I need a function that returns the maximum lot size that can be traded (long) on an index without exceeding a % maximum draw down of the account and based on a % drop in the index value.

This is a repeat of my prior posting. (second developer)

I am posting this advert again so I can check the work against 2 separate developers.

I will use the most correct one in production.

Please refer to the attached word document for Use Case and Technical Requirements.

After you have checked the document, if you believe you can write this function and test it as per my requirement, then let me know.

I also want all testing to be backed up with calculations in excel so I can see your maths. This function needs to be absolutely correct and must be backed up with demonstratable testing and maths in excel

Thankyou

Jason
