A theory about Major Distribution Day; called a 90% down day is that a Major Distribution Day never comes along, so once the first one happens, there’ll be at least another one, unless a Major Accumulation Day kicks in, then the Major Distribution Day has to be recounted.
A theory about magic number three is, the 3rd time usually is different.
Now look at the chart, 2 previous Major Distribution Day, both cancelled by a Major Accumulation Day thereafter. Now this is the 3rd time we have a Major Distribution Day, so the question is: Will the 3rd time be different?
Here is a Thinkscript to identify MAD's and MDD's. Both Accumulation and Distribution days. They don't happen all the time. Running this every night will make them obvious.
