Quote from NoDoji:
PA, after months of testing averaging vs exiting and re-entering at a better price in my demo account, here is the result:
Averaging "feels" better because you don't have to realize a loss, therefore as long as it works, you are always right. You can average into a loser until you have a $5K drawdown, then if all works out "as usual" you get out of the trade eventually for a $120 gain sighing with relief. But it was a winner! So you were RIGHT!
Exiting for a small loss when the trade runs against you, then looking to re-enter at a better price requires focus, patience and solid skills at reading price action. You may get in on what appears to be a good setup, then price reverses and stops you out for a (gasp!) loss. You have a choice then to reverse your position or if you feel that the bigger move will eventually be in the direction you initially chose, you can wait patiently for a better price and good price action setup.
This is the method that produced much larger net gains in my sim account when I was patient and stayed focused.
I say net gains, because although the averaging strategy worked 90% of the time, the 10% of the time it failed badly wiped out a large chunk of the previous gains.
