pullback or crash

GC break the support with very high volume and come very close to the next res . but since the selling contract are becoming bit lower it's probably a sign of a pullback.
so if the market break this support with high volume soo it's a sign of a downtrend coming. else it's will make a pullback until touching the res .
the probabilty of pullback > the probabilty o crash : strong support not easy to break but as we know their is always suprises and we should be always ready
