Ultimate Bollinger Bands by @DaviddTech

This strategy uses the Ultimate Bollinger and Aroon indicator.

The logic behind the code is

* Enter long :
Aroon up is below the 20 or lower line in settings.
Aroon down is above 70 or above line in settings.
When close crossover the lower Bollinger Band we take an entry
SL is %
TP is % of if Aroon up is below the 70 or lower line in settings.
Aroon down is above 20 or above line in settings.
When close crossover the upper Bollinger Band

* Short :
Aroon down is below the 20 or lower line in settings.
Aroon up is above 70 or above line in settings.
When close crossunder the upper Bollinger Band we take an entry
SL is %
TP is % of if Aroon up is below the 20 or lower line in settings.
Aroon down is above 70 or above line in settings.
When close crossover the lower Bollinger Band

Settings I used to get the results below :
