02 / SIGNAL GENERATION PIPELINE

📡

LAYER 1 — TREND

M15 FILTER

LWMA(20) slope on M15 confirms the macro direction. Counter-trend signals are blocked entirely before reaching Layer 2.

M5 Close > LWMA · M15 slope rising

⚡

LAYER 2 — TRIGGER

STOCHASTIC

%K crosses above %D from below 30 (buy) or crosses below %D from above 70 (sell). Mid-range crossovers are discarded.

Stoch(14,3,3) · Extreme zones only

🎯

LAYER 3 — CONFIRM ★

BB + RSI

Price at Bollinger Band edge AND RSI in extreme zone. When both fire, signal upgrades to HIGH CONFIDENCE with +25% lot.

BB(20,2) band touch · RSI < 35 or > 65

✅

EXECUTE

ORDER SENT

Margin verified. Spread checked (<35pts). Session confirmed (08–17 GMT). ATR-based SL/TP calculated. Position opened.

ATR SL=1.5× · TP=2.5× · Risk 0.75%

03 / UNDER THE HOOD

ScalpGold_EA.mq5 MQL5 · v5.0

Signal Layer 1

TREND GATE

LWMA(20) on M5 and M15. Both must agree with the intended trade direction before the signal pipeline continues.

if(close > iMA(_Symbol,PERIOD_M5,20,0,MODE_LWMA,PRICE_CLOSE,1)
&& m15slope() == TREND_UP) {

Signal Layer 2

STOCHASTIC TRIGGER

%K crosses above %D only from below 30. Mid-range crossovers are rejected entirely — this is the key insight from the academic literature.

bool crossUp = K_prev < D_prev
&& K_cur >= D_cur && K_cur < 30;

Signal Layer 3

BB + RSI UPGRADE

When price touches the lower Bollinger Band AND RSI is below 35, signal strength upgrades. Position size increases by 25%.

if(close <= bbLower * 1.002
&& iRSI(...) < 35) strength = 3;

Risk Engine

ATR-ADAPTIVE SIZING

Stop loss and take profit dynamically computed from ATR(14). No fixed pip distances — every trade adapts to gold's current volatility regime.

sl = atr * 1.5; tp = atr * 2.5;
lot = (equity * 0.0075) / (sl / tickSize * tickVal);

Protection

DAILY DD HALT

If daily drawdown breaches 3%, the EA stops opening new positions until the next trading session begins. Non-negotiable.

if((g_dayStartEq - AccountEquity()) / g_dayStartEq
> MaxDailyDD / 100.0) return;

04 / INDICATOR STACK

LWMA

Period 20 · M5 + M15

Linear-weighted MA. Heavier weight on recent price. Dual-TF trend confirmation. Core of the strategy.

STOCHASTIC

14 · 3 · 3 · STO_LOWHIGH

Primary entry trigger. Crossover from extreme zone only. Eliminates mid-range noise entirely.

BOLL. BANDS

Period 20 · Deviation 2.0

Volatility envelope. Edge touch = high-confidence entry. Midline = partial exit trigger.

RSI

Period 14 · Levels 35 / 65

Secondary confirmation paired with BB. Both extremes must fire to qualify strength-3 signal.

ATR

Period 14 · All exits

Volatility-adaptive exits. SL=1.5×ATR, TP=2.5×ATR. Trail at 1.0×ATR. No fixed pip values.

SPREAD GATE

Max 35 points · Hard gate

Blocks trading during news spikes, liquidity gaps. ECN/STP accounts recommended.
