Pulling candlestick data one ticker at a time doesn’t scale. Whether you’re building a backtesting pipeline, training a price-prediction model, or simply archiving market history, you need to download OHLCV data for dozens or hundreds of instruments in a single run reliably, without hitting rate limits, and ideally across more than one market.<\/p>\n\n\n\n
This guide shows how to do that using Infoway API<\/a>, which covers equities, forex, futures, and crypto across multiple global exchanges. All examples are in Python and ready to run.<\/p>\n\n\n\n One API key gives you candlestick data across the following markets:<\/p>\n\n\n\n All markets share the same endpoint structure and response format, so the same download script works everywhere, you only change the ticker symbols.<\/p>\n\n\n\n Minute-level history goes back 3 years<\/strong>. Daily and above have no lookback limit.<\/p>\n<\/blockquote>\n\n\n\n There are two ways to connect: the official Python SDK<\/a> (recommended) or direct HTTP requests. The SDK handles authentication, serialization, and error wrapping for you.<\/p>\n\n\n\n Python SDK:<\/strong><\/p>\n\n\n\nMarket Coverage<\/h2>\n\n\n\n
