Trading can't avoid technical analysis. Over a century of evolution has given rise to eight classic schools of thought, each with its own expertise: Dow Theory: The trend pioneer, the cornerstone of all technical analysis, sets the market's big picture Elliott Wave: Market rhythm, the 5 up and 3 down cycle of 8 waves, deconstructs major market structures Gann Theory: The mysticism of time and space, mathematical resonance between price and time, pinpoints turning points with precision Pattern Analysis: History repeats itself, head and shoulders/top, triangles, flags—read the charts to judge bullish or bearish trends Volume-Price Analysis: The language of capital, trading volume is the footprint of funds, distinguishes real trends from fake ones Indicator Analysis: Mathematical quantification, MACD/RSI/KDJ—use indicators to quantify market conditions Trendline Analysis: Drawing lines to define boundaries, trendlines/support and resistance—use lines to map the market's borders Chan Theory: A local precision structure, fractals/centers/divergence—pinpoint buy and sell opportunities with accuracy
