Definition

A professional trading system is a complete framework that defines:

• What markets to trade.

• When to enter.

• When to exit.

• How much risk to take.

• How performance is measured.

• How decisions are improved.

A trading system is not:

"Buy when RSI is low."

A complete system answers:

What conditions create an advantage, how is that advantage measured, and how is risk controlled?
