@Jahruhay Yes the formula is the same, only difference is that I prefer a 20 SMA (120 SMA on 4H) on a daily chart, where dennis is using a 34 SMA (200 SMA on 4H), but there is no any significant different.
It means if you traded using a 200 Pip stop loss for the past five years, your average R:R would have been 3.08 R.
It is a free indicator you can find it online, I found it from Forex Factory Forum.
I am using a 3 ATR stop all the major pairs, except for USDCHF where I use a 4 ATR stop, and as the market goes in my favor I scale out while trailing my stop. Same applies if the market goes against me, I scale out make the risk to a minimum level.
Hope this helps
