Methodology
formula v1Each UTC day we compute four scores from the BTC and ETH perpetual futures of every exchange this site tracks. Each maps its input to 0–100 with a fixed scale, so 50 is neutral, and the index is their plain average (at least 3 of the 4 must be available that day).
- Funding: F = the day's open-interest-weighted average funding rate, per 8 hours. Score = 50 + 50 × tanh((F − 0.01%) / 0.02%). 0.01% per 8 h is the rate most exchanges pay when longs and shorts are balanced; 0.03% scores 88, 0% scores 27.
- Open interest change: Δ = BTC + ETH open interest in USD at the end of the day over the end of the day before, minus 1. Score = 50 + 50 × tanh(Δ / 5%). New leverage flowing in reads as greed, positions closing as fear. Because open interest is measured in USD, it also moves with the price: a 5% rally with no new positions reads as +5%.
- Long/short: P = Binance top traders' long share of their positions (BTC and ETH averaged), compared with its own mean over the previous 30 days. Score = 50 + 50 × tanh((P − 30-day mean) / 4 percentage points). Positions rather than account counts, because the crowd's account ratio tends to rise when prices fall.
- Liquidations: Score = 100 × short liquidations / (long + short liquidations), in USD. Shorts are wiped out when the price rises, longs when it falls.
Readings: 0–24 extreme fear, 25–44 fear, 45–55 neutral, 56–75 greed, 76–100 extreme greed (on the rounded value). Today's value is provisional until the day closes at 00:00 UTC. The day that just closed can still shift slightly until about 02:00 UTC, when the hourly rollups replace the 5-minute data it was read from; after that it does not change. Liquidation feeds sample (Binance publishes at most one liquidation per symbol per second), so the liquidation score uses the long/short balance, not the size. All data comes from the exchanges' public APIs.
The history is short, so there is not enough of it to say what any reading has led to. The index describes positioning that already happened; it is not a trading signal and not financial advice.
