I had thought of it that way as well. It actually makes more sense to reduce your risk for greatest
SL 
. The reason I am trying this way is in case my first 2 or 3 trades stop out, then I can more quickly make back my losses with the 1 or 2 trades left in case it was just a false reversal. However, if there is a
trend 
reversal, then it will just compound my losses even more. Hopefully that doesn't happen too often though. At this
point 
I'm just playing around with that strategy, but I believe I will try yours as well. I am certainly open to correction on my strategy if my thinking isn't quite on track.
