AutoTools JSON randomly sorting

I have the following JSON data through a url. I am using auto tools to put the symbol and lastPriceInDouble into its own arrays. however, when i output the array, the symbols are not in the same order they are displayed on JSON data. I'm not sure how its sorting, but right now its showing as /ZNH19 /CL /GC /ES /ZBH19. This order changes sometimes as well. The JSON header data has this sorted as /ES /ZBH19 /ZNH19 /GC /CL. How do i get it to sort in the order as displayed by the JSON data?
