Hi, can you offer a colouring method based on a comparison of the Ask Volume minus Bid Volume (Delta) at a price level in comparison to the Delta of the entire bar. |

There are a few options that already exist that may be what you are looking for. Refer to the following information: Numbers Bars: Background Coloring Based on AskVol BidVol Difference Percentage of Max Dominant Side and here: Numbers Bars: Background Coloring Based on AskVol BidVol Diagonal Difference Percentage of Bar Range For the most reliable, advanced, and zero cost futures order routing, use the Teton service: Sierra Chart Teton Futures Order Routing |

There is no option which compares delta at price against sum of all absolute values of deltas across the bar. This makes sense as avoid the problem that you have at least one dark shade at each bar (with the largest delta). I would like to avoid situation that very small delta at price is dark shade at least once as it is the largest one at the bar. To make it comparable delta at price needs to be compared not with the largest delta at bar but sum of all absolute values of delta across the bar. For small and widespread equally deltas at each price you will have light or mid shades. Dark shades you will have only for price where delta was sigfnicant compared to the sum.

Just to verify, as there are lot of ways to do the calculation. You would want to have the exact same calculation as is done for the Based on AskVol BidVol Diagonal Difference Percentage of Bar Range, but not done on a diagonal. Let us know for sure that this is what you wanting and we will see what we can do.

I think we talk about different things. Please have a look enclosed. I prepared explanation in excel file with all the calculations. The same should be for total volume at price compared to total volume at bar (in percentages). You only have for actual with absolute thresholds which does not work in 24/5 markets. In percentages it is better as focus on relative change. If volume is widespread equally at each price level, colouring is the same for each price level whatever the volume, small or big. |

What about below new method which is less difficult in application to proposed above? New method: This background coloring uses a Percentage Value. The percentage is based on the Ask or Bid volume at a given price in comparison to the total Ask or Bid volume across all prices for the bar. For the Ask: Ask Percentage = Ask Volume at given Price / Total Ask Volume within bar. For the Bid: Bid Percentage = Bid Volume at given Price / Total Bid Volume within bar. Any other idea which avoid dark-shades on each bar, even with low volume, equally spread across the bar is very welcome. |

Ok. I will play for a while with a few options available and let you know if any.

Hi, I think that Sierra Chart misses to combine percentage logic with actual one by "AND" condition. Percentage logic is fine. However, if you have low volume bars it is still shown in range up 3 colour. You have always the highest value in the bar, no matter if it is 5 only (the rest is below 5). This 5 will be range 3 color. It does not make sense for a trader to light low volumes even if it is the highest in the bar. I would add "AND" condition to set thresholds from what value it can be range 3 colour. The whole idea is to use mix of percentage and actual approach when volumes are considerably high and at the same time filter out all low volumes. Using only actual approach is also not very well because market volumes change from hour to hour and it is difficult to catch a feeling of the market by the colors if the size of volume is much different (at the open, during the RTH, ETH etc.) Let me know if I am clear. Is it possible to add "And" condition? |
