Position size is NOT an edge. Money management rules do not make an edge.
An edge exists where and when the probability of one immediate outcome is more likely than a different outcome,
and the opportunity exists to make a bet and possibly profit should the odds play out in your favor.
In trading, for example, when the NDX and SP-500 both gap open up, and then the respective futures both try to fill the gap on an initial move lower that reverses higher without filling the gap in the first 30 minutes of the NYC open, the
probability that the market will trend higher and close at its high is
magnitudes higher than the odds that it will reverse and fill the gap. The edge therefore belongs to the long side player.
He has the best of it. Anyone betting short on such a day is betting the dog.
He has the worst of it. And for those who understand the notion of
pressing a bet - that is precisely when one would bet larger than if one were playing an even money or slight edge. I have a usual trade size. I don't take low odds plays, so I never
reduce from that size. But there are times where
I go gonzo - when the opportunity and likelihood of getting on the right side of the move is
so outsized that trading it normal size would be
foolish, imo. That is the benefit of having a
real edge. That is the benefit that comes from observing, and noting patterns of price behavior, and back testing, and forward testing, and then trading.
You are simply repeating some garbage you read from some other guy who failed as a trader. You have no idea what an edge is. You are just hoping that your 2% bet scheme will keep in the game long enough to actually figure this out. And since I've been trading, I have never had a drawdown in points close to what you have open on your current ES trade. My largest drawdown over a
series of trades in the NQ has been 29
ticks or $145/contract - and I was green green green at the time. And that was over three trades, not one. So dude, seriously, you have some real credibility issues coming around here and seeking to school us on what is and is not an
edge.
