Includes error handling and checks for no data. ```javascript getBars: async (symbolInfo, resolution, periodParams, onResult, onError) => { const { from, to, countBack, firstDataRequest } = periodParams; console.log('[getBars]: Fetching bars for', symbolInfo.name, resolution, 'from', from, 'to', to); try { const response = await fetch( `https://api.example.com/history?symbol=${symbolInfo.ticker}&resolution=${resolution}&from=${from}&to=${to}` ); const data = await response.json(); if (!data.bars || data.bars.length === 0) { onResult([], { noData: true }); return; } // Bars must be in ascending time order const bars = data.bars.map(bar => ({ time: bar.time * 1000, // Convert to milliseconds open: bar.open, high: bar.high, low: bar.low, close: bar.close, volume: bar.volume })).sort((a, b) => a.time - b.time); console.log('[getBars]: Loaded', bars.length, 'bars'); onResult(bars, { noData: false }); } catch (error) { console.error('[getBars]: Error', error); onError('Failed to fetch historical data'); } } ``` -------------------------------- ### Search TradingView Symbols Source: https://context7.com/1of1adam/tradingviewllmcontext/llms.txt Searches for trading symbols based on user input, exchange, and symbol type. It fetches data from a /search API endpoint and returns an array of symbol objects. Dependencies include the fetch API. ```javascript searchSymbols: async (userInput, exchange, symbolType, onResult) => { console.log('[searchSymbols]: Searching for', userInput); try { const response = await fetch( `https://api.example.com/search?query=${encodeURIComponent(userInput)}&exchange=${exchange}&type=${symbolType}` ); const data = await response.json(); const symbols = data.results.map(item => ({ symbol: item.symbol, full_name: item.full_name, description: item.description, exchange: item.exchange, ticker: item.ticker, type: item.type })); onResult(symbols); } catch (error) { console.error('[searchSymbols]: Error', error); onResult([]); } } ``` -------------------------------- ### Retrieve Account Information Data Source: https://context7.com/1of1adam/tradingviewllmcontext/llms.txt An asynchronous function to fetch account information data. It returns an array of objects, each representing a property and its corresponding value for the account. ```javascript async getAccountInfoData() { return [ { property: "Account ID", value: this.accountId }, { property: "Account Type", value: "Margin" }, { property: "Leverage", value: "1:100" }, { property: "Currency", value: "USD" } ]; } ``` -------------------------------- ### Implement Real-time Bar Unsubscriptions (JavaScript) Source: https://context7.com/1of1adam/tradingviewllmcontext/llms.txt Unsubscribes from real-time bar updates for a specific listener. It sends an 'unsubscribe' message via WebSocket and cleans up the local subscription data. If no active subscriptions remain, it closes the WebSocket connection. ```javascript unsubscribeBars: (listenerGuid) => { console.log('[unsubscribeBars]: Unsubscribing', listenerGuid); const subscription = subscriptions[listenerGuid]; if (subscription && ws && ws.readyState === WebSocket.OPEN) { ws.send(JSON.stringify({ action: 'unsubscribe', channel: subscription.channelString })); } delete subscriptions[listenerGuid]; // Close WebSocket if no active subscriptions if (Object.keys(subscriptions).length === 0 && ws) { ws.close(); ws = null; } } ``` -------------------------------- ### Create Technical Studies on Chart (JavaScript) Source: https://context7.com/1of1adam/tradingviewllmcontext/llms.txt Adds various technical indicators (Moving Average, RSI, Bollinger Bands) to a TradingView chart programmatically after it's ready. It allows for customization of indicator parameters and plot styles. It also demonstrates how to remove a study after a specified delay. ```javascript widget.onChartReady(() => { const chart = widget.activeChart(); // Add Moving Average with custom parameters const maStudyId = chart.createStudy('Moving Average', false, false, { length: 20 }, // Input parameters { 'Plot.color': '#2196F3', 'Plot.linewidth': 2, 'Plot.transparency': 0 } ); // Add RSI indicator in separate pane const rsiStudyId = chart.createStudy('Relative Strength Index', false, false, { length: 14 }, { 'plot.color': '#9C27B0', 'upper band.value': 70, 'lower band.value': 30 } ); // Add Bollinger Bands const bbStudyId = chart.createStudy('Bollinger Bands', false, false, { length: 20, stdDev: 2 }, { 'Plot.color': '#FF9800' } ); console.log('Studies created:', maStudyId, rsiStudyId, bbStudyId); // Remove a study later setTimeout(() => { chart.removeStudy(maStudyId); console.log('Moving Average removed'); }, 10000); }); ``` -------------------------------- ### Resolve TradingView Symbol Metadata Source: https://context7.com/1of1adam/tradingviewllmcontext/llms.txt Resolves a symbol name to retrieve its complete metadata and configuration required by TradingView. It fetches data from a /symbols API endpoint and returns a structured symbolInfo object. Handles potential errors during resolution. ```javascript resolveSymbol: async (symbolName, onResolve, onError, extension) => { console.log('[resolveSymbol]: Resolving', symbolName); try { const response = await fetch(`https://api.example.com/symbols/${symbolName}`); const data = await response.json(); const symbolInfo = { name: data.name, ticker: data.ticker || data.name, description: data.description, type: data.type, session: data.session || "24x7", timezone: data.timezone || "Etc/UTC", exchange: data.exchange, minmov: 1, pricescale: 100, has_intraday: true, has_weekly_and_monthly: true, supported_resolutions: ["1", "5", "15", "30", "60", "240", "1D", "1W", "1M"], volume_precision: 2, data_status: "streaming", format: "price", currency_code: data.currency || "USD" }; console.log('[resolveSymbol]: Symbol resolved:', symbolInfo); onResolve(symbolInfo); } catch (error) { console.error('[resolveSymbol]: Error', error); onError('Symbol not found'); } } ``` === COMPLETE CONTENT === This response contains all available snippets from this library.
