RE:Buying strategyThe 100 share buy or sell order every 1min, sometimes 30 seconds, sometime 2 mins -- typical of an "institution" who puts in an order to buy or sell a specific % of market volume...and at a certain average trading price of the day....you will see the orders accelerate or decelerate based on the general volume and pricing trend -- its a way that managers and institutions can buy or sell and tell their bosses that they got a good average price.
