I've now looked into API and am curious why this isn't being implemented?...
returnTradeHistory - Returns the past 200 trades for a given market, or up to 50,000 trades between a range specified in UNIX timestamps by the "start" and "end" GET parameters.

I've also familiarized myself now with restrictions of 6 API calls per second by IP.. Coinigy employs multiple IP addresses so if your API subkeys were rolling through while simultaneously rolling through their IP's, this would explain how this is helping eliminate this issue with their users.
Coinigy's current (subject to change at any time) list... 104.197.144.74, 104.154.21.31, 104.198.237.125, 104.197.40.47, 146.148.40.57, 104.154.38.52, 104.197.15.96, 104.198.238.180
This also means there is probably merit to the proxy service the member was recently posting on here. By merit I mean to the proxy idea. I don't have any opinion as far as their service. If they want to charge and users want to pay, power to them. Obviously I would rather come up with free method.
