What roadblocks? TOS is also TDA - different interface same broker (schwab eventually once the merger completes) I execute both of these orders types on tos/tda and ib daily.

Nope - every option leg is ~ 65 cents/contract

Python for all the Execution/API - some of my backend is still in java. Anyway the TDA API docs have good curl examples which easily translate into python.

Easy to use - all rest based - the initial authentication is somewhat weird but once you’re over that you get a token that’s valid for 90 days. It’s fast enough for what I do - they don’t document their limits too well (or I haven’t found that info) and sometimes I send too many requests and...

Tdameritrade - they have significantly less shortable stock compared to ib though

Im sure that’s what he ll say ;) Account blown out - check

It's a completely different approach to my own trading (he trades unhedged and directional) -> uncorrelated.

That actually depends how you trade. I mostly pair trade automated and for that I have better lock with mean reversion if stocks don't get spooked by a silly tweet. I can see how shorter term traders will like this environment though.

I'd take huge comfort knowing that my money is locked up in some foreign exchange after they got compromised by a hacker. I wouldn't worry about their capitalization to cover a 50 million loss at all, I'd fully understand that I couldn't withdraw my money under these circumstances.

I think you can even simplify that. How about a UI that's a single text field how much money you want to make today. You put it into the text field and the system auto-generates the profit for you. The learning curve of putting the amount into the text field is pretty simple and the user...

Are you sure? You're definitely right for IB but I'm also on 0 commission on TD Ameritrade and my option trades have moved to the new commission schedule (0.65/leg). I haven't done any stock trades since the change, all of them were manual but I didn't think they'd still charge my old...

Ask yourself: Is there more signal or more noise in the market? I think 0 commissions were a game changer.

I disagree. In the 0 commission environment where you just pay regulatory fees you can easily martingale and make an easy buck - imo. I haven't daytraded in the 90s but with the whole 0 commission I'd say it's easier than ever (with good capital). It's not likely that you pick the wrong...

You state your personal opinion like it's a fact - I've a big ego too but I wouldn't venture to make such broad statements. As a former system developer on C2 (when profit sharing/% split was more lucrative) I don't think the next 2 statements are true at all. Yes you can game C2 by selling a...

Vpsdime - good value for what you pay Been using them for over 3 years with 2 servers - no regrets

I don’t base my trades on tweets but if a tweet reverses overall market direction with a crazy sharp move my risk management still takes me out and I lose. I’m not sure who listens to CNBC or Bloomberg but they don’t move indexes that’s for sure. They would probably like to but they have no teeth.

Tariffs became weapons of financial destruction . A single tweet about the same thing (they want to come to the table - we're making good progress - they walked away and didn't comply with what we discussed - over and over...)literally moves markets more than non farm payrolls or the fed. I...

Great input tom, rather than answering just bashing it with full force - your tribe of "experts" will give you the head nod that only a small subset of you elite traders are deserving and the rest of us are just a bunch of idiots. I know you know this but there was nothing meaningful in your...

I need help !! I'm working on a system and attached are my trades (this is the output of one monte carlo run that's somewhere in the middle). Here's what I need help with: If I calculate the median of these trades I get ~ 118. If I look at the average of these trades I get only 22.8. This...
