Just came across this site yesterday. So how do the options usually work? Right now I see options listed on the site. Who is selling them ? Is it other traders or is the site selling those options ?
Normally other traders, although currently I think they are quoted by "the site". Doesn't really matter for you. If you want, you can place an order in the orderbook. Or you can trade with an order that's currently in the orderbook.
The reason I asked is because it allowed me to buy infinitely many options, which other traders usually don't do. And since it is a new site, I was wondering how is that possible.
