Here is a 4Hr EURUSD strategy where I decided to combine 4 different supertrend indicators to filter out weaker trends.

The parameters are mostly standard (as originally found) with the exception of a variable named ‘margin’ that defines the minimum distance between two of the specific trend lines.

Defparam cumulateorders = false

possize = 1
