Did play RTNB this morning after the first volatility halt on the big initial spike. Once it became unhalted I got in on break of the HOD and previos Halt price of 1.60 and then wanted to sell it up to 1.75 natural resistance......It moved so quickly so i ended up getting filled at 1.65 and selling at 1.73 for quick 220 bucks. Then just watched it the rest of the day but never reentered
