[IMPROVE] Adjust ticker to default when selecting a different exchange

[JerBouma]

What's the feature that should be improved? When you select a different ticker that is listed on a different exchange, e.g. AAPL.BA. You are going to notice that a lot of things don't work. So if I load it in:

Describe how you would like the feature improved A couple of options (from simple to extensive):

1. Do not allow data from different exchanges.
2. When you load ticker into different exchange/currency than default, notify the user that a lot of commands rely on the main ticker (e.g. AAPL) and simply do not do anything with the fact that a lot of errors will be thrown.
3. Whenever you load a ticker that includes the exchange, load in only specific data and then revert back to the main symbol (AAPL.BA --> AAPL) for everything else. This needs to be properly communicated so that people understand that the numbers they look at may not be in the currency they are buying in (and USD instead).
4. Do the same as 1) but convert all numbers into the right currency.

Possibly describe the ideal way to improve this To me, the ideal way is the third option. Not modifying data while still giving people access to all of it.

One thing to remember here is that stock ticker is not guaranteed to be unique across different stock exchanges. For example, BBCA and BBCA.JK represent two completely different things. Tickers might be somewhat unique across the US exchages, but definitely not internationally.

I think Finviz lists only US exchanges, but if other data sources listing tickers internationally (Yahoo Finance for example) are used, I'd be very careful tinkering with the ticker.
