14. v0.8.9 — Pine strategy fidelity: request.security & overlay plots

Released 2026-07-11. Pine strategies and indicators now match TradingView more closely: request.security resolves from real market data on every timeframe, and a strategy's overlay plots (avg-entry / take-profit lines) render with the correct symbol, data, and line-break style. Follows v0.8.8.

Fixed

• Strategy backtests now feed request.security real data. The strategy backtester never wired the request.security data seam at all — cross-symbol and lower-timeframe requests silently resolved to na, and no mintick was passed. The backtester now discovers a strategy's security requests, fetches the required series, and injects them before the run.
• Same-symbol requests to a non-chart timeframe now fetch that timeframe. Previously a finer timeframe (e.g. a 4h RSI on a 1D chart) silently degraded to the chart series, and a higher timeframe (e.g. 4h on a 1H chart) was resampled from the chart's own bars — surfacing a just-closed higher-timeframe bar one chart-bar late. Both made strategies like an RSI-DCA diverge from TradingView. The host now fetches the real series for any non-chart same-symbol timeframe and injects it, and piner resolves it close-time aligned.
• Strategy overlay plots break at na gaps like TradingView. A Pine line plot with na gaps (e.g. a strategy's avg-entry line that's na between trades) rendered as long diagonals bridging the gaps, because lightweight-charts draws straight across whitespace. A new line primitive lifts the pen at each gap, drawing discrete segments exactly like TradingView's line-break style, while the host series keeps the price scale, crosshair value, and last-value label working. Plot line width is now honored too.
• Overlay plots on a futures symbol fetch the futures endpoint. The indicator-path security fetcher wasn't threaded the asset class, so a futures symbol resolved against the spot endpoint and came back empty. The asset class is now threaded through.
• A strategy's self request.security(syminfo.tickerid) sees the real symbol. The indicator compute context received an empty symbol, so a self-referential higher-timeframe request degraded to the chart timeframe instead of fetching its own HTF data. The chart symbol is now threaded into the context.

Changed

• Bumps piner to v0.8.0, which adds same-symbol injected-timeframe resolution (computeInjectedSameSymbol).
