TegsPal, thanks for the question. In my opinion, no single indicator can paint the whole picture but sell imbalances tell me a stock is under pressure, which significantly limits upside movements.
In the case of INT, If you combine this with the fact that a PP at significantly lower prices became free trading, it told me to stay away.
Having said that, I missed both the dip into low 90's and the fast rebound - but I don't mind that because disciplined traders don't 2nd guess their calls. You learn from them but don't 2nd guess.
Hope this helps!
