Same-instant trade count
Updated
What is Same-instant trade count?
Same-instant trade count is a market-data metric BlackForge measures for every listed pair on nine spot exchanges, once per closed five-minute window. Trades sharing the same millisecond timestamp in clusters of three or more. It reports what the order book or trade tape showed, not what price will do next.
