i understood the limit is 100 symbols. unknowing to me, it was trying to load all my watchlist, which is more than 100 symbols for sure, couldn't load a single chart. i shut it.
Better don't use it. I will stick to the old IB platform. IB uses complex English. Platform usually not user-friendly. That's why you need to do a demo on their platform.
If this new platform is designed by IB itself, I will not use it. Their TWS gave me nightmares. It's a very trashy platform. I would not expect the new one to be much better.
I just tried it, I like it, it feels smooth. Not as nice as TOS but it feels less intricate than TWS. I just converted a long iron condor into a put butterfly and it immediately worked it out and showed it as a whole strategy. TWS did not do that, or at least, I couldn't do it... and I had to monitor the single legs or group them into a dedicated tab. It looks compact, everything in one window and one just clicks around tabs. I can't find a "detach chart" options, and I like that, might suggest it. Charts are tradingview. Option chains look like the android app, plus this "Lattice" new version which is like a calendar with a visual of what I think might be IV... need to explore this new feature more. Payoff modelling chart is basic like on the App, slightly better than TWS but not like TOS. I think it's missing all the separate detachable tabs that one might find useful to run on multi display setup. But somewhere I read that they might introduce mosaic style tabs. Definitely better than their browser client portal trader for quick access and trade management.
Looks like very simplified version of TWS. I don't think it supports the API either since there is no config for it.
