Backtesting program for crypto exchanges (BitMEX, and Binance )

Hello 

I need a customized solution for the right programmer for the right price.

My project will include 3 things:

A backtesting program which can:

1. Pull historical data via api from Binance and BitMEX executed by update button

2. Must automatically and systematically run through a series of values to find the most optimal value to run my script

3. Conversion of my existing pine script to work in the program

I prefer the program be written in Go , Julia or Rust as they are great in terms of performance and features but not a requirement
