Amibroker Afl Code Guide

for(i=0; i<BarCount; i++) myArray[i] = MA(C, 200)[i];

if (Sell AND currentPos == 1) { currentPos = 0; StaticVarSet("MyPosition", 0); } Using AmiBroker’s DDE or COM interface , you can bridge to Interactive Brokers, Tradier, or a custom API. amibroker afl code

// Add custom metrics stats = bo.GetPerformanceStats(0); // 0 = Long positions maxDD = stats.GetValue("Max system % drawdown"); for(i=0; i&lt;BarCount; i++) myArray[i] = MA(C, 200)[i]; if

// --- Exploration for Equity Curve Analysis --- SetBarsRequired(500, 0); Equity = Foreign("~~~EQUITY", "C"); // Internal equity array MonthlyReturn = (Equity - Ref(Equity, -20)) / Ref(Equity, -20) * 100; Filter = 1; AddColumn(MonthlyReturn, "20-Period Return %", 2.2); AddColumn(Stdev(MonthlyReturn, 20), "Volatility", 2.2); Backtesting is where AFL truly shines. The default settings are good, but professional optimization requires custom metrics. 4.1 Custom Backtest Interface (CBI) You can override AmiBroker’s core logic using SetCustomBacktestProc . posSize = 10000 / volatility

// Adjust position sizing based on volatility for (sig = bo.GetFirstSignal(); sig; sig = bo.GetNextSignal()) { if (sig.IsEntry() AND sig.Symbol == "SPY") { volatility = ATR(10) / C; posSize = 10000 / volatility; // Inverse volatility sizing sig.PosSize = posSize; } } } Avoid curve-fitting. This snippet sets up WFO parameters:

// --- Exit Conditions --- SellSignal = C > BBUpper OR C < (BuyPrice - (2 * ATR_Val)); Sell = ExRem(SellSignal, BuySignal);
