Is a fact the market is often in a range bound condition and this means there is a lot of choice for who want to trade this kind of market, is a fact that a range bound can be also seen in two parallels line in an up and down trend. Is a fact for instance just to mention evidence that SPX before to breaking down on weekly/daily the trend line, was in a perfect channel, an up trending one, and if I see charts empirically looks kind of backtested. Still, I do not see, hear of successful traders that made a fortune on that, there are a lot of explanation of using a stochastically indicator, interpreting the volume as support in the educational materials but I never heard of a successful swing/day trader using them. Is a broken strategy or a well kept secret?
