If they negotiate as stated below on the website you are quoting it is NOT automated. lol
Here is directly from the OTC website you stated "Subscribing broker-dealers view and publish quotes and negotiate trades in OTCQX®, OTCQB® and Pink® securities on our SEC-registered Alternative Trading System, OTC Link® ATS, an interdealer quotation and trade messaging system. Broker-dealers access OTC Link® ATS through our OTC Dealer®, user interface or by using OTC FIX protocol."
