Real-time chart analysis needs deterministic updates per bar and explicit handling of warm-up periods. SOLAR addresses this by implementing Calculates precise solar cycle value using Sun's ecliptic longitude. with parameterized inputs and direct state progression.
This implementation favors streaming execution over batch recomputation. The trade-off is more attention to state initialization, but latency stays predictable when charts scale.
Calculates precise solar cycle value using Sun's ecliptic longitude.
| Parameter | Purpose |
|---|---|
barTime |
int The timestamp of the bar (open time) in milliseconds. |
- float Solar cycle value from -1.0 (winter solstice) through 0.0 (equinoxes) to +1.0 (summer solstice).
- Declared optimization: for performance and dirty data
- Streaming model: single-pass update on each new bar.
- Warm-up behavior: outputs can be unstable until enough samples satisfy
lookback parameter. - Memory model: state is kept in Pine series context rather than external buffers.
Streaming logic keeps incremental cost stable, but initialization and edge-case handling become first-class concerns. That is a deliberate choice: predictable execution beats opaque recalculation spikes in live charts.
- Open the script in TradingView and confirm it compiles under Pine Script v6.
- Validate warm-up behavior on sparse data and short histories.
- Compare output against a trusted reference implementation for the same parameters.
- Confirm parameter bounds reject invalid values without silent fallback.
