Start with the position

Isolate the layer

Immediate checks

Frozen, slow or partial

A closed market is not a failure

A slow probe is not a dead feed

The loading veil is not a freeze

A late feed is not a lost feed

A drop does not always leave a visible hole

A hole in the middle of the session

Common causes

What cannot be repaired

Preparing a useful diagnosis

When not to trade
