Quote from Ghost of Cutten:
They don't separate it.
IMO this is not too bad a decision - anyone buying 60% away from the recent print knows it's a good chance of being a trade error. At least they didn't fuck people by cancelling things 10-20% away.
A superior option would be to remove trade busts altogether, and replace them with trade adjustments to the high or low of the day. I.e. if you bought at 70% down, and they "bust" 60% down or lower, then your trade gets reset to 60% down. Otherwise it's unfair as i) it creates catastrophic short exposure to anyone who bought at 61% down and sold at 50% down; and totally fucks shorts who covered at 61% down ii) it penalizes people who took risk during a crash by submitting low bids when it could have been a terrorist attack, accounting fraud, or other legitimate reason for a huge crash iii) it arbitrarily rewards people who bought just above the bust limit instead of just below it.
Trade busting is a stupid policy overall.
I think you're on to something here. The possibility of waking up one morning to an open leveraged position I closed out the day before gives me the fucking shivers.
I think the right policy moves money to square it up, but leaves the net positions where they were at the end of the day.
