Yes you have been to strict interpreting TA & charts lately.
There are rules of thumb for non chart pattern expectations and personal rule of trading. But actually I don't know of one rule for TA & charting. They give projection and are evaluated on expectations based on history. A chartist paints a picture from patterns, not templates. There is no exact. It's an art form.
Think of your problem today, as the fact that one pattern begets the next one. With your question, you see a failure which now has created another pattern. The last pattern is always the one to rely on. Many times you see more then one pattern in a stocks price movement. Trust the last one.
Just so happens this one became an ascending triangle from a ascending triangle. Doesn't really matter if the pattern before failed or not. Trade what is now!
