Candidates

Symbols whose smoothed 21-day put/call moving average changed regime within the selected recency window.

Show turns in last N days

Signal smoothing

Minimum turn

Signals run on a smoothed 21-day MA (a moving average of the 21-day average). Signal smoothing sets how many sessions that smoothing spans, Minimum turn is how far the smoothed line must travel since the turn, and Show turns in last N days keeps only turns that happened recently. A turn also has to reverse the prior regime, so an up-tick inside an already-rising trend is ignored. Click any candidate row (or focus it and press Enter) to load that symbol into the charts above, and click Sym, Ratio, Turn or Move in a table header to sort that table (click again to reverse it).

Buy candidates

The smoothed 21-day average rolled over after rising — fear has likely peaked.

Sell candidates

The smoothed 21-day average turned up after falling — hedging is picking up.

How the Put/Call Ratio Tracker works

The put/call ratio compares the daily option volume of puts (bets that a stock will fall) against calls (bets that it will rise). Tracked over time, it becomes one of the cleanest read-outs of crowd sentiment in the options market. This dashboard collects a daily snapshot for each symbol and overlays a 21-day moving average so you can see where today's reading sits relative to the recent trend.

The ratio is most useful as a contrarian sentiment indicator. Persistently low average ratios mean traders are heavily skewed toward calls — a sign of complacency or greed, and often a market that has run ahead of itself. Persistently high average ratios mean traders are loading up on puts — a sign of fear, capitulation, or hedging, which historically has marked attractive entry points rather than the moment to sell. Extremes in either direction tend to mean-revert.
