I do not know TOS much but for DAS you can check here if you see its features are useful for you https://traderpeter.substack.com/p/trading-platform-choice

Hey fellow BBTers! For background:  I'm back for a second time with BBT after a year off.  I'm recently a member of the 'restructure' club after my employer has gone through some downsizing activities.  I've been paper trading for 3 years with decent success and had been planning to 'retire' in July...so the downsizing doesn't hurt my feeling considering a decent severance was included.  I'm taking this opportunity to turn my retirement into career #2...day trader...so I will be going live in the next week or so. I've been paper trading in TOS through TD/Schwab for 3 years.  I've been considering making a switch to IBKR and using DAS.  I know this is a DAS/IBKR heavy community, so I wanted to get thoughts from folks who have used both TOS and DAS in the last couple of years.  I'll be trading primarily Stocks, ETFs and Futures (beginning to study Options soon also, but haven't paper traded yet).  Does making the switch make sense?  Or should I stick to what I'm familiar with.  Any watchouts with either choice?  Any other thoughts? Sincere Thanks to all!  I hope to get to know y'all very soon! TraderChris

you can use the new syntax for orders but specifically this line drawing has been fixed in 5.7.9.3 only

I use the "BBT 3 month SIM" subscribtion. I try some of the hotkeys on your blog and this is not working. I will have to stay with the old syntax.  

Ok! Thz @peterB  It help a lot. I did not find on the DAS website any documentation on the new syntax. Do you have anything? I will use your blog for reference for now.
