Hmmm. In my real account I don't have enough $$$ to comfortably trade more than 1 YM contract with a 10 point stop.
Just for grins I've been paper trading like volente does. 2 contracts, 20 point stop. At 10 point profit, sell 1 and set stop to BE.
So far, 3 trades, 3 wins.
Trade 1:
Buy 2 at 10405
Sell 1 at 10415,MFE=10,Net Profit=45.2
Sell 1 at 10405,MFE=12,Net Profit=-4.8
MAE=6
Trade 2:
Buy 2 at 10401
Sell 1 at 10411,MFE=10,Net Profit=45.2
Sell 1 at 10403,MFE=12,Net Profit=5.2
MAE=17
Trade 3:
Buy 2 at 10430
Sell 1 at 10440,MFE=10,Net Profit=45.2
Sell 1 at 10435,MFE=15,Net Profit=20.2
MAE=4
As you can see, Trade #2 was a real nail-biter with an MAE almost to my original 20 point stop.
