I have learned they can be uncanny at times. But, aside from the 3850 target, I thought the BRL was very revealing. You're right that it would be a huge breakout if it were to be taken. The interesting thing is I can't duplicate it on a candle chart. There is no corresponding resistance line that I can find.
Excellent example of why one should do more than just one thing. I think the 50 box is also interesting as a tighter view.
