Trading Psychology: Decisions Under Risk

Trading psychology taught from the research on decisions under risk: why traders hold losers and cut winners, how overconfidence grows after a good run, what tilt and revenge trading look like, and the routines that protect you from yourself.

Trading psychology is usually taught as motivation. This course teaches it as evidence. Decades of research on decisions under risk explain why traders cut winners early, hold losers too long, size up after a lucky week and trade to win back a bad morning. Knowing the research does not make you immune, but it lets you build routines that catch the mistake before it costs money.

Why do traders hold losing trades too long?

Because a realised loss hurts more than an open one, and selling makes it real. Researchers call it the disposition effect and have found it in millions of brokerage accounts. The course shows you how to measure it in your own record and the rules that counter it.

How do you stop revenge trading?

Not with willpower. With rules written in advance that end the session after a set loss or a set number of losing trades, and a routine that makes you step away. The course has you design these rules and test them on your simulated trading.

Who is this course for?

Every trader on the trader path, and experienced traders whose results depend on their mood. No programming is needed.

What you will be able to do

  • Describe the main biases in trading decisions and the research behind each.
  • Identify your own patterns of tilt, revenge trading and overtrading from your record.
  • Design a pre-trade and post-trade routine that interrupts the costly ones.
  • Recognise the signs that trading has become a gambling problem, and what to do about it.

Questions applicants ask

Is trading psychology more important than strategy?

They are not alternatives. A method with no edge cannot be saved by discipline, and a method with an edge can be ruined without it. The course treats psychology as the part of execution that happens in your head.

Does the course include coaching sessions?

No. It is taught through readings, films and exercises, and your work receives written feedback from the faculty.
