When talking about trend following, it's hard not to look at chart. Of course, trend following is about longer holding period, months if not years. Here is the S&P 500 from 2017 to 2022. As with any strategy, it does not work all the time. Drawdown is a bitch in this game.
Drawdowns cannot be avoided in trading. However, if you trade both sides of the stockmarket by going long when it is up trending and shorting it when it is going down, you probably, can reduce the effects of drawdowns.

I dont blame him @ all for not liking DOW [DIA......]much; but actually SDOW, DOW+ DIA tends to move different from ES, SPY,SPXL,QQQ...... I dont trade ES anymore but my points still apply. Counter trends tend not to do as well; but have an added benefit of helping you not meddle with a profitable trend or reasonable probability of main trend staying profitable..............
