Support API of USDM futures

[siegfried]

Does this project accepts features of USDM? Shall I add them to binance.R or a new file?

[daroczig]

I am not familiar with the USDM features, but based on a quick search, I think it would be a great extension, so looking forward to any help 🙇

binance.R grew super large already (it was named that way as originally this package supported multiple crypto exchanges), so feel free to start a new file.

Thanks!

I think binance_query() is reusable. For most of the API on USDM we just need to point the host to https://fapi.binance.com. I can make the base here as an argument.
However, for functions like binance_new_order() need new counterparts since the orders on USDM are different. What do you propose the function names would be? Shall I rename the current spot specific functions and move them to a different file?

binancer/R/binance.R

Line 112 in 8cfdfe3

base = 'https://api.binance.com',

May I use tibble of dplyr instead of data.table in this project? @daroczig

[daroczig]

Sorry, I'd rather not mix dplyr and data.table in the same project.

On the other hand, if you are asking about the user-facing result, I've done this on a configurable way in another project of mine https://github.com/daroczig/dbr/blob/master/R/db.R#L131-L137

[siegfried]

It's fine. I don't want to mix them either.
