The sellers knows that OVTI will be much lower by the end of the next week. The buyer is looking for a quick pop to exit for 5 to 10 pennies gain in the morning. We already have seen the buyer to buy 400 shares at $14.10 to imply that OVTI is going up or a good news in the way. Basically to fool retail investors. Some suckers will buy from this buyer to make him $50k richer on Tuesday. On the other hand, this new buyer is Tuesday's most seller and his selling will keep the price down like last Friday. OVTI will drop sharp after he is done selling his shares.
