$UB Top one changes hands, surges high then slows down

Not a continuation of a strong trend
30 minutes ago, top one NIL 120%
Now UB only remaining at 18.79%
Heat drops off sharply, indicating funds are switching
OI 24h +46.3%
But in 1h from +9.1% to -11.2%
Fee rate shifts +0.005%, longs paying the fee
Contradictory evidence is clear:
If OI increases again, and the premium turns positive
And volume breaks through 0.17643
That would indicate longs are regaining control
$UB Is this a shakeout, or the last lap of the top one relay?
