History

Source

Every stored reading from this source, whenever it was taken

A reconstruction is written where a replay ran rather than on the scan's cadence, so there is no window to choose: the engine returns the readings it holds and the axis below is labelled from them.

No readings were stored in this range from this source

The engine holds no stored reading for Offers implied on this asset. A reconstruction exists only where keel replay has been run, and it has been run on one pair.

Checks

What fires now, how long it has been firing across the window above, and what could not run.
