An entity using REDI as a MM bought about 100k WORK shares over the last 3 or 4 days. When they stopped buying, WORK broke support at 5. Anticipation was for stop losses to trigger and precipitate a quick plunge to about 4.5. There were no stop loss orders and WORK dropped .15 on only 500 shares. A day trading opportunity didn't occur - a total surprise for me.
