Amibroker Afl Code Access

Data series like Close , Open , High , Low , and Volume . Operators: Mathematical ( −negative ) and logical ( >is greater than AND , OR ) operators.

// Define user-adjustable parameters FastPeriod = Param("Fast MA Period", 12, 2, 50, 1); SlowPeriod = Param("Slow MA Period", 26, 2, 200, 1); // Calculate the indicator arrays FastMA = MA( Close, FastPeriod ); SlowMA = EMA( Close, SlowPeriod ); // Define dynamic visual properties LineColor = IIf( FastMA > SlowMA, colorGreen, colorRed ); // Plot the price data and indicators Plot( Close, "Price Chart", colorDefault, styleCandle ); Plot( FastMA, "Fast Moving Average", LineColor, styleLine | styleThick ); Plot( SlowMA, "Slow Moving Average", colorBlue, styleDashed ); Use code with caution. Explaining the Functions:

Since you requested a "paper" on , I have structured this response as a comprehensive technical guide or white paper. It covers the architecture, syntax, and practical application of the Amibroker Formula Language (AFL).

StaticVarSet("DebugCounter", 0);

The feature in AmiBroker allows you to scan thousands of stocks simultaneously to find assets meeting your setup criteria. To convert AFL code into a scanner, utilize the Filter variable and the AddColumn() function. Here is an AFL script to scan for Volume Breakouts :

When backtesting, verify you aren't referencing future bars. For example, writing Close[i+1] introduces a look-ahead bias that invalidates performance testing.

All sample code in this guide is based on documentation for AmiBroker 6.90 and earlier; please refer to the official AmiBroker website and the most up-to-date user guide for the latest features and syntax. amibroker afl code

Let’s assemble a complete, tradeable strategy. This is a .

// Visualizing Signals PlotShapes(IIf(Buy, shapeUpArrow, shapeNone), colorGreen, 0, Low, -15); PlotShapes(IIf(Sell, shapeDownArrow, shapeNone), colorRed, 0, High, -15); Data series like Close , Open , High , Low , and Volume

: For truly "deep" features (neural networks), users often export AFL data to Python or R using Amibroker ADK AFL to Python COM links to monitor the values of your features in the Log window or AddColumn() Exploration to see raw numerical outputs for each bar. Performance : AFL is designed for fast array and matrix processing , so avoid

: Built-in cash management engine. It handles stop losses, trailing stops, and profit targets with execution priorities natively managed by AmiBroker's C++ core. 5. Advanced Optimization and Scans
