Go to OTC in the top menu or the footer. Or just open okcoin.com/otcdesk. Then check the table at the bottom of the page. The Recent quotes section shows all your quotes for the past 24 hours, available and expired. If you get a new quote before the previous one expires, you can click Buy or Sell to trade under the previous quote. You can also click Quote to get a new quote for the same trade if the previous quote expired. The Trade history section shows all your completed trades.
