Index of Lowest Value (ILV) Indicator
The Stopwatch That Ages the Market's Recent Lows
While traders love knowing *how low* price has dropped (Lowest Low Value), the Index of Lowest Value (ILV) reveals something even more valuable: *how long ago* that low happened. It outputs a simple integer (0 to Nā1) counting bars since the most recent low within your look-back window. Zero means 'fresh low today ā downside alive!' while higher numbers show the low aging. It's the perfect timing tool for short breakouts, exit rules, and spotting when bearish momentum is running out of steam ā adding the critical 'freshness' dimension to support levels.
The Straightforward Formula
Clean logic:
ILV_t = N - 1 - \text{index of min}(P_{t-N+1 \to t})
Where index 0 = oldest, Nā1 = current bar.
0 if current bar is the low, Nā1 if oldest bar still holds it.
Interpreting the Age Counter
What the number signals:
- 0: Fresh low today ā downside momentum strong.
- 1ā3: Low very recent ā bearish trend healthy.
- ā N/2: Low aging ā possible exhaustion building.
- > N/2: Low getting stale ā sellers weakening.
- Nā1: Oldest bar holds low ā reset imminent, potential bullish trigger.
Parameter Choices
N defines the scope:
- Short (5ā10): Sensitive ā intraday micro lows.
- Medium (20ā50): Balanced ā daily swing freshness.
- Long (100ā252): Macro ā 52-week low age tracking.
Pro Trading Applications
Smart uses:
- Fresh breakdowns: Short only when ILV = 0 ā true new low.
- Trailing exits: Close shorts if ILV > threshold (e.g., 10) ā no new low too long.
- Mean reversion: High ILV = old low ā fade dips in ranges.
- Volatility timing: ILV on ATR nearing N ā compression, prep expansion.
Mirror of IHV ā together they time-stamp both extremes.
Strategy Templates
Quick setups:
- Fresh downside: Short when price < LLV and ILV = 0.
- Pullback defense: Stay short if ILV ā¤ 5 ā recent low confirms pressure.
- Volatility squeeze: ILV on ATR high ā low vol, breakout looming.
Strengths and Limitations
The Wins
- Instant age of low ā zero lag freshness check.
- Versatile on any series.
- Great for exits and filtering stale downside.
- Simple timing enhancer.
The Gotchas
- Flips on spike lows ā filter needed.
- Descriptive ā pair with rules for action.
- Oscillates in tight ranges.
- No magnitude ā use with LLV.
Your ILV Launch Checklist
- Choose series (Low common) and N.
- Plot with LLV for context.
- Backtest age thresholds for entries/exits.
- Combine with trend/volume confirmation.
- Alert on ILV = 0 or stale values.
- Review N across volatility regimes.
Key Takeaways
ILV counts bars since recent low ā downside freshness meter.
0 = new low today, high values = stale bearish momentum.
Perfect for fresh breakdowns, trailing exits, and spotting exhaustion.
Adds time dimension to support levels.
Simple but insightful ā know when your low is alive or history. Stay timed and trade strong!
