"He found that he could bump up the price with very small trades and then sell with much larger trades for a profit. He was not the only trader who worked out this flaw, which he called “painfully obvious”. But he still made $50,000 (U.S.) in a few months."
and some people claim edges don't exist!
that's the key - to UNDERSTAND what's really going on and if possible to take advantage of the situation.. indicators, divergences, trend lines are better left to the brainless ones / if they ever win it's because of their money management approach as the entries are more or less random imo/ ..

Unfortunately for most / me included
/ brain work , probably lots of it is required..
