I was in the chat room this morning and myself and Nitro were discussing this with shortseller. I explained to shortseller that his tape reading skills were severely lacking. Although I don't trade listed stocks anymore, for 2 years I did and was quite consistent with it. I tried to explain to shortseller that size bids are there to be hit and size offers are there to be lifted.
True, in this situation he did not provide enough info. If that bid was stepping up and the stock was strong and near the high of the day, it might very well be a buyer. However, when there is a real institutional buyer or seller in a stock, they never show their hand until they are almost done.
Think about it, a real buyer is not going to say to the world, look at me, I have so much stock to buy, please lift all the offers so I have to pay up to get my stock. No, he is showing that bid because he has been buying the stock all day with no bids and now, that is all the stock he has left and wants to get hit. And he will get hit.
I told short seller, I use to love to see those bids. I would sell into them hard all day long provided the stock was weak and I knew there were sellers in the stock.
Trying to buy stocks with large bids and sell stocks with large offers is what we use to call a mook. A mook is an idiot that jumps in front of size only to see that size hit and then quickly is sitting on a losing trade. When I daytraded listed stocks, I use to look for patterns for the buyer and the seller. This took me months to learn how to do. Most of the time, especially with small and mid cap stocks, you would see 100 shares on the bid or maybe 300 shares on the bid, and it would be stepping up all day long. You never see the bid get hit, or if you did, you would see 300 shares bid, then 2k shares would go off at the bid and he would still be there with 300 bid. Very classic. This guy has a lot of stock to buy. And he would never show his hand.
When a large offer would show up, the mooks would quickly run to sell. The buyer would be there or the specialist buying all the cheap shares from the mooks. When the mooks were done selling, the 300 share bid would step to the size offer and suddenly the offer would get lifted in one print, bamm, gone. Now that 300 shares is stepping up again and the mooks are all bitching about how the stock is manipulated. This would go on all day every day. The mooks would never learn.
Like I said before, in this example, there is not enough info to go on. If the stock is strong and near the high of the day, I would be looking to buy the stock. But in general, even if the stock is strong, if he is showing size, it means that is probably all he has left and he will be done and the stock will trade lower the rest of the day.
Remember, the reason the buyer is showing his hand is because he has already bought all his stock. He will never show his hand if he still has stock to buy. Would you? Now I know what some of you guys are thinking, I'll just buy the stock and put a stop on the bid. OK fine, you and the other 10k daytraders out there all have your stops on the bid. You guys know what a stop is right? It means when Goldman comes in to hit that bid for the whole size, your orders are not filled yet. Now the stock is going into free fall and you have a sell market order out there. I can't tell you how many times I've seen stocks gap down .50 in this situation. If you think you are going to get any of that bid you are nuts. You are not going to get a single share. You will be filled down .50.
Anyway, that is my response to shortseller. I'm sure Don Bright or others on this board that have any kind of tape reading skills will say the same thing.
