Price minus EMA

[T2020]

Hi ,
It was fairly easy to create a EMA plus 20 cents , so now I'm wondering if creating "price minus a EMA" would be basically the same thing . : Could I just Edit the EMA again and put (your word for the close of Price ) in front of the
{
Value.Set(CurrentBar == 0 ? Input[0] : Input[0] * (2.0 / (1 + Period)) + (1 - (2.0 / (1 + Period))) * Value[1]);
}

Formula ... ???

I did not look at the code but if you were able to do the plus 20 cents, just create another indicator and minus the 20 cents.

OK , you didn't understand the question . I wasn't looking for the opposite of
what I did before . I want the Last closing price - a exponential moving average . Kind of the same thing as the Dinapoli Detrend only using and EMA
instead of a SMA and being able to use a moving average of the high or Low if
I want .
