Fix .exe Bitmex api problem

Job ID: 32597303

Budget: $250 – $750 USD

I have a .exe made in Visual Basic
It stopped working because bitmex changed their API.

Before I could open orders with lot of 1$ now the minimum is 100$.
Also, they changed bulk orders, which my bot needs to work:

I need someone to fix these two things.

My Budget total is up to $300
