I'm currently using the "Progressive Win Odds " at the HKJC page. It's fine as far as it goes, but there's a delay between odds at the track and its posting on the website. I've also tried three different odds feeds in North America, and each of them is at least a minute behind real-time, meaning that by the time any significant late moves have come in, the race is off.

Is there a live (real-time) odds feed anywhere, even if it's subscription based?

Thanks in advance.
