even if following the trend, i reckon unless one is looking to get in right at the breakout or breakdown point, then they will almost always be countertrending the smaller time frame to get into their positions.
like i will buy the pullbacks on uptrends and sell the rallys on downtrends. if i have determined an uptrend by the 5 minute charts then i will look to buy at some point that will most usually FEEL like i am fighting the trend and will almost always look like an authentic trend reversal on the 1 minute chart. as this is a psyche forum, the "feeling" is usually engendered by thoughts like "clearly it is moving in this direction so why the f..k are you playing the opposite?!" or "surely this is a trend reversal and not just a pullback" or "however much you may have backtested, this is one of those days that it just doesn't follow those ever ambiguous rules or it's the beginning of the end of this vehicle's behavioral patterns" etc. etc. etc.
why fight the trend? like NihabaAshi had said, i don't think anyone would intentionally do it and it all depends upon the time frame used. like if you are more into holding long term, it seems that the monthly or even weekly ES or YM charts are still bearish and they may be taking a breather before resuming their downward plunge. for me, i wouldn't put too much money in either direction long term thus i am one of those chickeny types that if not fairly market neutral, am out of my positions by the end of the day.
