Central bank holds rates at the next meeting?
How it resolves
It settles Yes if the central bank leaves its policy rate where it is at the next scheduled meeting, and No if they move it in either direction.
What we'd look at
Central banks rarely like to surprise anyone, so most of the work is reading what they've already said. If the last few speeches have all leaned the same way we'd be wary of paying much over 90¢ for a hold, because the cheap side is where the surprises live.
About practice markets
The price here is simulated, which means nobody's on the other side and nothing you do will move it. We built it that way on purpose, because the habit we want you to pick up is checking a price against your own number before you trade, and that's far easier to practise when a mistake costs you nothing. Try putting in a probability that's a few points away from the price and watch what happens to the expected value and the Kelly stake (that's the whole course in miniature).
