Download OHLC data

ohlc_download

Running this script will create a folder in the current directory called 'ohlc_csv' if there isn't one already by that name. It will then take you through a series of prompts:

Download data for one or multiple tickers

You can choose to get data for one ticker or multiple tickers at once. Tickers don't have to be typed in capital letters.

Choose source

You can then choose which API to use. Alpaca requires API keys that you'll be prompted to enter, yfinance does not require API keys.
