Hi. The following list contains some improvement proposals for the Sierra Chart Trading DOM. Some of them are essential imo. 1. Recent Bid Volume Bars and Recent Ask Volume Bars The Volume Bar Width is calculated separately for the Bid and for the Ask side. I think that makes no sense. Lets say the largest Bid volume traded is 25 contracts and the largest Ask volume traded is 500. In this case the width of the Volume Bar with 25 contracts at the Bid side is the same as the Volume Bar with 500 contracts at the Ask side. Because the width is calculated separately. The improvement would be to calculate the width of the Recent Bid Volume Bars and Recent Ask Volume Bars based on the volume traded on both the Bid and Ask side. 2. Recenter Line and Recenter function The recenter function recenters the Trading Dom based on the last traded price. At least I think it does. A better way to do it would be to recenter the Trading Dom based on the Ask or Bid price. Lets say I have 3 Trading Doms side by side. I like to watch their relative movement. I recenter all Trading Doms. As the last traded price is used to recenter the Doms and the last traded price is either on the Bid or Ask side the recenter line is not always horizontal throughout all the three Doms. 3. Cumulative Last Size 3.1 The Trade DOM Cumulative Last Size Background should fill out the whole cell. It was changed lately to a larger fill which is better than before but it still does not fill the whole cell. 3.2 The logic how the Cumulative Last Size Background is displayed could be optimized. Currently there is a determination between the Background color of a Bid(e.g. red) or Ask(e.g. green) trade. There is another vendor which does it differently. I would prefer the logic of the Cumulative Last Size background color based on uptick, downtick and same tick. So three different background colors and three different price colors. The uptick color (e.g. green BG and white text color) is the first traded volume at the ask. After this first traded volume the cumulation of additional volume at the ask is displayed as the same tick color( white BG with black text color). If in this situation the offer gets lifted and the next volume traded is at the Ask side, it would still cumulate as the same tick size (e.g. white BG with black text color). I hope this logic makes sense. I added two pictures which show what I mean. The first picture shows the Uptick logic followed by picture two which displays the cumulation of one more contract coloured in the same tick logic. |
