This pattern (see chart) rarely occurs and when it does, the break out is usually the sum of the ranges of each day added to the base (in this case the Mariner low).
We had the "Mariner drop" on Mar 2nd followed by 6 subsequent inside days, then an outside day and today (if it remains in the range) another inside day while at the same time squaring out to price.
A classic and rare Gann pattern which if it gaps away on Monday, we should be looking at a target of the sum of the ranges + the base = $ X.XX within the same time period (9 days).
I am sold on the tech so what is left to nail is the target price.
