EXAMPLE: say you have $5,000 in your account...daytrade margin of XYZ contract is $8,000....you put a buy market order in and it goes through and 1 minute later you sell for a $500.00 profit... what would happen? *nothing, just keep the profit? *trade gets busted at a later time? *you get a margin call later in day and need to bring account to $8,000? has anyone ever seen this happen?again, remember, the trade only lasted 1 minute... I know "most likely" the trade would have never gone through on a given platform but...just wondering as to if this has ever happened?
