Updated Cumulative Volume Delta

CumDelta — Cumulative Volume Delta with Session Reset
A clean cumulative volume delta (CVD) indicator that visualizes the running balance of buying vs. selling aggression using lower-timeframe up/down volume. Designed for intraday traders who want to read order flow alongside price.
What it does
Each bar's delta is calculated by pulling lower-timeframe volume data and classifying it as buying or selling pressure based on whether each sub-bar closed up or down. These per-bar deltas are then cumulated into a running total that resets on your chosen schedule (day, session, week, month, year, or N bars back).
The cumulative delta is rendered as candles — each candle's open chains from the previous close, and the body shows whether net flow on that bar was positive or negative. A histogram below shows the raw per-bar delta for quick reference.
How to read it
Rising green candles — sustained buying pressure
Falling red candles — sustained selling pressure
Divergence vs. price — price makes a new high but CVD doesn't (or vice versa) often precedes reversals
Reset bars (optional yellow highlight) — fresh session start, useful for marking where the cumulation restarts
Settings
Reset Period — Day, Session (RTH-aware), Week, Month, Year, or Bars Back
Lower Timeframe — auto-selects based on chart TF, or set manually for finer/coarser resolution
Doji Handling — choose how to attribute volume when a bar closes flat (Split 50/50, Up, Down, or Skip)
Display toggles — bar delta histogram, cumulative candles, reset markers
