scaling out is how i get around the "selling the winners too early" vs. the "letting a winner turn into a loser" paradox.
simply put, take profits at logical points and then use a trailing stop to stay in as long as possible on your last lot
it's not perfect, but it works well for my methodology. smooths my equity curve, frequnetly keeps me in for larger moves (but not wiht optimal size) etc.
it's called trading, and it's frequently about tradeoffs
today for example, i bot corn (mar 07) at 372 372 1/2 372 3/4 (4 contracts total)
i scaled out the first 3 contracts as it rose, with limit orders
but i managed to save the last contract and am still in
im normally a scalper, but if the action keeps me in the trade, that's fine
i woul dhave made WAY more money if i held all 4 contracts to 378, but i had no idea of knowing it would move this far
