Pattern Day Trading

You avoid pattern day trader status by trading e-mini futures through a futures broker. The PDT rules do not apply in the futures markets. Some of the markets that are available for trading include representatives covering the major indices i.e the YM (DJIA), ES (S&P 500) and NQ (Nasdaq 100) and many more markets; Currencies, Softs, Grains etc.
You can take as many round-turn trades as you care to...as many or as few times a day as you like. E-mini futures contracts trade in sessions with "transition" times between sessions. -- Sessions begin Sunday evenings at 6 PM EST and are open through Monday evening at 5 PM EST...The next session begins at 6 pm Monday night running through Tuesday at 5 PM EST...etc...until Friday's session close at 5 PM EST.
Just as with stocks, you can either buy first then sell (open and close a position) or short-sell (sell first then cover by buying). You profit (or lose) on a round turn trade in the same manor as you would if trading stocks, options, ETFs etc. The e-mini futures are different than the main futures markets that you may have seen traders working in the "pits" in Chicago...E-mini futures are totally electronic (no floor traders) and do not involve any potential delivery of the 'product'...They just require the closing of positions to end a transaction.
A major difference is you need to maintain very little cash in your account in order to trade...$1000 or less per trade, per e-mini contract...You can trade just 1 contract at a time or as many contracts as you have the cash in your account to cover. "Settlement" is immediate upon closing out any position that you may have put on...No waiting for clearing before your next trade. If you want to hold an e-mini contract position over 2 or more sessions, you need to have about $5000 per contract in your account to cover the minimum margin requirement that comes into play during the transition between sessions...
With the e-minis you are speculating on gaining from the difference between when you 'put-on' and "close-out" a position in order to profit. For example, if you think the DJIA is about to rise 20 points, you can buy 1 contract. If you were correct in your assessment and sold your contract after the e-mini rose 20 points, you profited $100. (For the DJIA e-mini, each 1 point 'tick' is valued at $5.00)
