The 90-second answer
The technician believes that anything that can possibly affect the price—fundamentally, politically, psychologically, or otherwise—is actually reflected in the price of that market.

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 N−1) counting bars since the most recent low within your look-back window. Zero means ‘fresh low today – 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 – 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, N−1 = current bar.

0 if current bar is the low, N−1 if oldest bar still holds it.

Interpreting the Age Counter

What the number signals:

  • 0: Fresh low today – downside momentum strong.
  • 1–3: Low very recent – bearish trend healthy.
  • ≈ N/2: Low aging – possible exhaustion building.
  • > N/2: Low getting stale – sellers weakening.
  • N−1: Oldest bar holds low – reset imminent, potential bullish trigger.

Parameter Choices

N defines the scope:

  • Short (5–10): Sensitive – intraday micro lows.
  • Medium (20–50): Balanced – daily swing freshness.
  • Long (100–252): Macro – 52-week low age tracking.

Pro Trading Applications

Smart uses:

  • Fresh breakdowns: Short only when ILV = 0 – true new low.
  • Trailing exits: Close shorts if ILV > threshold (e.g., 10) – no new low too long.
  • Mean reversion: High ILV = old low → fade dips in ranges.
  • Volatility timing: ILV on ATR nearing N → compression, prep expansion.

Mirror of IHV – 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 ≤ 5 – recent low confirms pressure.
  • Volatility squeeze: ILV on ATR high → low vol, breakout looming.

Strengths and Limitations

The Wins

  • Instant age of low – zero lag freshness check.
  • Versatile on any series.
  • Great for exits and filtering stale downside.
  • Simple timing enhancer.

The Gotchas

  • Flips on spike lows – filter needed.
  • Descriptive – pair with rules for action.
  • Oscillates in tight ranges.
  • No magnitude – 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.
