Not always, sometimes it’s two or three days before they sell. That s when they start asking questions when they’re selling near the bottom of it they say who the heck is this trader who buys just one share. Was that a typo or something! So you might have to buy a couple shares once in awhile so they don’t zero in on you.
When they wait a few days I’m guessing they’re moving the trading range one way or another so you have to figure that in too for what they might do the next day depending on what direction they’re bringing it.
