What is Volume?
Volume is the total quantity of shares (or contracts, for F&O) that changed hands during a given bar. It has no single inventor — it has been plotted alongside price for as long as exchanges have published trade tickets. On the NixPulse chart it is a histogram beneath the price pane, tinted green or red depending on whether that bar's close was higher or lower than the previous close.
Formula
Volume(bar) = total quantity traded during that bar's interval
Close>PrevClose -> up color; Close<PrevClose -> down colorParameters
| Parameter | Default | Description |
|---|---|---|
| Up/Down coloring | On | Colors each bar by direction of that bar's close vs prior close |
| MA overlay (optional) | Off | Some platforms overlay a simple moving average of volume |
Signal Interpretation
- Rising volume on a breakout adds conviction that the move is backed by real participation.
- Rising price on falling volume is a classic warning sign of a weak advance.
- Volume spikes at turning points often mark exhaustion of the prevailing move.
- Very low volume during a rally or selloff suggests the move can reverse easily.
- Volume tends to expand near the open/close and contract around the midday lull.
Tips & Best Practices
- Always read volume relative to its own recent average, not as an absolute number.
- Use volume to confirm, not predict — it validates a move that has already started.
- Combine with price-action context since volume alone rarely gives a standalone signal.
