TAAPI.IO
TAAPI.IO is an API that calculates Technical Analysis Indicator values.
This NPM package is a wrapper and a client for communicating with the TAAPI.IO API
Using this service requires registration. Please check TAAPI.IO. We offer free and paid plans.
Please refer to our main TAAPI.IO Documentation. Here we will provide in-depts explainations and examples.
Getting started
- Sign up for a free/paid API key at TAAPI.IO
- Create a new node project: npm init
- Install this package: npm i taapi --save
Usage
Get started quickly with NodeJS and calculate indicator values with very few lines of code.
- Create your entry js file (index.js / index.ts for instance) containing:
import Taapi from 'taapi';
const taapi = new Taapi("<MY_SECRET>");
taapi.getIndicator("rsi", "BTC/USDT", "1h").then( rsi => {
console.log(rsi.value);
});
Fetch the last closed 200 period Exponential Moving Average for Bitcoin to the Dollar on the 1 hour timeframe from the Bybit exchange.
import Taapi from 'taapi';
const taapi = new Taapi("<MY_SECRET>");
taapi.getIndicator("ema", "BTC/USDT", "1h", { period: 200, backtrack: 1 }, "bybit").then( ema => {
console.log(ema);
});
Stocks & Forex
Using our integration partner Polygon.io, you can easily fetch indicators from the US Stocks & Forex markets. Visit our guide on how to use Polygon.io with TAAPI.IO for detailed explanations.
import Taapi from 'taapi';
const taapi = new Taapi("<MY_SECRET>");
taapi.setProvider("polygon", "<POLYGON_SECRET>");
taapi.getIndicator("macd", "AAPL", "1d", {
type: "stocks"
}).then( macd => {
console.log(macd);
});
For Forex examples, please visit out main documentation.
Calling multiple indicators in Bulk
import Taapi from 'taapi';
const taapi = new Taapi("<MY_SECRET>");
taapi.resetBulkConstructs();
taapi.addCalculation("rsi", "BTC/USDT", "1h", "rsi_1h");
taapi.addCalculation("macd", "BTC/USDT", "1h", "macd_1h");
taapi.addCalculation("ema", "BTC/USDT", "1h", "ema_fast_1h", { period: 9, backtrack: 1 });
taapi.addCalculation("ema", "BTC/USDT", "1h", "ema_slow_1h", { period: 20, backtrack: 1 });
taapi.executeBulk().then( results => {
console.log(results);
}).catch( error => {
console.error(error)
});
v1.4.0 Breaking Updates
As of version 1.4.0 of this NPM package is completely rewritten in TypeScript. It does not use CCXT anymore as the data-source, but TAAPI.IO's inhouse data source. To keep using the legacy CCXT client, please see the: taapi-ccxt package. Alternatively install this package version 1.3.1
