The BigBarSound indicator plays sound alerts when candlestick body size exceeds a certain value.

The size can be considered as Close-Open (current price - candlestick open price) or as High - Low, the calculation mode is selected in the settings. It works on any timeframe and symbol.

Indicator input parameters:

input uint            BarPoint    = 200;            // Minimum candle step size for the signal

input string          WavFile     = "alert.wav";    // The name of a sound file
