Integrates the Real life stock market into Ren! Thought adding new ways to gain/lose credits might be fun. Also, has the added benefit of teaching people how to invest and gaining experience losing money. Unlike Squid.py, effort was put in. Oh, and comments... yea kinda forgot about those midway so, you got this! Its fairly simple code so should be alright without it. Couple of issues are still present in no particular order: - Its slow, that needs to be worked on, especially for the buy and sell functions - The output could be prettier. - Buy & Sell functions are kinda messy. Needs to be cleaned up. - For the charts, the time stamps are weird if you view a stock when its currently being traded on the market WIP/To-Do: - Dividends (think of it as adult allowance for the financial illiterate) - buy/sell with the full company name instead of tickers

Can you please make these paths platform-agnostic? This would work on Windows but not Linux.

Please include a info.json and put this as a requirements. You can see other cogs (i.e. YOURLS) for examples.

This should be protected by some mod/admin equivalent check.

Does this work if the filename doesn't match the one you're setting with set_image?

Probably some other places are using import *, but can we please explicitly import all attributes that you need? Makes tracing where names are coming from easier.

Any reason not to include default of 0 and let the infra print out the help string if the amount to sell isn't provided?

Re:user_id, can we rename this to something that doesn't include ID, since this is not a user ID but rather the Member object itself.

nit: does this need to be inside the class? I don't see self being used anywhere in this helper.
Messed up my local git repo so it doesn't contain the 30 or so changes. Still kinda figuring this stuff out.
