Quote from logic_man:
Define "start".
If the ES is going to go down 10 points, ultimately, and I get in after 3 of those points have already occurred, is that me getting in at the "start"? And even if I got in 7 points after the turn and captured only 2 points of the 10, if I can do that consistently, there is no end to the amount of money I can make. Do you disagree? If the OP can't do that, it's because he's got a bad system, not that the idea of attempting to do that is a bad idea.
Also, why would you not wait for a confirmation (however you define it) before entering a trade? That doesn't, of necessity, lead to "chasing price". In fact, by requiring confirmation, you do less trading and by passing on potential entries, you are actually doing the opposite of "chasing price" by simply remaining on the sidelines when confirmations aren't present. All systems rely on confirmations at some level. Obviously, the best systems are the ones which combine high accuracy of confirmations with timing as close to the actual reversal as possible. In the ES example above, maybe someone else could have a system which only required a 2 point move as its confirmation. I'm highly skeptical that there is any working system which can do away with confirmations, though, although I would guess there are nearly an infinite number of systems which don't work and which also don't have confirmations built into them.
If you look at the number of points in hourly fluctuation in the ES over a month, it numbers in the thousands (taking the hourly high and the hourly low and just adding the absolute values up). If you can catch even 1-2% of those fluctuations, you will absolutely rake in more money than you can spend. In that context, it doesn't make a lot of sense to try to catch the top or bottom ticks of a trend. In fact, I would state that, as a rule, the more you try to do this, the lower your accuracy will be.
