FAQ

Where does the data come from?
Directly from WebSocket streams of three exchanges: Binance, MEXC, and Bybit. The server receives every trade as it happens, aggregates data every 250 ms, and instantly delivers updates to your browser via WebSocket.
How fresh is the data?
Latency from exchange to screen is a fraction of a second. This is not a delayed feed or a once-per-minute API poll — every trade reaches the screener almost instantly.
What is a volume spike?
A signal triggered when trading volume for a selected period sharply exceeds the historical average. The higher the multiplier, the stronger the anomaly.
What is the difference between Watchlist, All Coins, Volume Spike, and Price Change?
Watchlist — coins you added to favorites: always visible regardless of filters. All Coins — all other active pairs that passed the minimum activity threshold. Volume Spike — coins whose trading volume currently sharply exceeds the historical average. Price Change — coins with the largest % price movement over the selected timeframe.
Can I customize the filters?
Yes. In settings: timeframe and % price change threshold, minimum daily pair volume, averaging period and multiplier for spikes, activity threshold for the all-coins block. All parameters apply without page reload.
Why is a coin missing from the tables?
Current volume or activity is below the set thresholds, or there are temporary disruptions in the data stream from the exchanges.
Is registration required?
No. The screener works without an account. Registration enables server-side settings sync and watchlist sharing across devices — but it is not required to use the screener.
Is this investment advice?
No. RanVol is an informational tool that shows market activity as-is. All trading decisions are yours alone and at your own risk.
