I find these two indicators very accurate for long term trend analysis.
The weekly '20 Close BB' has been very good for following trend changes on the daily.
The 50MA has been support 4 times before and now we have broken bearish we are at the back test stage to confirm if it is now resistance.
So far we are rejecting from the 50MA however bear volume (follow through) has not followed.
We may find support on the daily and form a higher low and go again however if we form a lower low on the daily I suspect the bear vol to follow up then.
