the $25k threshold is a requirement for your account balance, not just your cash account and I imagine you must have more than that, considering your investment vehicle.haha. I have no cash everything that I make gets reinvested in shares. I trade through 4 IRA's and my after tax. I guess I will have to build some cash reserves because I see some opportunity on day trading options.
In an IRA, you have a different rule which is Free Riding. This applies to unsettled cash. Basically you can't use unsettled cash (in case of rapid buying and selling) to buy a security and sell it immediately after more than 4 times in a rolling 5 day period.
