Topic: bollinger strategy problem

I imported data from December 9th to 11th after that I generated a one minute frame strategy which gave me two indicators, the RSI falls (30) and the Bollinger; concerning the RSI there is no problem on the other hand the problem arises at the level of the bollinger which gives as condition: " The bar opens below Lower Band after opening above it"

then I tested on December 12-13 I got arrows which do not check the condition of the bollinger see the pictures

if we see picture 5 there are 2 cases the first one is OK since it satisfies the both conditions. In the second case it's also  satisfies the 2 conditions but there is no arrows

an other case in the picture 2 where we got an arrow despite it's not checking the condition of billinger "" The bar opens below Lower Band after opening above it"

so i'm confused can any one give me an explication why ? thanks

Re: bollinger strategy problem

The application uses "Previous bar values" in teh logical conditions. Please see more info here:

Use Previous Bar Value
