I have to admit that I'm new to trading but use each opportunity to gain more knowledge. There is one thing however that puzzles me. I do my study, check the indicators, volume, tape etc. Tape is moving at nice pace and I stock is trending up. I place my order. It gets executed and suddenly like I opened door to hell. Massive sell out. What's going on? I happened to me couple times already. Somebody please enlighten me?
