Definition: Trading volume in futures and spot markets often differs considerably. Futures volume includes substantial leveraged turnover, so the volume in the two markets does not mean exactly the same thing.
A common way to read it: After a volume spike, if volume quickly falls back, the spike was probably just a brief burst. Sustained higher volume is more meaningful.
Don’t chase a trade during the fastest part of a price swing. Wait for the price move to play out before deciding.
