Every trader have there own risk taking capacity, so it does not work always using stop loss and target at 1:2 ratio.
I do not use stop loss at all.
I create lots with very small quantity as per my margin available, so that if necessary I do averaging or else I just close the position at market if I found market is going totally against my position and there is less opportunity of bounce back.
Because by using stop loss I have seen many times the executed price get back but I had closed my position.
