I'm trying to set up an alert for when the price high / low reaches the top / bottom Bollinger band and I'm not sure how to set up the condition: for instance High (+ 5 ticks) Equals Top BB, OR High (+ 5 ticks) Cross above Top BB?
Also, if the price pushes higher and pulls back only after it went 10 ticks over the top BB, would I still get the alert, since at the time it went over the BB, that was the Close, rather than the High? I'm not sure if the Close is considered to be also the High on new bar Highs.
I am unsure about the Cross Above Look back period: if I need the alert as soon as the current bar price gets within 5 ticks to the top BB, shall I set the Look back period to 0? I see the default Look back is 1 - does that mean previous bar?
Thank you
