Green lines on my chart (not the very long ones) were trend lines on my Bollinger's taken from the 15 minute as I felt if anything was going to happen those lines would have to break to confirm. My Bollinger's are set 20, 3. Sometimes I will offset them as well because they capture the peaks, trough's, and break opportunities better. Still have to wait and see whether this is going to be a good short, or, whether market shoots back up again.

Remember that all the clues I'm spotting as to what to watch and what appears to work and may work again have really only been discovered in month of February. You need to get a computer to test the rules and to find and keep track of the best MACD to be using. That way you may find those rules work all of the time and can be commercialised. Good luck.
