I am not disagreeing but I want to point out that as the time period gets shorter then what happens at any time point may approach 50:50, but as the time period between points gets longer my experience is that there is a definite bias for the market to do at the next point what it did at the last point, i.e., go up, down, or sideways.
Traders like to say at every point it's 50:50, but a little consideration of this statement would suggest that averaged over time the market would then move sideways, neither up nor down. Due to inflation alone, markets will over long time periods trend up. Markets over longer periods are not random but show pronounced tendencies to move sideways, up, or down. If what I write is correct, it tells us that traders basing their trades on price alone may do better using longer time frame bars. There are other things in addition to price, of course, that traders may base their trades on.
