There are two parts of the merger. customizing ToS to work with Schwab customers merging TDAmeritrade customers with Schwab's customers. (much bigger work) I've talked to them(Schwab) and they said ToS will be available to Schwab customers like me sometime in 2021. True, not all the merger will be complete in 2021, but that part I do not care about...I left TDAmeritrade already.
I was trading futures at TD Bank, but Schwab's commissions were lower and they would not match despite me generating a $4500 commission in six months. Also, why stay on a sinking ship? My personal broker left/or was let go, I could never talk to anyone, at Schwab 7/24 under a minute I talk to someone in the US. My investments are at Schwab and my trading is at IB.
