0:00Welcome back. The money flow index — think of it as RSI with volume baked in. MFI runs the same overbought-oversold logic as RSI, but it weights each move by volume. So an extreme reading backed by heavy volume carries far more conviction than one on thin trade. Over eighty is overbought, under twenty oversold. And like RSI, the best signal is divergence — but here, divergence means smart money is quietly moving against the crowd while volume tells the real story.

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).
