Firstly, the HHV() and LLV() commands don't make sense with negative
numbers b/c the number following the array is for periods not for
reference. The negative/positive number thing is for Ref() and
ValueWhen() as you can see from the help files.
That being said, I am goin to give it a go with the code you are
looking for (btw, I didn't get to see the chart but was doing
something similar not long ago).
One note: using HHV() and LLV() will always pickup the current bar so
if you are looking for a BO you must use Ref().
SwingHigh = Iif(H>Ref(HHV(H,5),-1) AND Ref(L,6)<Ref(LLV(L,5),5) AND
H<Ref(HHV(H,5),5),1,0);
The first condition is to see if the current High is greater than the
five previous highs. The second condition is to see if the low six
bars into the future is lower than the next five lows. The third
condition is to ensure that the next five bars do not have a higher
high than the current high.
Finally, SwingHigh will equal 1 when these conditions are met and 0
when not.
