Thanks for the quick reply. I've just noticed that it the price gets listed regularly on steemd for witnesses so I'm figuring it's on the BC so I'm going to see if there's a way to query for it with curl. I presume there's a call for the current price feed but not sure how to get to previous entries.

Thank you for the kind vote @timcliff.
I have decided to use to javascript to parse the info from steemd instead as that will be quicker given my little knowledge of querying the steem bc.
