Pipsgrowth EX14009 Scalper

The EX14009 Forex Fraus M1 sits at the minimalist end of the PipsGrowth scalper family. Where most EX14 cousins run an indicator stack, a regime router, and a multi-stage exit pipeline, this one watches a single Williams Percent Range reading on the M1 bar and acts only at the most extreme tails of its distribution. The whole decision tree on a new bar reduces to three lines: read WPR[0], compare it to -99.9 and -0.1, and either open a buy, open a sell, or do nothing. That focus is the design.

Williams Percent Range is a momentum oscillator bound between 0 and -100. Values near 0 mean the close printed near the high of the lookback window; values near -100 mean it printed near the low. A standard 14-period WPR is noisy and fires constantly on M1. The strategy instead samples WPR over an unusually long 360-bar window — six hours of M1 bars — which dampens the oscillator into a slow-moving envelope. On that smoothed curve, reaching below -99.9 is genuinely rare: price has spent essentially the entire prior six hours pinned near the bottom of its range. The buy condition (WPR < -99.9) only fires when the market is in a deeply capitulated state on a slow lookback, not on a brief intrabar dip. The mirror condition for sells (WPR > -0.1) is the same idea on the overbought side.

When the long condition fires, the entry is executed through OpenBuy() at the current ask with InpStopLoss=50 pips below and InpTakeProfit=150 pips above — a fixed 1:3 risk-reward. The code computes sl = Ask - ExtStopLoss where ExtStopLoss = InpStopLoss * m_adjusted_point (the adjusted point doubles on 3/5-digit brokers, so 50 pips stays 50 pips regardless of quote precision). The same pattern runs in mirror for sells: bid minus 50 pips for SL, bid minus 150 pips for TP. If InpCloseOpposite is true (the default), opening a buy immediately closes any open sell on the same magic and vice versa, so the EA never holds opposing positions simultaneously.

The trailing system is unusually tight for a system that brackets 200 pips of total range. InpTrailingStop=1 pip with InpTrailingStep=1 pip means the stop ratchets one pip at a time, but only after the trade has moved at least ExtTrailingStop + ExtTrailingStep (two pips) in profit. The Trailing() function runs every tick, not just on new bars, so the stop is re-evaluated on each price change. The combination of a 150-pip TP and a 1-pip trailing ratchet means the EA tends to capture most of a fast M1 spike: the trade can run to TP untouched, or the trailing stop can lock in profit as price reverses. There is no partial-close, no breakeven step, no second-stage trail — the trailing is a single, atomic, never-loosens ratchet.

Position management is split between two execution paths. The entry path runs on new bar only — OnTick guards on time_0 == PrevBars and bails out if the bar hasn't changed since the last evaluation, which means at most one signal per minute per direction. The trailing path runs every tick. The retry helpers TryClose_EX14009, TryClosePartial_EX14009, and TryModify_EX14009 are defined but only TryClose_EX14009 (used in ClosePositions) and TryModify_EX14009 (used in Trailing) are actually wired into the live flow; TryClosePartial_EX14009 is dead code. Each retry helper makes three attempts and sleeps 100–200 ms on REQUOTE / TIMEOUT / PRICE_OFF / PRICE_CHANGED before giving up. Slippage tolerance is set via m_trade.SetDeviationInPoints(10).

The time gate is Timecontrol(), which uses InpStartHour=7 and InpEndHour=17 by default. The logic is unusual: it handles both overnight wraps (InpStartHour > InpEndHour, allowing the window to cross midnight) and same-day windows (InpStartHour < InpEndHour, allowing only hours within the range). The default 7-17 covers the London and New York overlap on most broker timezones, which is when XAUUSD (the suggested pair) sees the cleanest directional moves. The control returns true if InpTimecontrol is disabled, so flipping the boolean disables the gate entirely.

There is no global drawdown cap, no equity-curve protection, no daily loss limit, and no max-position guard beyond the close-opposite behavior. Lot sizing is fixed via InpLots=0.1; there is no risk-percentage calc, no balance scaling, no recovery multiplier. The OnInit() block adjusts for 3/5-digit quotes, validates InpLots against the broker's SYMBOL_VOLUME_MIN/MAX/STEP, sets the magic via m_trade.SetExpertMagicNumber(m_magic), picks a filling policy by symbol, and creates the single handle_iWPR indicator handle. OnDeinit() is empty — the handle is released automatically when the EA unloads.

The WPR period of 360 is the single most important parameter to understand. Drop it to 14 and you get the standard noisy WPR, which fires constantly on M1 and produces whipsaw losses against the trend. Raise it further (e.g. 720 for 12 hours) and the signals become so rare that the EA trades only once a day. The default 360 is calibrated for XAUUSD's typical M1 volatility profile: deep capitulation events on a six-hour window happen a few times per session, and the 1:3 RR with a 1-pip trailing stop is sized to capture the snap-back without getting stopped out by intrabar noise.

For live use, the practical constraints are broker-side, not strategy-side. A 50-pip SL on XAUUSD M1 is roughly $5 of risk at 0.1 lot on most brokers, and a 150-pip TP is roughly $15. The EA needs an ECN or RAW-spread account so the WPR extreme reading isn't masked by a wide spread. There is no recovery multiplier, no martingale, no grid — every trade is standalone with a fixed 1:3 bracket. Backtests on XAUUSD M1 with default parameters are most informative across a 6-month window that includes both a trending and a ranging regime, since the WPR-at-extremes approach performs very differently in each.
