Pine Script Compatibility
Implementation status of Pine Script v6 features in PyneCore
Pine Script Compatibility
PyneCore aims for high compatibility with TradingView’s Pine Script v6. This page tracks the implementation status of all major Pine Script features.
Note: PyneCore only supports Pine Script v6. Scripts written in v5 or earlier must be updated to v6 syntax (PyneComp handles this automatically during compilation).
Status Legend
| Symbol | Meaning |
|---|---|
| full | Fully implemented and tested against TradingView |
| partial | Partially implemented — see notes for limitations |
| stub | Function exists but returns na or raises NotImplementedError |
| stub/plugin | API accepted (scripts don’t break), but no real output — future plugin |
| plugin | Not in core — designed as future plugin extension point |
| — | Not applicable to offline execution |

Drawing Objects
Scripts using drawing objects will not error out — all API calls are accepted and object state is tracked in memory. However, PyneCore currently has no built-in visualization. A future plot plugin will consume the stored drawing data to render charts.
| Feature | Status | Notes |
|---|---|---|

box.* | stub/plugin | API functional, data stored — visualization via plugin |
table.* | stub/plugin | API functional, data stored — visualization via plugin |
polyline.* | stub/plugin | API functional, data stored — visualization via plugin |
linefill.* | stub/plugin | API functional, data stored — visualization via plugin |

| Feature | Reason |
|---|---|
varip | Intrabar persistence — offline bars are confirmed |
| Realtime bar updates | All bars are historical in offline mode |
alert() triggers | No broker/notification integration |
| Chart rendering | No visual chart — output is CSV |
input() UI widgets | Inputs are function parameters or TOML config |
| Order execution | Strategy simulator, not live trading |
Precision
PyneCore is precision-tested against TradingView:
- Indicator values: 0.001% relative tolerance, 0.00000001 absolute tolerance
- Strategy trades: Exact trade-by-trade matching (245+ trades verified)
- OHLCV data: float32 storage with 6-significant-digit rounding
