Definitions
In plain terms
Some indicators remember their previous result. That remembered value is the recursive state used together with the newest input to calculate the next result.
Technical
Recursive state is the minimum persisted value or tuple required to evaluate a recurrence at t from current input and state at t-1 without recomputing the full prefix.
Scope
The concept describes implementation state, not an economic market state; serialization precision and recovery behavior are separate package choices.
Examples
- The prior 10% Trend and prior 5% Trend are the two recursive states needed for the next McClellan Oscillator update.
Common misconceptions
- Recursive state is not safely interchangeable with the last displayed rounded output.
