I also searched for a reason for the small breakout that happened before the stock of ING picked up the channel I have described. I conducted a simple trend analysis (red lines). What might have happened is that investors conducted such an analysis at the time, which would have resulted in a three point hit on the support trend. This would have given investors the confidence to engage in massive investments on the stock of ING , as a result of their plots being accurate.
Let me know what you think! I'll keep on posting ideas in the near future!
May the market favor you.
