Market Breadth
How much of the market is participating—not just what the index is doing.
Time Machine
Beginner's guide
1. Start with today
The ±4% counts show immediate buying and selling pressure. A large gap indicates broad participation; similar counts mean a two-sided, mixed session.
2. Check persistence
The 5- and 10-day ratios total up-4% events and divide them by down-4% events. Above 1 favors buying pressure; below 1 favors selling pressure.
3. Confirm the regime
Quarter, month and 34-day counts show whether momentum is widespread. T2108 is the percentage of stocks above their 40-day moving average. Read multiple measures together.
