Which TA library are you using? If you are using the Pandas-TA (https://github.com/twopirllc/pandas-ta) which I HIGHLY recommend, then it uses a Pandas Dataframe by default. With a Pandas Dataframe you can easily drop rows of old data from your data every hour. And you can easily write the data to file so in the event your bot has a hiccup it can restore itself very very quickly. And the library works nicely with tick data.
