if that's the case I guess you kinda have close to zero chance finding the parlay that you actually want to bet , haven't seen them before and as you said there are none now so still have no idea regarding that
Yeah, it's basically probably the same few people making the parlays, they're fixed, usually ML bets on big games, so you have to take their picks at the odds they offer. Also you can search "parlay" or "multi" depending on how the market creator named them!
Alternatively, you make your own preferred parlay and offer it at odds better than you can find on Pinnacle... and then hope someone takes it or goes against it.
Create market: https://fairlay.com/market/new/ I actually don't really know the settings well enough to risk my btc haha but I think there are a few good guidelines. And then you advertise your parlay in the trollbox like some do, this one was today: https://fairlay.com/market/nfl-saturday-11-jan-2020-parlays/?referral=848f9827-9f32-42a7-9d56-51292aabbce3
