I'd add more leverage.
Tighten stops then move it +1 tick.
This is actually how I day trade.
Yep - larger size for smaller target (full control required), smaller size for larger target (full control not required).
In theory it all sounds fine, but if you want to try and take money off the algo guys, you need the best tools and the best setups - otherwise, you might as well be pissing against the wind!
