Dart TradingView Technical Analysis

An unofficial TradingView technical analysis client for Dart and Flutter. Get the same indicators, buy/sell recommendations and pivot levels you see on TradingView's technicals page, for many symbols and intervals at once.

A Dart take on the Python tradingview-ta library.

Features

Many symbols in one request (crypto, stocks, forex: anything TradingView's screeners cover).
91 indicators per symbol: oscillators, moving averages, Recommend.All / Recommend.MA / Recommend.Other, pivot points and more.
Several intervals in one request, from 1 minute to 1 month.
Support and resistance levels (S3 to R3), averaged over the Classic, Fibonacci, Camarilla and Woodie monthly pivots.
Built-in TradingView indicators only (Pine Script / custom indicators aren't available through this API).

Installation

dart pub add tradingview_ta

or, in a Flutter project:

flutter pub add tradingview_ta

Usage

import 'package:tradingview_ta/tradingview_ta.dart';

Future<void> main() async {
  final tradingViewTA = TradingViewTA(
    tradingView: TradingViewModel(
      screener: "crypto",
      symbols: ["BINANCE:BTCUSDT", "BINANCE:ETHUSDT"],
      interval: Intervals.INTERVAL_1_HOUR,
    ),
  );

  // Every indicator for each symbol at one interval
  List<Map<String, dynamic>> analysis = await tradingViewTA.getAnalysis();

  // The same symbols at several intervals, in one request
  List<Map<String, dynamic>> multiFrame =
      await tradingViewTA.getAnalysisWithMultiFrame(
    intervals: [Intervals.INTERVAL_1_DAY, Intervals.INTERVAL_1_WEEK],
  );

  // Support and resistance levels
  List<Map<String, dynamic>> levels =
      await tradingViewTA.getSupportAndResistant();

  print(analysis);
  print(multiFrame);
  print(levels);
}

A runnable version is in example/tradingview_ta_example.dart.

Results

getAnalysis(): one map per symbol.

{ticker: BINANCE:BTCUSDT, interval: 1h, indicators: [{indicatorsName: Recommend.All, value: -0.08}, {indicatorsName: RSI, value: 46.0}, ...]}

getAnalysisWithMultiFrame(): one map per symbol, one entry per interval.

{ticker: BINANCE:BTCUSDT, indicators: [{interval: 1d, indicators: [...]}, {interval: 1W, indicators: [...]}]}

getSupportAndResistant(): one map per symbol.

{ticker: BINANCE:BTCUSDT, SupportAndResistant: {r3: 87566.4, r2: 85003.3, r1: 82722.0, s1: 78538.8, s2: 77051.4, s3: 74011.9, middle: 81344.9}}

An indicator TradingView has no value for comes back as null. Recommend.* values run from -1 (strong sell) to 1 (strong buy).

API

Member	What it does
`TradingViewModel(screener:, symbols:, interval:)`	What to request. `screener` is e.g. `crypto`, `forex`, `america`; each symbol needs its exchange (`BINANCE:BTCUSDT`, `NASDAQ:AAPL`). `interval` defaults to 1 hour.
`TradingViewTA.getAnalysis()`	All indicators for each symbol at `interval`.
`TradingViewTA.getAnalysisWithMultiFrame(intervals:)`	All indicators for each symbol at each interval.
`TradingViewTA.getSupportAndResistant()`	S3–R3 and middle pivot levels for each symbol.
`Intervals`	`INTERVAL_1_MINUTE`, `INTERVAL_5_MINUTES`, `INTERVAL_15_MINUTES`, `INTERVAL_30_MINUTES`, `INTERVAL_1_HOUR`, `INTERVAL_2_HOURS`, `INTERVAL_4_HOURS`, `INTERVAL_1_DAY`, `INTERVAL_1_WEEK`, `INTERVAL_1_MONTH`

A symbol without an exchange, an empty screener, an empty intervals list or an error answer from TradingView throws an Exception.

Finding the symbol and screener: search the symbol on tradingview.com. The exchange prefix is shown next to the name (for example BINANCE:BTCUSDT), and the screener is the market: crypto, forex, cfd, or the country for stocks (america, uk, egypt, …).
