I think you are being a bit alarmist. Don't worry, there are counteracting forces which also work in the absence of "blockbuster news". LOL. Try the 500k order via the ECN. That is a direct signal to shorts and is also something which can cause covering in and of itself if it doesn't go away. This is a battleground, "news" simply is convenient for retailers to believe they know what is going on. The real game is played in advance of "news" and setting up positions. Insider purchases are case in point. Much empirical research shows that insider purchases in smaller market cap companies can be indicative of expected, material news anywhere from 6 months to 2 years beforehand. Don't try to think to much. Just process the indicators.
