USDa Market PressureEvidence, not a forecast.

Start with zero weighted points. Each rule below adds independently; the final reading is 50 + 8 × points, limited to 0–100.

• One-hour change: more than +3% adds 3 points; more than +2% through +3% adds 2. Changes below −3% subtract 3; below −2% through −3% subtract 2.
• Acceleration: a one-hour change above +1% combined with a daily change above +2% adds 2 points. Below −1% and −2%, respectively, subtracts 2.
• Daily change: above +5% adds 2; above +2% through +5% adds 1. Below −5% subtracts 2; below −2% through −5% subtracts 1.
• Weekly change: above +10% adds 2; above +3% through +10% adds 1. Below −10% subtracts 2; below −3% through −10% subtracts 1.
• Range position: above 85% of the reported daily range with an hourly change above +0.5% adds 2. Below 15% with an hourly change below −0.5% subtracts 2.
• Volume intensity: reported volume divided by market cap, multiplied by 100. Above 30%, an hourly change above +1% adds 1; below −1% subtracts 1.

Each threshold is strict. Inputs are aggregated CoinGecko observations, not executed buyer/seller flow. A 50 score can represent weak signals or offsetting inputs. The model is not a probability or a recommendation.

Collection runs approximately every five minutes. Provider observations up to 15 minutes old are marked fresh; older observations are marked stale and are hidden after six hours. “Fresh” does not mean tick-by-tick. History records at most one fresh observation per 15-minute interval, retains 90 days, and displays up to 30 days here. It starts with collection, not reconstructed past readings.
