Oonln Advanced Charts

TradingView Charting Library

Demo | Documentation | Tutorial | Discord community

This repository contains the TradingView Advanced Charts package. If you use Git in your project, please feel free to use this repository as a submodule in yours.

The master branch contains the most recent features and fixes.

Before using the library, please read the documentation and the Best Practices article.

Polygon datafeeds

Rather than using TradingView datafeed or sample datafeeds, the script uses datafeeds from Polygon in order to incorporate our own CSV file, which contains user's transactions of different type, like stock, option. Please read the Stocks API documentation, which provides REST endpoints that let you query the latest market data from all US stock exchanges.

NOTE: since we're using free-tier serivce, we have 5 API calls per minute.
