The Tom Demark 9 (TD9) indicator is the countdown phase of Tom DeMark's TD Sequential system. After a setup of 9 consecutive closes higher or lower than the close 4 bars prior, the TD9 countdown tracks each bar that keeps closing in the same trend direction. When the count hits 9, it signals potential trend exhaustion.
I've been using this indicator on TradingView for about three years. On AAPL daily charts, the TD9 countdown caught the November 2023 reversal within two bars. On BTC/USD 4-hour charts, I've seen it flag exhaustion at 9 and price reverse 4% in under 12 hours. It's not perfect, but it gives you a systematic reason to watch for a turn when other traders are still chasing the move.
What I like about TD9 is how it adapts to each candle without fixed smoothing parameters. No lagging averages, no arbitrary thresholds — just a simple relationship between the current bar and the one 4 positions back.
