I went through MRNA’s candles and order book, and one line of numbers doesn’t add up.

My take: This isn’t a decline; it’s a dump that nobody wants to catch.
Strange: The 11-11 22:00 candle saw 15,355 lots traded, 8 times the average volume of the previous twenty candles.
One candle plunged from 253.54 to 245 and closed at 247.88; all the selling pressure was spent in that one move.
First red flag: Three hours later, at 01:00, it tested 243.44 again, but volume was only 2.47 times average.
It tested even lower than before, but with less than a third of the volume. That’s not normal.
Clue: For the next nineteen hours, only 50–60 lots traded per hour.
With average volume at 1,100 lots, those nineteen hours were basically devoid of trading.
The reveal: The sellers were the people who chased above 273 at 11-10 22:00 and held on for a day.
All the buyers were low-priced limit orders; volume was pitifully low, and they couldn’t absorb the selling.
So $MRNA is now at 245.92, with MA20 at 247.62 still overhead.
If 243.44 breaks, I’m looking lower; I won’t make a move until it gets back above 248.78.
