Description

Add missing support for inverse

I'm currently investigating if there are changes required in the brokerage model due to a slightly different order handling. But this should only affect backtests.

How/where is this going to be used?

It's not used but the question is if it should. Hedge mode is currently not supported and for inverse the default mode is hege which can only be changed to normal mode by using the API.
So should this be done automatically or is the user responsible for that, if so is there a way to make this function available to the user in any way. It would definitely need to be documented.

Another comment, trading inverse contracts with the Unified Trading Account will use the Inverse Derivatives account, so balance and margin will be used from the Inverse Derivatives account.

  • Perhaps we need to modify which account we want to fetch the initial balance from? https://bybit-exchange.github.io/docs/v5/account/wallet-balance
    • "Account type: Unified account: UNIFIED (trade spot/linear/options), CONTRACT(trade inverse)"
  • How will the we know which account to used?
    • Do we need a different brokerage class for this case for inverse contracts trading only?
    • If so, would we need a new brokerage factory as well?

Will double check the different wallet-balance endpoints.

Yes it seems that's the case. Will add a new brokerage factory and adjust the Brokerage again so it can be inherited from.
