Quote from box:
I don't know if it's a trick or not, but I have noticed when trading stuff like KLAC / EBAY / QLGC that from time to time, there will be an ISLD / ARCA or other ECN, with an odd lot showing, and if it doesn't fill right away, others will soon join at that price. So it could be from time to time 1 share, 50 shares, or any other odd lot could control the price (as opposed to 100 shares). Anyone else notice this?
yes. KLAC does that alot.
