I have watched this trading pattern before and honestly think its a bad sign for Parkervision - If she can't hold 4 where will she go next? On the coins flipped side if she settles in at 3 it could be worth increasing ones share position at the lower cost
Yeah, PLEASE set up lots of stop-losses! I love scooping up cheap stock when a market-maker/mover gets hungry, throws a few thousand shares at the market on a thin day, triggers your stupid stop-loss prices, and all of that stock comes flooding into an offer-thin market as MARKET PRICE ORDERS! Some of the best loading up bargains we longs ever get are caused by dumb standing stop-loss orders. (Take this morning, for a great example).
