Okay so this is my stock market app basically and what I want to do is to check the prices of certain stocks when the market opens and closes. In order for me to check this through I would need to run this code over a certain period of time. I tried to use time.time() and another variable future which is 10 seconds after the current time. The while loop is to check the stock prices over that time but for some reason, the while loop is infinite and doesn't exit the loop ever. How can I make it so that I check the price of each stock perhaps every hour or so?

You can call:

https://financialmodelingprep.com/api/v3/is-the-market-open

and look for the property: isTheStockMarketOpen

if isTheStockMarketOpen is true -> the market is open
