Migrate OHLC Data to Postgress

[zahin-mohammad]

For the purpose of this project, we don't actually need all the pricing data all the time. If the goal is to use the data for training a model, then we can store the data, train, and then flush the data on a set schedule. It should be enough to store the past 60 days worth of data, a big enough overlap of the last training time.

Pros:

• don't need two data stores
• simplifies code as we already use postgress Cons:
• lose out on the cool influx dashboard
• can't create a pricing server (not really a goal ATM)

We'd lose the ability to backtest without historical data.
