I believe it. I’ve seen somewhat similar action on the buy side with seemingly automatic orders jumping above my bids by .001 or so. Has to be algorithmic as it was instantaneous after my bids were placed.
You owe no explanation why you are selling. It is your money, your business. Sell away and rejoice in your profits. Any one that chastises you is not being honest.
*Last post today, can't wait for the MB penny stock authority to toss his boring same, lame word salad at me again. SO.....you can't count real money until you sell. No guarantee of a buy out.
