Quote from DerekD:
Lock limit means you can't sell below the limit. And the first tier of lock limit only lasts for 10 mins. But markets don't gap to lock limit.
What's more, we're talking about intraday trading - not holding overnight were almost all lock limits have occured.
Lastly, OEC disallows reduced margins for accounts that drop below $2000 in equity. IB should adopt such a program. Perhaps with some sort of tiered individual account triggering algo given that they allow for the trading of an assortment of products.
Or, if an account's only trading permission is to trade futures, IB should exempt daytrade margin suspension rules since this sort of account would be eaiser to monitor with a simple algorithm. In fact, since IB is into the technology thing, if all positions are covered with a stop, IB should allow 25% of SPAN margins for a futures only account.
Just my opinion.
