Of course, no worries.
Ind_A = Daily Range of an individual Bar (diff between High & Low)
Ind_B = Smoothed version of the above
In this example I want to find patterns where:
1. on first bar & last bar of pattern the Daily Range (Ind_A) is
greater than the Smoothed Daily Range (Ind_B). [Increased Volatility]
2. Each of the middle bars in pattern have a reduced Daily Range.
Ind_A < Ind_B [Reduced Volatility]
However, I also have some other ideas which are similar but rely on
different indicators so hence my wording in my original question.
Basically, to allow me to use this code as a template for my other
ideas, I'm trying to code:
1. First & Last bars in Pattern = Indicator_A > Indicator_B
2. Each of the middle bars in Pattern = Indicator_A < Indicator_B
Hopefully, the above makes sense.
Thanks again for your help with this one....
regards,
Chorlton
