DRAFT: WILL BE UPDATED SOON

• load simplified
• changed command chart to candle to match stocks

Trying out load BTC and not working for me:

I'd suggest having load bitcoin enabled too. A lot of people will use this like this

Nice work! 🚀 This is a much-needed one.

Some comments:

1. We should remove the auto-completion with source

2. When some symbols do not exist, this errors throws :(

3. Super small but my OCD cannot ignore this. Could we capitalize the Symbol?

Tested the dd commands with breaking changes and worked wonderfully!

Nice :) will go through your comments today

@jose-donato Let me know when it's ready and I'll review it. Let's get this bad boy out!

Now the load is not working at all..

When I loaded ADA in upper case, it said coin is not found. But in lower case that'd work. And circulating supply shouldn't be 0.

Same with AVAX

When the starting date is specified, an error was thrown

thanks for the help @Chavithra

When I use the load multiple times, coingecko would limit # of API calls. We should have an error message telling them that they should try again in a bit. Other than that, work perfectly! ✨
