I know that a swap (more specific an IRS) is an OTC product to exchange future payments base on a principal. In this case, the interest on the fixed leg will be computed trying to have a NPV of 0, so far so good.
Now, I have seen that there is another type of IRS that seems to be traded on regulated financial markets, for example the Euro 10 yr Swap that have EUSA10 as Bloomberg tickers.
I have seen that this ¿Instrument? have "no maturity" as it's price is traded since late 90' as seen here: https://markets.ft.com/data/indices/tearsheet/summary?s=A@?EURIRSXY:RCT
What is the Euro 10 yr Swap product?
Are there future cash flows with this product? (like the OTC swaps that I know)
What does the price of the Euro 10 yr Swap indicates?
Thank you in advance,
