And what we are talking about was what, 5 hours?

Broke 0.00 level @ 108pm, bottomed @ 129pm, had a more than 50% bounce @ 148pm that didn't hold, a 2nd higher low @ 234pm that did.

So it is however you want to look at how long it took. Me an hour or so. Because almost all of that sub zero volume was on the initial down move.

I think we're addressing different things. Time Negative vs Time of Reversal Bar.

It didn't trade positive again until 7pm at night, after the reopen.
So it was negative for the last 3hrs on the 20th and for the first 2hrs on the 21st.

Hence
