Where does the money go when I click SELL but I didn't BUY?
Rocket Chimp
Nothing leaves your account the moment you press SELL — you're opening a short position. Your broker sells the borrowed asset now, and your margin is held as collateral. When you close, the position is bought back: if the price fell, the difference lands in your balance as profit; if it rose, it's deducted. The money never "goes" anywhere — it settles against your margin at close.

Create a Statistical Arbitrage MT5 algorithm that automatically derives Notional Value and Z-Score
Rocket Chimp
Here's a compact pair-trading EA — notional derived from contract size × price, signals on a rolling z-score:
// Statistical Arbitrage — pair: EURUSD / GBPUSD
double NotionalValue(string sym, double lots) {
double contract = SymbolInfoDouble(sym, SYMBOL_TRADE_CONTRACT_SIZE);
double price = SymbolInfoDouble(sym, SYMBOL_BID);
return lots * contract * price; // notional, quote ccy
}
double ZScore(double &spread[], int period) {
double mean = 0, sd = 0;
for (int i = 0; i < period; i++) mean += spread[i];
mean /= period;
for (int i = 0; i < period; i++) sd += MathPow(spread[i] - mean, 2);
sd = MathSqrt(sd / period);
return sd == 0 ? 0 : (spread[0] - mean) / sd;
}
void OnTick() {
double beta = HedgeRatio("EURUSD", "GBPUSD", 200); // rolling OLS
double z = ZScore(spreadSeries, 100);
if (z > 2.0) OpenPair(SELL_A_BUY_B, beta); // spread rich
if (z < -2.0) OpenPair(BUY_A_SELL_B, beta); // spread cheap
