I don't always have 25K in my trading account, so I either trade futures (equity index or currency), or I trade options.
Options work well, as you can always sell something else to partially hedge your position.
For example:
Say you're long the Dec $25 call on Acme Explosives. You want to liquidate the position, but can't afford another "day" trade. Rather than selling the long call, you can either sell short the Nov $25 call or the Dec $27.5 call.
It's not a perfect hedge, but the Nov $25 will be pretty close.
Another method is to play both sides: buy the $25 call (hopefully when the stock is rising), then buy the $30 put (hopefully at a point where you're "up" already on the call). Once you're locked into both sides, you can then wait and see what the market wants to do. Sometimes I'll sell the winner at some point and keep the loser looking for a reversal. This time of the month, within 2 weeks of expiration, I start looking to be long the next month contracts and sell short the current month contracts to take advantage of the rapid decay.
This is essentially how I now trade options (having learned the hard lessons of naked leverage). I will let my position be exposed for brief times when I've got a winner going, but I like to hedge it overnight or if I can't watch it live. That way, a black swan event is not an account wrecker for me.
My profits are more consistent, if not downright boring, but it's nice to be able to walk away from the screen without the tension of holding a position vulnerable to an adverse market movement.
Best of luck to you.
