Volume Per Second shows how fast volume is coming in, by dividing each bar's volume by its duration in seconds. Because the value is "volume per second", it can be compared directly across all timeframes. How it works • Closed bars: volume ÷ full period length (e.g. 60 s on M1, 900 s on M15, 3600 s on H1) • Current bar: volume ÷ seconds elapsed since the bar opened, refreshed every second even when no new ticks arrive • Warm-up smoothing: in the first part of a new bar, the seconds that have
