i am a scalper (target+1,+2+3) and i am reading the jigsaw dom(because has bid$ask market orders &cum delta & reconT&S ,and executing trough jigsaw (i has the limitation of no bracket orders) or with a dom side by side (limitation to watch 2 things)
I need to find a solution/execution platform to help me to execute quick and reliable

Jigsaw+NT/AMP
Infinity DOM+Transact (now i have this)
