Turtle System 2, tested on 29 markets

Watch the test, then see every market.

1983.

Two famous traders made a bet: can anyone learn to trade?

They trained a group of beginners: the Turtles.

The rules

In. The price breaks its 55-day high: buy. Its 55-day low: sell short.

Add. Keep adding as it runs, up to 4 units, each risking 1% of the account.

Out. A 20-day break the other way, or a stop two daily moves back.
