As with entries, the Turtles calculate their stops according to the risk factor N. No trade could incur more than two percent risk or 2N, as 1 N of price movement represents 1 percent of the account equity.
Stops are mandatory for the Turtles systems, and they should be strictly followed and never be changed.
If additional units were added, the stops of the earlier units were raised by ½N. This means that all the stops for the current position would be placed at 2N from the most recently added unit.
Since the Turtle’s stops are based on N, more volatile markets would have wider stops but should have fewer contracts per unit.
