@jacks821 looks pretty good. Thanks for taking this on, I've been busy with some other projects. Can you look into the failing checks? Also, for full integration tests, I suppose we'll need a modification to the test server project https://github.com/piquette/finance-mock (annoying I know). Let me know if you have any thoughts. Maybe a unit test will suffice?

[jacks821]

I appreciate the feedback! I'm gonna do that and re up the commit!

[ackleymi]

@jacks821 maybe add some basic input verification like empty string check, int == 0 , etc.

[ackleymi]

@jacks821 and what is your thoughts on returning the day's OHLC values, instead of just the close?

[jacks821]

I like that idea a lot. But I think i'd have to build it a little differently, unless you have an idea of how to do that using the Chart API? I'll work on just doing it separately.

[ackleymi]

I'll work up an example and post it here in a bit

[jacks821]

I fixed it so that it returns the OHLC values as just a ChartBar. I just wasn't understanding how the Iters worked.

@jacks821 this looks ok to merge. I'll tack on a follow up PR that adds gofmt shortcuts to the Makefile and make sure its listed in the requirements for subsequent PRs. I'll ping you that PR when I'm done to show you what I mean. :)

[jacks821]

I don't mean to push you, just wanted to see if you were gonna show me those shortcuts? Also, i noticed you're from Ann Arbor. I'm originally from Detroit, myself.

@jacks821 whoops got sidetracked with another project, I merged it.
