Personally, I used to set a percent of account balance in default trade settings which is based on my risk tolerance. I have stepped away from this approach and use a strategic SL at the level on weekly timeframe for Daily/H4 entries (and Daily TF for H1 or lower TF entries).
If direction and scale of profit taking comes from higher timeframe based on your hindsight and anticipation, I feel even SL should be driven by a similar guidance.
Perhaps, Geoffrod, Cameron and other successful traders mentioned by Graeme in his recent posts could continue to share their experience for the benefit of new comers who are interested in Graeme's approach and to keep this thread alive.
Have a great weekend.
Staying in my lane...
