Hi,
I have over 8 yrs of experience working on excel and scripting languages like python and php.
I understand that you need the variation in stock prices. How do you want the price range to be calculated - between two days, over he period in the txt file, or intraday.
I dont want any upfront payment, milestone number is only due to freelancer requirement and is optional for you.
Let me know when we can start the work.
thanks & regards
