Today was the 3rd day this month that I have missed trading due to unnecessary margin calls from my clearing house. My clearing house said I over spent my equity buying power by >$20,000. I do not max out my BP and am pretty sure my software would prevent me from doing so. I saw that the trade logs my broker uploaded to the clearing house are different from the trading activity I save from my platform logs. Most of my trades had been bunched together 3, 4, 5 at a time on each side and the commissions were grouped as well. This put the time stamps out of order and showed me having false positions of either 40,000 shares long or short. I pressed my broker to rectify it each time and they would pull a few trades out of my account to fix the situation but this is getting ridiculous. Is this fair game for my broker to be doing this? My last broker never did it and they were using the same CH. Thanks.
