Premarket&Regular Session Volume

This script provides a clean and practical overview of premarket cumulative volume compared with regular session volume, helping traders instantly identify unusual early-session liquidity.
Features
Tracks total premarket volume from 4:00–9:30 ET
Shows cumulative premarket buildup as a smooth line
Helps detect early liquidity spikes that often lead to halts, gap-ups or momentum runs

Why It’s Useful
Premarket activity frequently reveals hidden demand long before the opening bell.
When premarket volume significantly exceeds average daily levels, the probability of early spikes, volatility events, or continuation moves increases.
