It is never as bad as it looks.
My main issue issue would be if my new chosen platform didn't support the same order types i am used to using on IB.
The API calling bits of my ATS can always be re written.
I could even keep my IB data feed bits, and still get my data from IB, initially anyway.
I would first re-route my order placing logic, so it doesn't go to IB but the new platform. Then i would move over the execution reporting calls, so i get back fill reports.
I think the main bit of work would be any new logic needed to compensate for missing order types.
There are startups like Alpaca, but may be going about this a wrong way, focusing on free/zero commissions and selling the order flow, instead of focusing on smart routing, advanced order types, margin, etc.
But it may be worth watching or even trying for some strategies.
. Do you think they forgot the Swiss Franc debacle? https://www.google.com/amp/s/fortune.com/2015/01/16/swiss-franc-400-million-losses/amp/VIX peaked three weeks ago at ~85 and has since dropped by 50%.
Yet IB is continuously increasing their margin requirements as VIX is dropping. Every day is higher than the last. As I check it this morning, Portfolio Margin is barely better than reg T. I'm scared that it can just keep going higher and higher, because why not? Their system appears to have no sense to it. I might actually end up downgrading to a reg T account at some point if that gives more margin
I always believed IB's risk aversion was a good thing that protected customers like me, and people who complained about margin were just whiners who were taking too much risk anyways (naked option selling, etc). Seeing how their system behaves now, I no longer believe this.
This is, by far, the most profitable trading environment I've ever seen in my career. It might be once in a lifetime. And IB is hamstringing us with this goofy margin system. I am making a week worth of profits every day, but I could be making more than 2x that with a proper 15% PM account. (This is straight up equity trading by the way, cash neutral portfolios, no options.)
I hope IB gets their act together, but I am actively looking into switching brokers at this point.
We had gold trades today. I could not believe my eyes, Initial margin on 1 gold futures contract was almost $24,000. We were testing higher margin level of our account size during night and early morning. We wired more money today, just in case for next week.
I am like 24K - WTF.
Risk-free zero $$$ for Petterfy.
What kind of return is he getting on that on our excess margin?
His return is closing your GC position when it did not have to be closed, and him sucking the cash out of your trading account. Risk free $ zero.

Yup. But is correlation risk for IB. They have 100mm in equity and 5bn in customer deposits (for example). If everyone borrows the max under regt then IB has to borrow 5bn from some counterparty. If 2percent of the customers blow up, then IB is finished.
Further, If the repo lines/LOC get pulled then IB may not be able to fund all the customers who want margin. So they should make it more painful to borrow funds.
This is the systemic risk in the system right now.
As long as they have proper margin call & auto liquidation in place, they shouldn't face such a situation. Yes, gaps are more prone & frequent these days and they have to protect themselves and their customers. But we also have to remember that there are circuit breakers, which means that even at times of panic, there will be pauses and windows open for auto-liquidation of positions.
In these times, I agree with you, it's better to have higher margins (Reasonable) than to blow up.
