Rate of Change Ratio (100 Scale) (ROCR100)

ROCR100 calculates the ratio of current price to price n periods ago, multiplied by 100, producing a centered oscillator around 100. The formula is (Current Price / Price n periods ago) × 100. When ROCR100 = 100, there's no change; above 100 indicates upward momentum; below 100 indicates downward momentum. With a default 10-period lookback, ROCR100 provides percentage-scaled momentum measurement. A value of 105 means price is 5% above the price 10 bars ago, while 95 means 5% below.

Cryptocurrency traders use ROCR100 as a momentum oscillator centered around 100 rather than zero, making it intuitive for percentage-based thinking. Values significantly above 100 (e.g., 110+) suggest strong upward momentum and potential overbought conditions; values significantly below 100 (e.g., 90-) suggest strong downward momentum. ROCR100 is particularly useful for comparing momentum across different crypto assets on a normalized scale. Combined with moving averages of ROCR100 itself to smooth signals, or with RSI for confirmation, it provides clear momentum assessment. Popular among traders preferring percentage-based indicators.
