Definition
Technical analysis, or TA, focuses on observed market activity rather than directly valuing a project’s business or protocol. Traders use trends, support and resistance, chart patterns, and mathematical indicators to organize decisions. These tools express interpretations of past and current data, not certainty about future prices.
How It Works
For example, a moving average can smooth a noisy price series to make its recent direction easier to see. A proposed rule might combine a price breakout with a volume condition, then specify the entry, exit, position size, and circumstances that invalidate the idea. This is more testable than labeling a chart bullish after the move has happened.
Historical testing should account for trading fees, slippage, and whether the information was actually available at the decision time. Evaluating untouched data helps reveal rules that merely fit one historical sample.
Key Considerations
Indicators built from similar inputs may repeat the same information rather than provide independent confirmation. News, thin liquidity, and changing market conditions can invalidate patterns. TA does not establish an asset’s intrinsic value or guarantee profitable execution. Its usefulness depends on clear rules, realistic testing, and disciplined risk limits.
