Quote from smilingsynic:
As one who has struggled for most of his life against perfectionistic tendencies, I hear you. Being penny wise and pound foolish is a bad habit: you end up getting filled on all of the losing trades and miss getting filled on too many of the winners. It is wiser to focus more on the exit than on the entry.
What I do to avoid my inclination to perfectionism is to have "buying zones" and "selling zones." If my target sell price is, say, limit 1480, then I will place an alert to start looking for a place to sell if the price comes within 1-2 points of that price. If the alarm goes off because the price comes into the zone, I will watch the screen like a hawk and have a market order ready for the moment.
I rarely get my perfect price that way (sometimes I get a better price). And it is better that way. This afternoon, for instance, I was looking to sell around 1480-2. My alert went off at 1478. I watched the price spike on high volume, watched it go to over 81, and then I sold at 80, when it looked like the buying frenzy had ended.
Did I get my perfect entry? No. But so what? I was in, and now I could focus on the more important aspect--the exit. Once in, my thinking goes like this: If I am wrong because the buying has come back, I am out with a loss; if the buying has dried up, I'll cover for a profit on high negative TICK and high volume.
In the end, the exit was not perfect either (it rarely is). But it was a profitable day. Could have been better, but could have been worse. Unfortunately, the could of's and the should of's cannot be taken to the bank!
