Historical Data Scanning/Screening for Crypto Pairs?

Hey guys, im looking to investigate trading in crypto markets. I have plenty of familiarity with the general markets as someone who has been a crypto user for many years, however ive ran into a bit of a dilemma.

I want to deploy a strategy alongside a scanner/screener that will alert for me whenever certain volume, price, and market cap criteria are met. This sort of opportunistic approach to trading cryptocurrencies seems to be common, but how do you go about backtesting such a system if I dont know when my scanner alerted in the past?

Im looking for a scanner that offers DATE as an input parameter, so I can look at what my scanner would have outputted on a prior historical date. This sort of tool is surprisingly hard to come by. Even in stock trading I had to search quite hard to find this sort of tool, especially for a reasonable price. I already have historical charts, I just need to know what my scanner would have alerted.

The closest thing ive found so far that is helpful is this CMC link that provides basic price, market cap, and volume info on some historical dates. Purchasing/acquiring .csv time and sales data might be an option, however it will be difficult to work with (id have to sort through (and purchase) data for every single crypto pair), and is the worst case scenario. For comparison, I use ChartMill right now for stock trading (its truly an incredibly powerful tool, I highly recommend it for stock traders), im looking for something EXACTLY like this, except for coins. My last resort is to compile the data myself by just documenting my scanner alerts for the next few months...

Any advice is helpful, thanks.
