Will you share your insights about how the book, of the Minidow future for example, works? What I could see so far is that when we have an upmove, the tenth level of the ask is more crowded than the tenth level of the bid, contrary to what I was expecting. I couldn't observe all the levels, but it seems that on the tenth level volume works as a magnet, "attracting" the price, higher or lower, rather than pushing it. In other words, during a rise, the bigger volume (not intended here as executed trades) almost all of the time on the tenth level of the ask, and viceversa. When the price doesn't move, it varies. I don't know how all this could be useful in my trading, because I am not saying that when we have higher quantities on the tenth ask level, we start rising. I am only saying that when we rise we have higher quantities on the tenth ask. Maybe one way of using this information is that when we see that during a rise the quantities on the tenth ask are decreasing (I mean the ration between the quantities of the bid10th/ask10th), the rise could come to a halt. And it does happen that way, but this doesn't exclude that such quantities will increase again and the rise will continue. So I would like to learn some more about this, if anyone wants to share their views on this topic.
