I've been working on a short term (seconds to minutes holding)trading system on the ES and YM. The entry is hard, but the exit is making my brain go numb. Seriously. Figuring out resonable profit & stop loss targets is very difficult. Do I use a fixed amount? Do I adjust the levels as the market moves (and is that even possible with such short holding periods)? How tight do I make the stops so I don't get stopped out too quickly? How high is too high a profit limit that I'm now trading a longer trend that will fade to my stop before being reaching my limit? You guys know all these questions and I'm sure have some bald spots, grey hairs and sleepless nights trying to figure them out. I'm not asking for any big gifts, but any rules of thumb or advice will be appreciated. I'll even take all the regular platitudes. Anything! Thanks a lot. I really appreciate all the people here very much.
