Here is a example of delusions , apply same delusions to a trader
At five foot six and 270 pounds, the bank robber was impossible to miss. On April 19, 1995, he hit two Pittsburgh banks in broad daylight. Security cameras picked up good images of his face — he wore no mask — and showed him holding a gun to the teller. Police made sure the footage was broadcast on the local eleven o’clock news. A tip came in within minutes, and just after midnight, the police were knocking on the suspect’s door in McKeesport. Identified as McArthur Wheeler, he was incredulous. “But I wore the juice,” he said.
Wheeler told police he rubbed lemon juice on his face to make it invisible to security cameras. Detectives concluded he was not delusional, not on drugs — just incredibly mistaken.
