Jaspers TradingView Chart: Shows TradingView's advanced chart widget in a frame, driven by panel state (symbol, interval, studies), reporting back the last quote.
| 1 | // What the orchestrator is told while a chart element is focused: how to drive the widget by state, |
| 2 | // and what it cannot tell you, since TradingView draws it on a page the app cannot read. |

| 5 | "A TradingView chart: TradingView's own widget, drawn with TradingView's data. state.symbol is EXCHANGE:TICKER (NASDAQ:AAPL, NYSE:JPM, AMEX:SPY, BINANCE:BTCUSDT, FX:EURUSD, TVC:DXY); a bare US ticker works too.", |
| 6 | "An index, a future, a commodity, or a coin the user names in words also works, and is resolved to the symbol TradingView charts it under: S&P 500, SPX, or SP500 -> SP:SPX; NASDAQ 100 or NDX -> NASDAQ:NDX; Nasdaq Composite or IXIC -> NASDAQ:IXIC; Dow, DJIA, or DJI -> DJ:DJI; Russell 2000 or RUT -> TVC:RUT; VIX -> CBOE:VIX; DXY -> TVC:DXY; US 10Y -> TVC:US10Y; US 2Y -> TVC:US02Y; gold -> TVC:GOLD; silver -> TVC:SILVER; oil or WTI -> TVC:USOIL; ES or S&P futures -> CME_MINI:ES1!; NQ -> CME_MINI:NQ1!; bitcoin or BTC -> BINANCE:BTCUSDT; ethereum or ETH -> BINANCE:ETHUSDT. A symbol written with an exchange is never rewritten, so NYSE:GOLD is the miner and gold is the metal.", |
| 7 | 'state.interval is the bar size: 1, 3, 5, 15, 30, 60, 120, 180, or 240 minutes, D, W, or M. state.range is how much history shows: 1D, 5D, 1M, 3M, 6M, YTD, 12M, 60M, or ALL. With a range set the widget picks the bar size for it, so when the user names a bar size, set interval and set range to null.', |
| 8 | 'state.style is candles, bars, line, area, heikin-ashi, or hollow-candles. state.studies adds up to five indicators, which is all the widget takes: rsi, macd, sma, ema, bollinger-bands, vwap, stochastic, stochastic-rsi, atr, adx, obv, cci, keltner-channels, donchian-channels, parabolic-sar. Volume is already under the price, so there is no study for it.', |
| 9 | 'state.compare draws up to three other symbols over the main one in its pane, named the way state.symbol is (["SP:SPX"], ["gold", "oil"]); null clears them. Only the main symbol reports a price, so output.quote never covers a compared one. state.extendedHours true adds pre- and post-market bars where the exchange has them; null or false is regular hours.', |
| 10 | "To show another symbol or change how it is drawn, set the focused chart's state; place a second chart only when the user wants two at once.", |
| 11 | 'output.quote is the last price TradingView reported for the symbol on screen (name, exchange, last, change, changePercent, volume), refreshed at most every 15 seconds; read it when the user asks what the chart shows. The bars, the indicator values, and anything drawn on the chart cannot be read.', |
| 12 | 'The user can pick another symbol in the chart itself, and state does not hear about it: when output.quote.name is not the ticker in state.symbol, the chart is showing output.quote.name, so set symbol to it along with any other change, or the chart goes back to state.symbol.', |
