How do I pull OHLC data for a cryptocurrency?
As a cryptocurrency and finance practitioner, I often need to analyze market data for decision-making. One crucial piece of data is OHLC (Open, High, Low, Close) values for a specific cryptocurrency. Could you elaborate on the steps involved in retrieving this information? Specifically, I'm interested in knowing what sources or APIs I can utilize to access these data points, as well as any recommended practices or tools for analyzing the retrieved OHLC data. Additionally, are there any common challenges or limitations that I should be aware of while retrieving and working with OHLC data for cryptocurrencies?
