I find posts like this interesting. First of all, from my foggy memory, I do think I like most of what you post and unless I'm wrong, you are a profitable trader. So assuming this, I have to also believe what you say about the ES being dead in this environment.
But when I look at the ES, I see typically at least a 10 point range during RTH that bounces off fairly often from key levels. (today of course is just a fluke given how perfectly the previous day high and low worked). I would assume that a day trader is targeting 3-4 points, or even a little less, and then using stops that are hopefully not more than 2 points.
Clearly if a strategy requires 15 point targets and 5 point stops, it can get very difficult because you never hit your target, and after 1 stopout, it very hard to make your money back. But given what you say, then it must mean that the day traders you are thinking about need these type of stops and targets. The reason I find this interesting is because I consider a 4 or even 5 point stop huge.
To me, having to use a stop like this means that you really don't know where the market will turn, and that you are giving it too much room work work. I see posts on the ES journal thread where guys are just blindly adding to losing trades, averaging down and hoping to get rescued, but this certainly isn't a sound strategy in my opinion. (at least not for the day trader)
Anyway, maybe its a bit too cocky or me to say, but I think that if a trader was killing it when the moves were much bigger, it shouldn't be too hard to adapt for the current environment. When you know the daily range is much less, your stops can also be much less, and likewise, your targets have to be less as well. Perhaps its not worth it to some traders, but if a trader was only doing well in high volatility, I wonder if they were trading, or just getting lucky by jumping on a move and hoping for it to continue. The statistical nature of the markets with regards to average win, average loss, win rate, that sort stuff doesn't change. The numbers change of course, but the nature of win some, lose some, try again, that is all the same.
