// Example: Calculating a custom stop-loss using a loop stop_level = Null; in_trade = False; for( i = 0; i < BarCount; i++ ) if( Buy[i] ) in_trade = True; stop_level[i] = Close[i] * 0.95; // 5% stop loss else if( Sell[i] ) in_trade = False; stop_level[i] = Null; else if( in_trade ) // Maintain the stop level from the previous bar stop_level[i] = stop_level[i-1]; Plot(stop_level, "Stop Loss", colorOrange, styleDots); Use code with caution. 6. Best Practices for Writing AFL Code
// Calculate Moving Averages ShortMA = MA(Close, ShortPeriod); LongMA = MA(Close, LongPeriod); amibroker afl code
Buy = Close > MA( Close, 10 ) OR Close == 1.1 * Ref( Close, -1 ) AND Volume > MA( Volume, 10 );
