'easy rider'
By definition; any trade at ask is a sale, because the order was to buy at the highest wanted price and vise versa for a trade at bid, it is a buy, because someone that owns stock is letting it go for the lowest price requested. The person placing the order is buying low and the person trading is selling high.
It becomes hard to remember , because for every buy there is a sale and every sale there is a buy.
(Try to remember buy low / sell high. Heard that before, it's an easy way to remember, bid low /ask high.) Matters not the size of the trade!
Sorry if my post saying hedge guys are selling on EOD trades above the ask confused you. It's kind of a special conclusion, I came to. To understand why those trades are happening.
Doc's explanation on institutional funds buying is the correct evaluation of trades at ask. But I didn't see that kind of trades being reported.
So I took liberties, with my experience of specialists, buying from a large customers, to maintain a good relationship and came up with the theory. Hedge guys are selling out at highs.
IMO Standard business practice, keep your best repeat customers, by servicing their every want and need! Loose short to gain long!
It's only a guess!!!
