Do you know of there is a TT / IB connector?for IB's combo trader, you can 100 percent do outright vs outright bc i have used it before. if you are sensitive on slippage and you are doing large size, then maybe not the best choice bc once it shoots out the order, you are stuck amending them indiviuallly...
if you choose market order type on both, it can get messy for large orders, then you need TT.
