Can anyone help me understand the motive, the situation of these common tape reading setups? 1. Show bid- prints the middle-never hits the bid- prints the offer -and offer become bid .......GO LONG (fill an institutional order?) 2. Show offer- prints the middle- never prints the offer- prints the bid- and bid becomes the offer.......GO SHORT (does that mean it is close to getting to the end of an institutional buyer, and a reversal is going to take place?) 3. prints the bid again and again but does not go away- prints the offer and offer becomes bid...GO LONG (is this filling a sell order, and after the order has been filled, it prints, and a reversal takes place? ) 4. stock shows a very large offer and a very small bid. Eventhough the bid it hit, the bid does not go away. The offer starts to print and then the offer becomes bid....GO LONG 5. stock shows a very large bid and a very small offer. Even though the bid is hit, the offer starts with the same small size. The bid starts to print and becomes the offer...GO SHORT.
