We've removed the calendar from the site for now. (it was in beta)

Sometimes they say something is high impact when it isn't. Today is a good example. I've had two people tell me that "TIC Net Long-Term Transactions" is irrelevant and yet it's got a red mark by it.
High impact only applies if the actual result is way off to the forecast. In most cases the market moves quite a way on pretty much all high impact labelled items. That said you will get situations when a large discrepancy has no impact on the market move and other times when no discrepancy results is a large market move. The issue being that ultimately markets are not predictable
