On this review, let me tell you what order flow trading is not. Order Flow Trading is not technical analysis or fundamental analysis, although both of those certainly do play a part in order flow analysis. Why? Because technical and fundamental analysis do not always move the market because they do not always generate the necessary order flow to move the market.
Sometimes they can move the market, and other times they cannot. Technical and fundamental analysis are not the foundation of every market. Order flow and liquidity is the foundation of every market.
Order Flow trading seeks to correct the deficiencies in both technical and fundamental analysis in order to come up with high probability trading based on the very foundations of every market: order flow and liquidity. It's the most profitable way to trade as long as you're willing to learn the art of order flow trading.
