Volume Ignition Oscillator
Volume Ignition Oscillator (VIO)
Volume Ignition Oscillator flags potential exhaustion points after a sharp price move by combining three conditions: a recent large price swing, price sitting at a range extreme, and volume running hot relative to its recent average. When all three line up, the oscillator "ignites" — hence the name.
How it works
Big Move Detection — the script measures the price change over a lookback window (default 5 bars) against a multiple of ATR (default 2x, 14-period ATR). A move that clears this threshold opens a "watch window" of N bars (default 8) during which the indicator is active — up-moves open a top watch, down-moves open a bottom watch.
Range Position — price's position within the recent high/low range (default 20 bars) is calculated as a 0–1 value. The oscillator only engages when price is in the top zone (default ≥75%) during a top watch, or the bottom zone (default ≤25%) during a bottom watch.
Volume Surge — current volume is compared to its moving average (default 20-period SMA). The excess volume above that average scales the signal — the more volume expands beyond normal, the stronger the reading.
These three factors combine into a raw oscillator value, which is then EMA-smoothed. A slower EMA of the oscillator acts as a signal line.
Reading the indicator
Columns above zero (shaded toward red) = potential topping pressure: a big up-move, price near the highs, and volume ignition.
Columns below zero (shaded toward teal/green) = potential bottoming pressure: a big down-move, price near the lows, and volume ignition.
Column brightness/gradient scales with the strength of the current reading relative to the last 100 bars.
Background shading shows when a watch window is active and fades out as the window expires.
Triangle markers print when the oscillator crosses the signal threshold (default ±0.15): a down-triangle at the top signals possible short/exhaustion, an up-triangle at the bottom signals possible long/exhaustion.
Info panel (top-right, optional) shows the live oscillator value, volume ratio, range position %, and current watch zone.
Suggested use
VIO is designed as a mean-reversion / exhaustion tool, not a trend-following signal. It's best used to:
Spot potential climax moves after an extended impulsive swing on rising volume
Time partial profit-taking or tightened stops on existing trend positions
Screen for reversal candidates that can then be confirmed with price action, support/resistance, or another momentum tool
It is not intended as a standalone entry system — combine it with your own risk management and confirmation criteria. Like any exhaustion/reversal tool, it can trigger repeatedly during strong sustained trends, so treat signals as alerts to watch price action rather than automatic trade triggers.
Inputs
Big Move Detection — lookback bars, ATR length, move threshold (x ATR), post-move watch window length
Volume — volume moving average length
Range Position — range lookback, top/bottom zone thresholds
Signal — oscillator smoothing length, signal trigger level
Appearance — top/bottom colors, toggle for the info panel
Alerts
Two alert conditions are built in:
VIO Short Signal — fires on a top exhaustion cross
VIO Long Signal — fires on a bottom exhaustion cross
