Message in the PR request to understand the context of the change
In the course of reviewing this PR we found two issues.
1. there are multiple places where the get_instruments() method is used,
and we feel that scripts.index.py is the best place for the
get_instruments() method to go.
2. data_collector.utils has some very generic stuff put inside it.
* refactor: improve brazils stocks download speed
The reason to use retry=2 is due to the fact that
Yahoo Finance unfortunately does not keep track of the majority
of Brazilian stocks.
Therefore, the decorator deco_retry with retry argument
set to 5 will keep trying to get the stock data 5 times,
which makes the code to download Brazilians stocks very slow.
In future, this may change, but for now
I suggest to leave retry argument to 1 or 2 in
order to improve download speed.
In order to achieve this code logic an argument called retry_config
was added into YahooCollectorBR1d and YahooCollectorBR1min
* fix: added __main__ at the bottom of the script
* refactor: changed interface inside each index
Using partial as `fire.Fire(partial(get_instruments, market_index="br_index" ))`
will make the interface easier for the user to execute the script.
Then all the collector.py CLI in each folder can remove a redundant arguments.
* refactor: implemented class interface retry into YahooCollectorBR
* docs: added BR as a possible region into the documentation
* refactor: make retry attribute part of the interface
This way we don't have to use hasattr to access the retry attribute as previously done
* Skip idx.is_lexsorted() when pandas version is larger than 1.3.0. The future warning is annoying.
