What are the warning signs of problem trading?

Problem trading has a known signature: chasing losses, hiding the extent of losses, borrowing to trade, trading instead of sleeping, lying to family. The signs are listable, and listing them helps.

Post the signs you know:

• the behaviour that signals trouble
• how you check yourself against the list
• what to do if you recognise yourself

The scam guide covers external predators; this thread covers internal ones.
