Can it be that it's a prediction market asset?

[startailcoon]

It's a prediction market, you can see it by the trading pair design. Ordinary markets have a / while a prediction market has a :.

Could be that we need to update this to make it possible to change the pair on PM as well.

@startailcoon @sschiessl-bcp I think we should do it, cause as for me, it was uncomfortable and confusing that after selecting this pair I could do anything and I need to manually remove pair from url and reload page to make market picker work again.

Anyone interested in this task ? If no one wants it, I could make it in 1 hour, but feel free to take it.

Feel free to work on it :)

My only question is, should we make the user aware that they are on a Prediction Market and not an ordinary market pair somehow?

[react-cat]

@startailcoon Maybe we could make some popup that will appear when user first time select prediction market. This way we can warn user that it is a prediction market, give a link where he can read more about prediction markets and it's differences from ordinary and of course a checkbox "never show again".
This could be a solution in case if you decide that we need to aware user.

And I have a question, what is that ?) Appears only on prediction market page

[sschiessl-bcp]

That is the "borrow & sell" button for prediction markets. I guess no one bothered to check it for new styling :)

As for the header, I agree that the header should be the same. Please check what extra special cases are in the header. As far as I remember its "only" that it allows only one market order (PREDICTION ASSET : ITS BACKING)
