HSIC, Henry Schein Inc. - Ready to Breakout

HSIC
Analyze it as an Ascending Triangle or as a Head and Shoulders of Continuation...what we focus on is simply the level of resistance, in which either the price breaks or bounces, and depending on what happens we operate or wait.
At the end in this case if we define it as Ascending Triangle the reading of the pattern has highs of equal level and higher lows. If we define it Head and Shoulders of Continuation the Neckline is perfectly horizontal and the reversal has not happened and therefore the trend should continue.
How do we know that this operation works?
Simple. Backtesting analysis of the past.
What confirms the goodness of our operations over the years? The comparison of real results with those parameterized by the Backtesting.
Everything else is a matter of discipline.
