Pipsgrowth EX10002 Momentum-Scalper

EX10002 Momentum-Scalper reads gold momentum through a pair of Relative Strength Index lines stacked on top of a slow 200-EMA regime filter, and enters only when both sides of the indicator agree. On every closed bar the EA pulls two RSI buffers from the same close price stream — a fast 9-period RSI and a slow 21-period RSI — and watches the spread between them. The fast line is the timing wheel: it has to clear the slow 50-line (long) or fall under it (short) at the same time it crosses the slow RSI. The slow line is the conviction filter: the 21-period RSI has to read above 50 for buys and below 50 for sells, so the EA never fades a regime in motion. The 200-EMA on the same chart is the final gate — the bar-1 close has to be above it for buys and below it for sells. No single one of these three legs is enough on its own; all three have to align on the same bar, which is why the signal fires relatively rarely even on a busy pair like XAUUSD.

When a true crossover is not available, EX10002 falls back to a continuation branch. If the previous bar closed above the 200-EMA with a body covering more than 50% of its range, the fast RSI already above the slow RSI, and the fast RSI above the buy level (55 by default), the EA will treat that as a strong-trend bar and take the long. The mirror branch fires shorts under the EMA with the same body-quality and threshold conditions. Continuation entries are flagged with a 60/100 confidence score; crossover entries score the magnitude of the RSI separation, capped at 100.

Before any order goes out, the trade has to clear three independent confirmation gates. The first is regime: ADX(14) has to read at least 15 to certify that the market is trending, the current ATR has to sit between the 15th and 95th percentile of its last-50 reading (a cheap proxy that filters both dead-vol and spike candles), and the Bollinger Band width at 20 periods and 2.0 deviations has to be wider than the 10th percentile of its recent history so the EA refuses to trade in a tight squeeze. The second gate is higher-timeframe alignment: the EA copies an H1 50-EMA and requires the H1 close to be on the same side of that EMA as the trade direction. The third gate is participation: the current bar's tick volume has to be at least 80% of the rolling 20-bar average, otherwise the move is treated as unrepresentative and the trade is skipped.

Sizing follows the same conservative logic. The stop distance is two ATRs (InpATRMultiplier=2.0 by default), but never narrower than the broker's published stops-level floor. The take-profit sits at the same ATR distance scaled by the reward-to-risk multiple (InpMinRR=1.0 by default, so 1:1). Lot size is computed from the risk percent (3% of effective capital) divided by the loss-per-lot at that stop distance. The fixed-lot input (0.01) acts as a fallback when risk percent is set to zero. The capital cap is opt-in via InpCapitalCapAmount — if set, effective capital becomes the lesser of that number and account equity plus today's realized PnL, and entries are blocked below a $50 floor.

Once a position is live, EX10002 runs four management threads in series. The first watches the fast RSI for momentum decay — if the position is long and the fast RSI has dropped back under 50 while price is still above the entry, the EA closes the trade on the assumption that the impulse is gone. The second watches the signal evaluator for a counter-direction signal and exits on the first bar that flips. The third checks whether ADX has fallen out of the regime window and closes if the trend has died. The fourth is a hard time stop at 240 bars in trade, which forces a settlement even on quiet ranges. On top of those soft exits, the EA installs a one-shot break-even stop at the InpBETriggerR multiple (1R by default), shifted five points past entry to cover spread and commission. If InpUsePartialTP is on, the EA also closes half the position at the same 1R level when the volume is large enough to be split above the broker's minimum lot. After 1R is locked, an ATR trailing stop takes over at 2.5× the current ATR, ratcheting tighter on every bar that prints a new favorable price.

Risk is capped on three time horizons. Each trade risks 3% of effective capital. The day caps at 15% of effective capital in realized PnL, and the week at 25%. Cooldown fires after three consecutive losses — the EA blocks new entries for twelve bars on the working timeframe. The signal evaluator only runs on closed bars (g_lastEntryBar guard), so a single fast-market cascade cannot open a cluster of entries. Sending retries are double-layered: TryEntry catches transient REQUOTE/PRICE_OFF/TIMEOUT codes and resends once with refreshed prices, while the close and modify helpers loop up to three times at 200ms backoff before declaring failure. Filling mode is auto-selected from the broker's published mask, preferring FOK and falling back to IOC, then RETURN. The OnTester formula scores optimization runs as net profit times profit factor divided by one plus the relative balance drawdown, with a 30-trade minimum so a single lucky streak cannot game the criterion.

The 12-layer header in the source is not aspirational here — every layer has matching code. REGIME is the three-axis ADX/ATR-percentile/BB-width check. SIGNAL is the dual-RSI crossover with body-quality continuation fallback. ENTRY is the TryEntry path. CONFIRM is the H1-EMA plus tick-volume check. NO-TRADE is the capital floor, daily/weekly loss caps, cooldown, spread filter, session window, and one-bar-per-bar guard in OnTick. CAPITAL CAP is the opt-in effective-capital computation. RISK and SIZING are the per-trade percent and ATR distance calculation. MANAGE is the break-even, optional partial TP, and ATR trailing. EXIT is the four-thread soft-exit stack. SCALING is the lot rounding and broker-step clamp. OnTester is the custom criterion. The 200-EMA is the spine that ties the whole structure together — every entry and every exit references price relative to it.
