I began trading options precisely because they seemed particularly suited to a small account, especially within the context of IB's commission schedule which is unbeaten by any other retail broker.
At IB you can buy a single contract at say $1.00, or even less, thus spending $101.00 for contract + commission. There is no margin involved. The absolute maximum a small account trader has risked in this example is $101. Absolute maximum loss $101.
I don't see why that is considered an inadvisable method for a small account trader. The idea of selling a stock short always seemed far more inadvisable, considering that if the stock goes up the potential for loss is theoretically nearly infinite. (Although it really isn't, because IB will auto-liquidate, which in general is a pretty good thing, although of course occasionally it isn't). The small options trader has limited his potential loss by avoiding using any margin. I don't see why that isn't the wiser approach. Except for the damned Time Decay of options. But it is precisely because of the Time Decay that options ideally should be held for as short a time as possible. In other words, if you can get in and out of the option in the same day with a profit of any amount, really that's the best way to handle options. So, with options daytrading is in fact what any small trader should really be aiming for.
And this was not a problem before October 15, 2002.
Well, ok, anyhow having said that a small account can in fact daytrade single options contracts at IB without the PDT restrictions, if it is a cash account, which I myself did open in November for this reason. A cash account like that is restricted in how much you can trade, in that you can only use the amount of cash within your account one time on any given day, because you need to wait for one-day settlement before the cash paid to you arrives in your account.
