Let's assume that the 2 point stop-loss is already set. So in another words, if you are wrong, you'll lose 2 points automatically.
Now, I'm assuming that the entry was random(Something like when I woke up I suddenly had a position and for some reason I can't complain) and the market is going my way at the particular point.
Then I'm going to play it safe by 1. Just getting out. Still, inandlong's point is more on how would you maximize the profits in a situation.
So I'll keep myself safe and exit part of it so that I can reduce the 2 point loss to somewhere better. If it's above 2 move that the moment, even if I get hit with the stop-loss, I can break even. I'll let it ride after that and if I feel the wave has hit the top, I'll take some out also.
Given the situation, that's the most I can do to play it safe and also try to profit out of it.
Still, along the positive open position, if I get an opposite signal, I'll get out, if I get a positive signal, I'll pyramid the remainder of the position I would have traded without the random one.
Let's say we want the best way to trade in a series of random trade. That's a different story.
