// Multiple Smoothing MAvg.custom
//----------------------------------------------------------------------------------------------------
// Differently from PRT's code, you don't have to select double or triple smoothing. You can actually
// use it as a common Moving Average with no smoothing since you are not forced to enter the second and
// third Period numbers. Only the first one has to be greater than 0.
// The second and third one, each one of them, can be 0, so that youy can have:
// - NO smoothing (second and third Period numbers set both to 0), so that it's like any common MA
// - single smoothing (PRT calls it double smoothing because it involves two MA's) when the first
// MA is smoothed by any one, and only one, of the other two MA's
// - double smoothing (PRT calls it triple smoothing because it involves three MA's) when the first
// MA is smoothed by the both the other two MA's
//
// Periods do not need to be ascending, nor descending; all of them are independent from the other two.
//----------------------------------------------------------------------------------------------------
// M1, M2 and M3 are the periods for the three MA's (0=do not use that average,
// for the first MA 1 is the minimum allowed)
// T1, T2 and T3 are the type of MA's

//ONCE M1 = 14
//ONCE T1 = 0 //0=sma, 1=ema, 2 =wma,...
