Glossary
Trading has its own language. The PnL App Glossary defines the terms, indicators, and market structure concepts you will run into across every other section of this publication, written in plain terms rather than textbook jargon.

Discipline
What Is Trading Discipline?
Trading discipline is following your own rules on the trades where it is hardest to, not just on the easy ones. It is a behavior you can measure, not just a personality trait.

Risk Management
What Is Drawdown?
Drawdown measures the decline from a portfolio's peak value to its lowest point before a new peak is reached, and it is one of the clearest ways to judge risk.

Decision Making
What Is Analysis Paralysis?
Analysis paralysis is overanalyzing a trade to the point of missing the entry entirely. More indicators and more confirmation do not always mean a better decision.

Behavioral Finance
What Is Confirmation Bias in Trading?
Confirmation bias is the tendency to notice information that supports a trade you already want to take, while discounting signals that argue against it.

Behavioral Finance
What Is Loss Aversion?
Loss aversion is the tendency to feel a loss more intensely than an equivalent gain. In trading, it is a major reason traders hold losers too long and cut winners too early.

Discipline
What Is Revenge Trading?
Revenge trading is entering a new trade to win back a loss, rather than because a real setup appeared. It is one of the most common ways a small loss becomes a large one.

Emotional Trading
What Is FOMO in Trading?
FOMO is the fear of missing out on a move that is already underway. It pushes traders into chasing price instead of waiting for their own setup.

Discipline
What Is Trading Tilt?
Tilt is the state of trading from frustration or ego instead of a plan, usually right after a loss. Here is how to recognize it before it costs you more.
