Ensure that you zoom/pan such that the oldest date you desire is visible on TradingView before publishing the chart. Too many indicators or too low a time resolution will increase the data points and potentially overload the free server. Avoid this by hosting/running the script on your local machine or scraping multiple times with fewer indicators and manually combine the CSV afterwards.
Simply append the URL of a chart/idea published on TradingView to the link below. This is not the URL of a security's chart, but the URL for a user-published chart: https://tradingview-data.herokuapp.com/quotes?url=
i.e. for this chart: https://www.tradingview.com/chart/SPY/vjYfwgMu-SPY-Export-Test/
