place stop loss at % drawdown

[PipTheRipper]

Hi, I am wondering, is there a way to use a fixed lotsize and place the stop loss based on how much i want to risk per trade?

Kinda the opposite to the typical way where we tell the ea where to place the stop loss, and have the ea calculate the lotsize based on the distance to sl level.. Hope my questions is clear.

Get the pips value of the pair then calculate the no of pips for SL based on amount to risk.
