Actually more like "reading the same indicators and patterns". If they can understand the intention (language) behind the last 100+ candles based on chaos theory like vector interpolation, frequency shifting, etc, that would be a different kind of speculation. (Won't call gambling because their risk is managed and isolated per trade and has some statistical edge, but the problem is the commission). But I doubt how many traders have balls to gig that level of the rabbit hole learning Euclidean space, linear dependence variables, Hamilton theorem, Axis of conical rotation, etc just to trade some charts. Retail traders are more interested to find locations to draw random lines that confirm their bias xD
