Take MACD for example: It is made up of macd, avg and diff
Perhaps one would want to long permission if macd were above 0 and short permission if macd were below 0
In addition, if macd were above its avg, then the long setup would be different than if macd were below its avg ... with the inverse true for shorts.
For example, if macd were above its avg, the trigger might be expected as a reverse off the middle of a donchian channel, or the bottom channel if it had crossed the avg ... similarly the revers for a short ... using middle and top of donchian channel
How would one accomplish this?
