Is there any place where I can find the number of orders that were executed by buying or selling? I wonder if at one point people are looking for the order that is in the purchase book or that is in the sales book.
You can see all orders that were executed by buying or selling on any decentralized exchange. The list of the links to every trading transaction is shown there. But that's concerned to Ethereum or other crypto-currency of such kind, not to Bitcoin.
