0:00Welcome back. ADX and the directional movement index — the tool that tells you whether to trend-trade or stand aside. ADX measures trend strength on a zero-to-one-hundred scale, and crucially, not direction. Above twenty-five, a real trend is underway and trend-following works. Below twenty, the market is ranging and breakouts will fail. The two D M I lines, plus and minus, tell you direction: when plus is on top, buyers control; when minus leads, sellers do. ADX says how strong, D M I says which way.

0:33Only trend-trade when ADX confirms strength, and let the D M I lines pick the side. Next: Parabolic SAR.

Indicator Pitfalls: Lag, False Signals, and Repainting

Indicators don't lie about the past — they lie about the future, and each one does it in a specific, math-driven way. This episode breaks down the three failure modes you can't optimize away: lag (a 50 SMA trails by ~25 bars), false signals (MACD whipsaws in range), and repainting (ZigZag, Ichimoku spans, and unclosed-bar crossovers that vanish by the close).
