alpha-trade

Overview

alpha-trade is a npm package with a purpose of simplifying all financial RESTful APIs. Currently, only the Polygon.IO API is supported. Find out more about Polygon.IO here: https://polygon.io/.

Features

Installation

Install the package using npm:

npm install alpha-trade

Usage

Note: In your .env file, you must declare POLYGON_API_KEY=your_api_key_here

// .env file
POLYGON_API_KEY=asdf1234asdf1234

By setting your Polygon API key in your .env file, alpha-trade can automatically grab your API key from your .env file.

We do not store or save your API key. Examine the package to verify this. Your API key is local only to your project and not to the alpha-trade package.

FetchAggregates(ticker, multiplier, timespan, from, to, adjusted, sort, limit)

Output will be an array of objects of the form:

 {
    v: 8,
    vw: 6.605,
    o: 6.62,
    c: 6.6,
    h: 6.62,
    l: 6.6,
    t: 1713326400000,
    n: 4
  }

Example usage:

const a = require("alpha-trade");

const main = async () => {
