Ähemm, with this so easy you will get probably endless much Buy`s

You have to add some other rules. like once a day, or you count your open Positions

example: add 1 Buy if price is 10 pips unter open and not more than 1 Trade open (< 2)

That`s pretty simple...

if you add positive Value you add to running Position
if negative Value (unter the open price) you add (average down) to a losing one
