Code from MT4 to calgo

i got an mt4 indicator calculates me the average daily range - http://mq4tocalgo.apphb.com/ tells me its 16 mistakes within the code i would need someone fix that for me and turn it into a functioning indicator for ctrader platfom

total length of the code is 450ish lines, should be a easy job to do as i got told 

30-50 usd is budget - payment channel would be paypal i guess - no need to use any platforms cut something from the price
