AFL Explanation

Here is the explanation of each line of code:

// Define Inputs
WeeksBack = Param("Weeks Back", 20, 1, 100, 1);
Threshold = Param("Threshold", 1, 0.1, 10, 0.1);

Param function defines the inputs for the trading strategy. In this case, we have two inputs: WeeksBack which is the number of weeks to look back for the previous high and low, and Threshold which is the percentage distance from the previous high/low to define the breakout level.

// Define Variables
PrevHigh = Ref(HHV(H, WeeksBack), -1);
PrevLow = Ref(LLV(L, WeeksBack), -1);

Ref function is used to reference a previous bar’s value. HHV and LLV functions are used to calculate the highest and lowest values over a specified period. In this case, we’re using Ref to get the previous high and low values, respectively.

// Calculate Breakout Levels
BreakoutLong = PrevHigh + Threshold * (PrevHigh - PrevLow);
BreakoutShort = PrevLow - Threshold * (PrevHigh - PrevLow);

The BreakoutLong and BreakoutShort variables are calculated using the PrevHigh and PrevLow values, and the Threshold input. BreakoutLong is the previous high plus Threshold times the difference between the previous high and low, while BreakoutShort is the previous low minus Threshold times the difference between the previous high and low.

// Define Trading Signals
BuySignal = C > BreakoutLong;
SellSignal = C < BreakoutShort;

BuySignal is true when the closing price is above the BreakoutLong level, while SellSignal is true when the closing price is below the BreakoutShort level

// Plot Breakout Levels
Plot(PrevHigh, "Previous High", colorGreen, styleLine);
Plot(PrevLow, "Previous Low", colorRed, styleLine);
Plot(BreakoutLong, "Long Breakout", colorBlue, styleLine);
Plot(BreakoutShort, "Short Breakout", colorBlue, styleLine);

// Plot Buy/Sell Signals
PlotShapes(IIf(BuySignal, shapeUpArrow, shapeNone), colorGreen, 0, Low);
PlotShapes(IIf(SellSignal, shapeDownArrow, shapeNone), colorRed, 0, High);

// Apply Trading Signals
Buy = BuySignal;
Sell = SellSignal;

• The first 4 lines use the Plot function to plot the previous high and low levels, as well as the BreakoutLong and BreakoutShort levels on the chart. Plot function takes 4 arguments: the value to be plotted, the name of the plot, the color of the plot, and the style of the plot.
• The next 2 lines use the PlotShapes function to plot arrows on the chart when a buy or sell signal is generated. PlotShapes takes 4 arguments: the shape to be plotted (in this case, an up arrow for a buy signal or a down arrow for a sell signal), the color of the shape, the layer (0 means the default layer), and the price level at which the shape should be plotted (in this case, the low for a buy signal or the high for a sell signal).
• The last 2 lines use the BuySignal and SellSignal variables to generate trading signals. When BuySignal is true, the Buy variable is set to true, indicating a long position should be taken. Similarly, when SellSignal is true, the Sell variable is set to true, indicating a short position should be taken. These variables can be used later in the code to generate trades using the Buy and Sell functions.
