Indices of Minimum and Maximum (Time Since Range Extremes) (MINMAXINDEX)

MINMAXINDEX returns both the index of the minimum and maximum values over the lookback period (default 30) - showing how many bars ago each extreme occurred. Two outputs: bars since low and bars since high. This provides complete timing information about recent range extremes in one efficient call. Values of 0 indicate the current bar is at that extreme.

Traders use MINMAXINDEX to assess range dynamics and momentum. When both indices are low (recent extremes), the market is volatile and ranging. When both indices are high (old extremes), price is consolidating mid-range. Asymmetry reveals bias - if min index >> max index, price is near highs (bullish); reverse suggests bearish. Essential for range analysis and regime detection.
