Evening clearing session
The trading break in which the exchange settles the day on the derivatives market.
How to read the number
This is where a position's result becomes money: before clearing the profit on screen is an estimate, after it a balance.
When the metric lies
Orders are not executed during the break while collateral requirements may rise. A position that suited the account before clearing turns out to be underfunded after it, with nothing to be done meanwhile.
