You talk about averages here, but once again, as you even pointed out, averages mean nothing, its the distribution. My point is that is a day has a range of 10 points, and you're using a 3 point stop, this means that your stop covers 30% of the daily range. Its kind of like saying you can guess a person's weight, who appears to be about 200lbs pounds, and yet give a margin of error of 30%, so this means that if you say 200lbs, and they end up being just over 140lbs, you would still consider this to be a good guess since you were within 30% of the 200lbs guess. Do you follow?
A 3 point stop, if your testing shows this, is totally fine, but this means you're not nailing your entries as perfectly as you appear to claim. Furthermore, if you enter, and your trade comes close to stopping out, but you close it out for a couple of ticks profits, do you count this in your 80% win rate just because it was closed at a profit? Don't get me wrong, this is good trade management, but this certainly once again doesn't exactly fall in like with your initial stat of 80% wins with an average of 5 points.
I'm not sure why you didn't address my liquidity points because they are absolutely valid. I simply don't believe that as a retail trader, your account could be in any way liquidity limited in the ES unless all your entries happen during a volatility spike and there simply aren't that many contracts traded at one level. The fact that you know that a 3 point stop works best for you, this means that often the trade does go a few ticks against you, which means that you could add to your position for an even better price.
My beef is that what you say isn't exactly where the truth is. You purposefully leave things out, which of course is totally fine given the anonymity of the internet, but by doing so, you're giving the wrong impression, which isn't helpful to the trading community if what you want to do is be honest and helpful to this community. Of course if you have other intentions then continue as you are, but the fact that you're so secretive about details with reference to stats and such means there is more to the story than an 80% win rate and 5 to 1 profit.
