I use bookmap for data/decisions (DX Feed for stocks), TWS is only for executing.

One of the common complaints about TWS is the charting but I don't use any indicators that aren't in bookmap (which is very few) so you need to decide for yourself how you deal with that. TWS hotkeys are also horrendous so I try avoid using them which is why I say not suitable for scalping (or basically if you don't have time to fill out orders manually, after they're filled out you can drag to adjust), I've had to adjust the way I trade to cater for this (basically prepare in advance). I am going to look into a better way to execute at some point but imo $165 is excessive, essentially it's because you have to pay data again when I don't even use it and DAS also gave me execution problems anyway (I'm currently in Australia so the delay is not great on DAS here).

Hi Martin. Thanks for the feedback. I am getting more and more comfortable with TWS. Its actually pretty good. The recent enhanced charts are nicer but a bit glitchy. I have the DXFeed with Bookmap and am going to let DAS expire this month. Wihtout DAS, does your TWS pick up data from bookmap or do you have data for both TWS and Bookmap?

No TWS doesn't pick up data from bookmap. I don't use data for TWS, I have very limited data there free (not sure exactly what it is) but it is very limited in terms of volume etc if you don't have data it also has some impact on certain features you can use like certain hotkeys. I don't think it's really expensive if you did want it but I just don't really care because I don't use any features on it.
