What is Turtle Trading Rules?

Turtle Trading Rules displays its configured entry and exit range calculations on an MT5 chart. The resulting conditions are marked with colored arrows and lines.
The marks are generated from the two selected periods. They should be considered alongside the wider chart and completed candles rather than as a guaranteed outcome.
How to use Turtle Trading Rules

Compare the two range periods with recent highs, lows, and the surrounding price structure. A shorter period reacts to a different span of history than a longer period.
The settings window contains two period inputs: Entry Period and Exit Period.
Where it helps
Entry Period controls the history used by the first range calculation.
Exit Period controls the history used by the second range calculation.
The indicator has two direct period settings.
