Constructing an adaptive stochastic RSI

A stochastic RSI rescales a 14-period RSI inside its own recent high-low range. When lowest-value and highest-value functions cannot accept a variable period, the adaptive form selects among lookbacks 8 through 12 with a period clamp on a volume-conditioned adjustment.

  • A stochastic RSI applies a range rescale to a 14-period RSI series, mapping the current reading onto the interval between the lowest and highest RSI over a lookback.
  • If lowest-value and highest-value functions cannot take a variable period, compute independent stochastic RSI branches at lookbacks 8, 9, 10, 11, and 12, then select one.
  • The volume-conditioned adjustment is the rounded 60-interval volume term minus the rounded 60-interval oscillator term plus 11, then a period clamp keeps the chosen lookback between 8 and 12.
  • The discrete-branch pattern can be reused for other dynamic formulas if nested conditionals are split rather than stacked too deeply.

Range rescale of RSI

A stochastic RSI is a composite oscillator that applies a stochastic high-low rescale to an RSI series rather than to raw price. The range rescale maps that series onto the interval between its lowest and highest values over a lookback.

The base construction uses a 14-period RSI as the series being rescaled. The mapped value is formed by subtracting the lowest RSI over the lookback from the current RSI and dividing by the difference between the highest and lowest RSI over that same lookback.

Fixed-period branches

When lowest-value and highest-value functions cannot accept a variable period, the adaptive form is built by computing separate fixed-period branches and selecting among them.

Stochastic RSI is recomputed independently at lookbacks 8, 9, 10, 11, and 12. The composite output is the branch whose lookback matches the limited adjustment.

Volume-conditioned adjustment

Oscillator variability enters the adjustment as the 60-interval standard deviation of stochastic RSI, divided by 0.053 and then rounded. Volume variability enters as the rounded 60-interval standard deviation of a 14-period smoothed volume series after that series is divided by 1,000,000.

The raw adjustment equals the rounded volume term minus the rounded oscillator term plus 11. A period clamp then limits the score so the chosen lookback cannot fall below 8 or rise above 12.

Splitting nested conditionals

The same discrete-branch pattern is described as reusable for other dynamic formulas if nested conditionals are split rather than stacked too deeply.
