I'm pretty sure if you get someone buying or selling enough volume it doesn't matter what the chart said might be going to happen. For example no matter what the charts say if I was to buy 20m shares over the next 2 days I'd be making my own chart. Equally if I decided to sell 20m shares over the next 2 days I'd be making my own chart. It wouldn't matter what the charts said before I started buying or selling, my buying and selling would be enough to form a new trend, even if just temporarily. Even those that beleive in charts would have to agree that if someone big enough makes a decision on a given day to either buy or sell then most bets about what the chart said was likely to happen are blown out the window. That was my point.
