Outcomes use only the spikes in the live list, not every spike in the 24h total. They fill in 5, 15 and 60 minutes after each spike, measured from the spike minute's close on the same market. A dash means pending or unavailable; n counts measured outcomes, including zero moves. Small samples are noisy, and past moves are not a prediction.

About the SP500 volume spikes
What is a SP500 volume spike?
A minute in which one SP500 market (spot or perp, on Hyperliquid) trades at least 4× its normal minute volume, where normal is the median of the previous hour, with a size floor ($30K spot, $75K perps) so thin trading doesn't count.
How to read it
Buy % is the share of taker buys in the minute: 60% or more is a buy-side spike, 40% or less sell-side. The +5m / +15m / +1h columns show what price did afterwards on the same market, and the table above averages them. Spikes at the same time on several exchanges carry more weight than one venue alone.
Is this a trading signal?
No. It is a record of unusual activity and what followed. Averages over a handful of spikes are noisy, and the list only holds the most recent spikes. Not financial advice. See live spikes for every coin.
