I noticed the same thing when I bought my million. Looking at my account it shows me as having around 20-30 different buys and they are all over the place. I know I didn't place that many buy orders. I have 1.2 million shares and I bought then in lots of 250,000 , 140,000 and the rest were in lots of 100,000 and I had some loose shares that I had purchased in one of the first two lots. I should only have 10 buys. Crazy how it all happened.
This month I have said, "I can't wait until Monday" far too often!
