Recently, I retrieved order book data for 674 trading pairs. Each pair has been monitored for 11 days, and the data consists of the best bid and ask price within each minute (with some minutes missing).
674 trading pairs is huge but how many exchange on which you retrieved those data?
What are best best bid and ask price within 1 minute? With one minute, thing can only be done by trading bot if you discover any tutorial to get profit from your data processing. Normal traders will not be able to use it and get profit.
