Man i feel you pain. I had a horrible experience with Interactive Brokers. I was trading an option strategy called a credit spread. If your familiar with these you know your maximum loss is limited to the distance between your strike prices and thats what you put down into margin. The margin stays fixed it doesnt fluctuate. So i had excess liquidity and a fixed margin and these idiots force liquidated a portion of my spreads costing me over $100k in losses via their auto liquidate algo. I didnt know what the hell was going on at the time i was being force liquidated and couldnt get a straight answer from them. They wouldnt turn off the algo and i was liquidated three days in a row. I opened an account with thinkorswim and transfered all my positions and cash over there as fast as i could before i was completely cleaned out.
Later i found my gross position value to excess liquidity exceeded their 50:1 threshold. How is that even relevant to a fixed loss trade? Where is this disclosed in my their margin agreement i signed? It's no where. I'm currently going through FINRA arbitration to try and recover my money. They hired a crafty lawyer who's arguing that IB can change their margin policy at any time to screw me over and that Finra reccomends brokers adopt stricter margin policies than the industry standard, so they use it as a way to rip off people under the guise they are protecting the firm from reckles traders. No ones capital was at risk but my own and i had the amount to cover the worst case scenario sitting in margin. I've never had such a problem like this in all my years of trading credit speads.
A buddy of mine who was going to open a hedge fund with IB to trade credit spreads the same way and would have gotten wiped too if i didnt warn him as they don't disclose this. When he brought up what happened to me they said they would review the accounts they are planning to force liquidate more carefully in the future and would not apply the algo to credit spreads. I saved the email this was in, it was from the same guy who was my representative at IB, John Seeberg.
If you have any advice for me in fighting these crooks please let me know, my hearing is in December.
