L2 service might be helpful IMO.
Let me loosly define walkdown for you in 10-seconds.....when 500k takes it from .004 to .018 and then 50k takes it back down with 5k at each penny level on the way down to .01, that's called a walkdown but you are free to call it what you want.
Look at the other posts if you do a board search, looks like I'm not the only one who also believes 'low volume' walkdown.
Look, not here to promote or defend CHADQ, it's a Q play, you are acting like none of us notice that lol. But I'm done here, GL pointing out that it's in BK.
