Will the brokerage firm entertain this? Because i asked their support team on the why was so much margins used even though the trades are not ITM. They only gave a vague answer. Im afraid hiring lawyers and experts tonhelp me on my case may cause higher expense than my loss....
From my personal experience with margin accounts.
The leverage% is a variable set by the trader, not a fixed percentage by the brokerage firm.
The range can be 2x to 10x or even more depending on your own risk appetite.
I can only deduce that your trader friend over-leveraged in this case with no stop losses in place.
It's not even a case of gap down, but just reckless trades without stop losses.......
When prices fell below your capital, a margin call was triggered, meaning you would have to top up cash to maintain your position.
If you did not top up your account within a stipulated period, your positions will all be forced close.
