Financial Instrument Tracker Bug #39

Closed olivernjeru closed 2 months ago

olivernjeru commented 2 months ago

Precursor, I set the Financial Instrument Tracker API call to PolygonIO to be one day before and tested it out, it worked. However, when I set up the application and tried to load Financial Instrument Tracker values for the three stock tickers, AAPL, TSLA and AMZN, I did not get any value back. I ony got an error, too many requests aparently which did not yield back any values to populate the table. This made me reverse the values back to 3 days and perform thorough testing. After all tests passed, I then used three days to be the default value.

This did not sit well with me as even for a project like this, data from three days ago is not usable, it beats the whole point of this application, faciliating the connection between a client and a market maker. For this relationship to exist and even thrive, we have to have somewhat realtime data, well, we work with what we have at the very least.

This commit makes the PolygonIO API fetch only fetch one day before data for the Financial Instrument Tracker component, change startDate to be a day before. I have tested this out before pushing it, it works. I will keep an eye on it in the future just to make sure everything is okay and up to par in terms of performance and functionality.
