Auto MTF Standard Deviation Channel

The task is quite simple. It consists in creating a standard deviation channel which automatically adjusts to a determined period (the calculations are made on the last closed candle and not on the active candle).

The indicator must be multi-timeframe, which means I can put a channel calculated on the H1 on M15.

Also, I want to be able to have more than one channel on the same chart without bugging and to be able to choose the two deviations that will make up the channel.

Fill the area between Dev1 & Dev2 with color and extend right.

Inputs:

input ENUM_TIMEFRAMES timeframe= PERIOD_CURRENT;

input int Period=96;

input double Dev1= 1.00;

input double Dev2= 2.00;

input bool Alerts=true;

input bool ExtendRight= true;

input bool ColorFill=true; // Set the color fill transparent to 90

input bool ShowLines= true; // if false ---­> Always show mid line

input color UpperChannel=clrRed; //Same color for the upper lines

input color LowerChannel=clrGreen; //Same color for the lower lines

input color MidLine= clrBlack; // Always show mid line
