i see what you mean about knowing if the 1000 shares the specialist is refreshing/ in other words if a specialist has 1000 at the offer at 49.99 and everytime someone hits it for 1000 or even 2000,1000 shares still shows up. however,id some guy then hits iut again for 200 shares and 800 show up,it would be a good idea tio immediately grab those remaining 800 shares on the assumption that the specialist just unloaded a big order at 49.99 and is done. this is usually good for .20-.30 cents. now with only showing 100,its much tough.what i do is this.if 100 shares are offered at 49.99 and as you see prints of 1000 or 2000 at that price and still see 100 shares,its an obvious refresh. i would then have my buy order for lets ay 1000 shraes at 50.03,so when the specialist is done at 49.99,i immediately hit buy at 50.03 ensuring that i get a good fill and then sell higher on the ensuing squeezewhat can happen is the specialist just initiates a new refresh at a few cents higher at 50.05 and that can suck. nothing is fool proff but i have great success doing this.this works weell on a momo stock with news.
