Quote from Tech Analysis:
In my first year I was stroking my ego with 65-70% winners. Problem was, I'd book a winner - ANY winner - even 5 bucks, just to keep the winning percentage high and book a "winning trade". For every 5.00 winner, though, I had 20.00 losers.
Screw the win:loss ratios; keep your gain:loss ratios in check and you'll suceed.
Real life stats from my years trading at a big prop firm that tracked every imaginable statistic tells the story pretty much the way Tech Analysis summed up his own experience.
As for what Harry said, maybe someone can explain it to me (This is NOT a request

).
Anyway, the guys that made the most money did generally not have outstanding winning percentages. They got out of losers quickly and often. (And frequently they soon got back into the very positions in which they had already booked losses). Rather than worry about their small losses, and rather than get into "wish and pray" mode, they just got out.
Trading is not baseball. Batting average is nice. But RBI's and runs scored are what matters. Even batting average can be misleading. In the NL, come to the plate with 2 out and the pitcher on deck, and it is unlikely you will not get something to take a whack at. Helps the average, but is unlikely to add up to big numbers that affect the outcome of too many games. Drop the same eighth place hitter to the middle of the lineup, and unless the manager was wrong about him all along, down goes his BA. (Here, maybe Harry can use an explanation

)
It always seems to come back to "cut your losses, and let your winners run". This does not tend to help raise the average number of wins. It does, however, raise the
average dollar per share, which is the only number that matters.
(An exception for Nitro....since he seems to predominantly scalp the minis..they always move....different style. So trading futures, or ETF's is a bit of a different story, and was not included in any of the studies I got to see).
Peace,
