Wallets available balance returns 0 value for all pairs on v2 API

[abronan]

The purpose of having available balances on v2 wallets endpoint is unclear. No response is returned as opposed to the v1 API which returns the value correctly.

Issue type

• [x] bug
• [ ] missing functionality
• [ ] performance
• [ ] feature request

Brief description

When hitting v2 wallets endpoint, the values for available is always null.

Example of response:

[["exchange","BTC",0.00100884,0,null,null,null],["exchange","IOS",598.8,0,null,null,null],["exchange","IOT",19.96,0,null,null,null],["exchange","OMG",6.8e-7,0,null,null,null],["margin","BTC",0.00877305,0,null,null,null]]

Expected

Value is equal to total or less depending on the available amount.

Steps to reproduce

• Simply hit the wallets endpoint on v2 API.

Additional Notes:

• This works well with v1 API but is broken with v2. This makes it difficult to migrate from v1 to v2 if the client expects a value populated for the available balance.
