CM_Donchian Channels V3 revised by JustUncleL

This is a revised version of Chris Moody's "CM_Donchian Channel Modified_V2" script.

ChrisMoody:
"Modified Donchian Channel with separate adjustments for upper and lower levels. Purpose is if you expect big move up, use lower input for example 3 or 4, and longer upper input, eg. 40 - 100 and use lower input line as a stop out. Opposite if you expect big move down. Mid Line Rule in Long Example: If lower line is below entry take partial profits at Mid Line and move stop to Break even. If Lower line moves above entry price before price retraces to midline use Lower line as Stop...Opposite if Shorting."

...Small work around
