I've been getting many PM's asking about my time frames. Instead of replying to all of them, I'll just answer the question here:
I've never really deviated from the standard Schonfeld time frame, which I was taught at the very beginning of my trading career. I scale in and out of big positions in little pieces. The time frame from when I start building up the position until it's completely closed out... is between a couple minutes, up to a few hours. I'd say my average position that does get built up with considerable size, is held for an average of about 1-3 hours.
Smaller trades that I don't build up into big positions are generally held for less time- between about 2-20 minutes, I'd say.
One more thing- I've been thinking about this, and posting my trading results here every single day could easily have a negative effect on my results. <b>Overtrading when I should be light or flat- that's my #1 weakness.</b> Posting my results here every day could easily prompt me to overtrade in order to 'keep things interesting'. On Friday, I probably should have traded under 100,000 shares for a modest profit of $5-10K... but I overtraded a dull choppy market instead. It wasn't a relatively big loss, but it was my biggest drawdown in 7 trading days.
At this point, I intend to post my more interesting up & down days (You haven't seen one yet... ), and keep the ordinary ones to myself.
