Hi, As you can see in the picture - there seems to be a difference in how the composite VBP study is displayed in separate charts in the same chartbook. They are both set to show last 5 years data. You will see on the left chart there appears to be a low volume area, although on the right it appears to show higher volume. I have removed and readded the study and the volume profile still displays the same. I can supply the .cht file if required. Thanks Date Time Of Last Edit: 2016-09-22 14:24:48

One thing you will need to do is to scroll through those five years of data and see if you notice any differences with the chart bars between the charts. Refer to: http://www.sierrachart.com/index.php?page=doc/VolumeByPrice.php#VolumeProfileDifferences Also are there more than 100,000 bars in the chart?

Hi, I went through all the settings and they are the same. I have changed the renko chart to candlesticks and set the periodicity to time based, as I did with the number bar chart and this has made no difference. If I duplicate either chart and change the settings the vbp profile does not change either. How can I tell how many bars are in the chart? Are you able to add this study to compare how yours looks, that way I can tell which chart is displaying incorrectly. Cheers |

Did you do this: One thing you will need to do is to scroll through those five years of data and see if you notice any differences with the chart bars between the charts.
This is essential to understand why there might be a difference. Are you able to add this study to compare how yours looks, that way I can tell which chart is displaying incorrectly. We would need to get a Chartbook containing a single chart so that we can provide you a chart image of what we see. Here are instructions: http://www.sierrachart.com/index.php?page=doc/PostingInformation.php#ProvidingChartbookSingleChart The Bar Numbering study can be used to determine how many chart bars there: http://www.sierrachart.com/index.php?page=doc/TechnicalStudiesReference.html#s254 Sierra Chart Support - Engineering Level Your definitive source for support.

hi, according to the bar numbering study, the left chart (renko) has 150122 ad the number bar chart (right side) has 4552 bars. maybe my understanding is not quite right - the charts might not actually show 5 years of data, although I was hoping to show composite profile data going back historically. Is there a simple way I can compare the 5 years worth of data? I have attached seperate chartbooks for the 2 charts that have differences in the composite data. Please let me know if you need any more information. Cheers |

We do not understand why you would want a five-year Volume by Price profile on two different charts. This is a very intense calculation with CPU and memory. Do not bother with it on the Renko bars chart that you have. The accuracy is going to be degraded because of the large number of bars. Refer to: http://www.sierrachart.com/index.php?page=doc/VolumeByPrice.php#AlgorithmToMinimizeCPUAndMemoryUse The chart bars should be set to 1 Day per bar or at least not less than one hour. We looked at the chartbook_test2.cht Chartbook and it is only loading 30 days of data. Use the Continuous Futures Contract feature to load five years of data: http://www.sierrachart.com/index.php?page=doc/ContinuousFuturesContractCharts.html Sierra Chart Support - Engineering Level Your definitive source for support.

I use the composite data to mark out areas on rejection on the longer timeframe chart (chart1), then move to the shorter timeframe (chart2) which I use the number bar study for execution away from these levels. When I noticed the difference displayed in the 2 charts I could not confirm which was correct so, therefore cannot tell if I am trading away from rejection into acceptance or not as the composite data was not the same. I like to have the profile on the number bar chart, as this makes it more visually obvious what my areas of interest are (I have the dom and this chart side by side). 5 years is probably a little overkill. Based on your suggestions, I will remove the profiles on these charts, and add only to a 1 hour standard candle chart chart (daily would be too high periodicity), I'll mark the areas of interest on my renko chart, then will manually reference this when reading the number bar chart |

if you can suggest an alternative/recommended way/study to show what I am after I would be interested to try it, or is what I am doing the best method? would it help if I created each chart from a 1 hour chart with 3 years composite profile?, I could then duplicate the chart and change the periodicity as required? I have checked on a range chart and it appears to show the same information in the composite profile as the longer timeframe chart I created it from. Date Time Of Last Edit: 2016-09-27 09:47:27
