Reverse (magic 22218092) and EMA Cross (magic 22218093). Every entry, every exit and every state flag is partitioned by magic, so you can run any subset you like — one, two or all three — by toggling the three InpEnable… switches on the inputs panel.

The RSI Follow engine is a classical mean-reversion-through-trend signal. It watches a 49-period RSI applied to close on the trading timeframe. When RSI[1] pushes above the 81 overbought line, a rsiOverbought state flag is latched. The flag is consumed — and a sell is fired at the next bar — only when RSI[1] drops below the 48 exit level and RSI[1] is lower than RSI[0] (an actual turn, not a flat). The mirror logic fires buys when RSI[1] drops below 41, then crosses back above 48 with RSI[1] > RSI[0]. The signal is latched, not a one-tick observation, which is what stops the engine from whipsawing on a single oversold bar. Sessions are pinned: this engine is awake between server hours 24:00 and 08:00 — the Asian session, where XAUUSD often stages its reversals off the prior New York close.

The RSI Reverse engine runs on a 159-period RSI, a much longer window that filters for genuinely stretched conditions rather than intraday noise. The 51/49 OB/OS bands sit closer to the 50 mid-line, so the engine is looking for RSI to push past neutral and then re-cross a 54 trigger line on the way back. Buy is triggered when RSI was oversold (below 49) and re-crosses above 54; sell is the mirror. This engine is awake between 12:00 and 22:00 server time — the London and New York overlap, when XAUUSD trends hard and the long-period RSI gives cleaner reversals. Two extra layers discipline it: a configurable cooldown (InpRSIReverseCooldownBars = 11 bars) that fires after a close, and a InpRSIReverseCooldownOnLoss flag that limits the cooldown to losing closes only. The IsRSIReverseInCooldown() function checks the bar clock against rsiReverseLastCloseTime + cooldownBars * PeriodSeconds(g_InpTimeframe) and refuses to fire while the gate is on.

The EMA Cross engine is the third pillar. It reads a 175-period EMA on close and looks for the close to cross the EMA on the most recent bar (ema[1] < close[1] && ema[0] > close[0] for buy, mirror for sell). When the distance filter is on (InpUseEMADistanceEntry = true, default), the cross alone is not enough — the engine requires that price has stayed beyond the EMA by at least 8,440 points for InpEMADistancePeriod = 30 consecutive bars. That is a 30-bar separation check: it filters out cross signals that come back inside the EMA immediately, keeping only the ones where the cross is the start of a sustained excursion. When the distance filter is off, the cross alone is sufficient. The signal is latched in emaCrossBuySignal / emaCrossSellSignal and aged out after InpEMADistancePeriod * 2 bars so the engine cannot queue an entry that fires days later. EMA Cross is awake 22:00 to 12:00 server time, the same Asian-through-London-open window that pairs with the RSI Follow Asian window without overlap.

The strategy-lock feature ties the three engines together. When InpEnableStrategyLock = true and any strategy (other than the one currently evaluating) has a profitable position with profit > InpLockProfitThreshold = 120 points, the engine under evaluation is suppressed — it returns without firing. That is the EA's defence against the three engines trading the same instrument in conflicting directions simultaneously. Optionally InpCloseOppositeTrades = true extends the lock into an enforcement: when one strategy's open position is in profit, the EA actively closes the opposing strategy's open trade. On XAUUSD that converts the multi-strategy set-up from a pure signal-fan-out into a triage — one engine at a time is the active book.

Exits mirror the entry logic and are partitioned by magic. For RSI Follow, a buy is closed when RSI[0] drops below the 48 exit level; a sell is closed when RSI[0] rises above 48. For RSI Reverse, the same idea on the 159-period RSI around the 49 exit level. For EMA Cross, the exit fires when the close crosses back through the EMA in the direction opposite the trade — a buy is closed the moment close dips below the EMA, a sell the moment close rises above. None of the three engines places a fixed stop-loss or take-profit at the open; the 0, 0, 0 bracket on every trade.Buy and trade.Sell call means the only exits are the indicator-driven reversals and the optional InpEnableStrategyLock cross-engine cleanup. That keeps the trade lifecycle entirely indicator-defined, but it also means the EA relies on the exit signals firing — if a session window closes and the engine is shut off, an open position can sit until the next session reopens the matching state flag. Toggle InpRSIFollowCloseOutsideHours, InpRSIReverseCloseOutsideHours or InpEMACrossCloseOutsideHours to force-close positions when the session ends.

Sizing is intentionally simple. Every entry uses the single InpLotSize = 0.01 input, with no risk-percentage formula, no compounding multiplier and no balance cap. On a $100 minimum-deposit account that gives ten concurrent micro-lot positions if all three engines fire the same bar, which on a calm XAUUSD day is plausible but on a London-open breakout is unlikely because the strategy-lock will suppress the late entries. Slippage is fixed at 10 points via trade.SetDeviationInPoints(10), and filling mode is delegated to the broker via trade.SetTypeFillingBySymbol(_Symbol). Position retries are exposed — TryClose_EX18091 and TryModify_EX18091 each loop three times on REQUOTE, TIMEOUT, PRICE_OFF and PRICE_CHANGED responses, sleeping 200 ms (close) or 100 ms (modify) between attempts — so an unstable connection around the New York close will not silently drop an exit.

A few details that matter in production. First, the entire signal stack runs only on a new bar (IsNewBar() gates OnTick()), so on a quiet session you can sit through dozens of ticks with no recompute and no slippage risk. Second, the timeframe is set by the InpTimeframe enum-style input (1 = M1 through 7 = D1, default 0 = H1) — all three engines read indicators on the same timeframe, so if you want a faster RSI Follow on M5 and a slower EMA Cross on H1, you need to split the EA across two charts. Third, the magic numbers are independent inputs (InpMagicNumberRSIFollow, InpMagicNumberRSIReverse, InpMagicNumberEMACross), so if you are running other EAs on the same XAUUSD terminal you can renumber to avoid collisions. Finally, because the EA places no SL or TP at open, the broker-side stop-out level is the only hard floor on any individual position — the EA's whole risk control is the indicator-driven exit, the strategy-lock inhibit, and the optional session-close shutdown. Test on demo for at least a quarter before treating the signals as proven, and prefer brokers that let you set 0/0 brackets cleanly on micro-lot gold.
