Prices and fills

Is this a replay of an old session?

No. The tape is live and runs on a short delay.

Nothing here is a recording. A stored session exists only as a test fixture for the rule engine, never as something you trade against.

You cannot rewind, scrub or restart the tape, for the same reason a real evaluation does not let you. Knowing what happens next is the one thing that would make the whole exercise worthless.
