Technical Analysis (TA) is the study of past price and volume data to predict future price movements. It's based on three core assumptions: (1) The market discounts everything — all known information is already reflected in the price, (2) Prices move in trends — uptrends, downtrends, and sideways trends, (3) History tends to repeat itself — because human psychology (greed and fear) doesn't change. Unlike fundamental analysis which asks 'what to buy', technical analysis answers 'when to buy and sell'.
Key points
Pro tip — Don't try to learn every indicator and pattern at once. Master these 4 things first: (1) Candlestick patterns, (2) Support & Resistance, (3) Trend lines, (4) Volume analysis. These alone can make you consistently profitable. Everything else is secondary.
