I think the directional volatility indicator has an error.
The strategy summary shows:
Open a new long position at the beginning of the bar when the following logic condition is satisfied:
Directional volatility* (5); the line rises.
Open a new short position at the beginning of the bar when the following logic condition is satisfied:
Directional volatility* (5); the line falls.
----------------------
Open a new long position at the beginning of the bar when the following logic condition is satisfied:
Directional volatility* (5); the line changes its direction upward.
Open a new short position at the beginning of the bar when the following logic condition is satisfied:
Directional volatility* (5); the line changes its direction downward.
----------------------
Thus in all the logics of the indicator
In this way we can only apply ascending volatility when the price rises, but not when the price falls.
