// Simple Moving Average Crossover System in AFL
// This is a basic trading system that buys when a fast MA crosses above a slow MA

// Define the moving average periods
FastMA = 10;
SlowMA = 30;

// Calculate the moving averages
FastMALine = MA( Close, FastMA );
SlowMALine = MA( Close, SlowMA );

// Generate buy and sell signals
Buy = Cross( FastMALine, SlowMALine );
Sell = Cross( SlowMALine, FastMALine );

// Plot the price and moving averages
Plot( Close, "Price", colorBlack, styleCandle );
Plot( FastMALine, "Fast MA(" + FastMA + ")", colorRed, styleLine );
Plot( SlowMALine, "Slow MA(" + SlowMA + ")", colorBlue, styleLine );

// Plot buy/sell shapes
PlotShapes( IIf( Buy, shapeUpArrow, shapeNone ), colorGreen );
PlotShapes( IIf( Sell, shapeDownArrow, shapeNone ), colorRed );
