OK, so what could that pre-requisite be?
a) Knowing how the market operates. It's just a market of buyers and sellers, right? With market makers, and the like, acting as intermediaries.
b) Knowing what causes price to go up and down. It's just supply and demand, right? Price rises when the combined $value of all the buy orders exceeds the $value of all the sell orders. And vice versa for price falls.
c) Knowing about the market participants. Large institutions probably account for most of the volume, and most of the price movement, right? Retail traders are probably tiny in comparison, and barely even register on the chart.
d) Knowing what prompts the large players (market movers) to buy and sell. Sometimes it could be an obvious news event. Other times they may be portfolio rebalancing. Or who knows?
Maybe there are telltale signs (clues) on the chart when large players are accumulating or offloading. You can't frontrun them but maybe you could ride their coattails?
