Streak algo trading with CNC

I have been exploring algo trading with streak recently.
I see support for CNC delivery based algos.

With my knowledge with CNC you can only sell stocks after T+2 days. Is it implicitly supported in streak CNC signals.

if not, any other strategy to use streak for trading in 1-2 weeks duration.

No such rule, unless it’s a Trade to trade stock. You can buy shares and even sell it on the same day using CNC.
