Your account doesn't have to be inactive for 90 days. You can trade everyday. Here's how:
1. Request that your broker disables your margin and reverts your account to strictly "Cash". Not having access to Margin, you will be allowed to trade, because now it's only your money you're putting up to market risk.
2. Your trades will have a "settling" requirement imposed on them, i.e. every BUY in a round-trip trade will have to settle, which normally takes 3 business (trading) days. E.g. you BUY and SELL stock XYZ the same day, say - Monday, but you won't be able to use the proceeds from the SALE side to trade the same day, or Tuesday, because the purchase has to settle (almost like a written check that has to clear your bank). Usually, to continue this example, by Thursday morning your funds will became available again for trading.
3. Split your portfolio into three equal parts. E.g. if you have, say $21K in your account, designate $7K to your daily trade Buying Power. Use the first $7K to do a round-trip trade Monday, the second $7K to do the same on Tuesday, likewise the third $7K on Wedn. Thursaday morning your Monday trade will have settled, so you will have your first $7K available again for trading. On Friday the second $7K from your Tuesday trade will settle --- you get the idea...
To those who think trading with less than $25K is impossible/not feasible, I have only one thing to say: I manage to make betw. $250 - 300/day trading this way, which is a daily gain level where it's duplicating my daily wages from my regular job. I'm fairly confident that as long as you don't have to draw on your account for living expenses (as in: paying yourself a salary as a full-time daytrader), its compound growth should get you fairly quickly over the $25K line, at which point you will be able to use leverage (margin) again, with no restrictions on frequency of trading. Good Luck!!!
