Performance Problems with Numbers Bars

I have had extreme performance problems with Sierra Chart for some time when I have the Study Numbers Bars active. I have installed a new Sierra Chart instance and loaded only this one Chartbook. If I want to click on something in Sierra Chart, for example a rectangle, it takes 1-2 seconds until something happens. The same only if I go through the menu above. As soon as I remove the Study Numbers Bars, Sierra Chart runs very smoothly again. |

Cant help you but I have not noticed any performance issues what so ever. Its the opposite - compared to other software. Sierra is very light and outperforms others. Just look at memory usage and you will be blown away how little it is. |

There is no other software open I have tested this extra. Memory and CPU values are actually ok, I have 128MB RAM and a 12 core CPU. Also Sierra Chart itself is on its own hard disk (SSD NVM). I am aware that Sierra Chart is normally very performant, so I am a bit surprised |

I once made a video where you can see very well how the delay is. If you open the Chartbook with a simple candlestick chart and draw a rectangle you can see that it follows the mouse smoothly and immediately. If I go to the Delta Chartbook I can see a clear delay

The first video does not play anything as if it has nothing to play. The second video is very poor image quality. In general refer to help topic 30: High CPU Usage | Inactive User Interface | Poor Performance | Long Time to Load Chart Data | Charts Reloading Often But specifically refer to these sections for things to do: High CPU Usage | Inactive User Interface | Poor Performance | Long Time to Load Chart Data | Charts Reloading Often: 30.5 - Chart Update Interval High CPU Usage | Inactive User Interface | Poor Performance | Long Time to Load Chart Data | Charts Reloading Often: 30.23 - Chart Tick Size and Volume at Price Processing Numbers Bars: Adjusting Tick Size For Larger Increment The first and third ones definitely will help. Also try disabling OpenGL if you are using it: Graphics Settings: Use OpenGL for Chart Graphics (Global Settings >> Graphics Settings >> Other) Also, what you see just may be normal if that chart is redrawing repeatedly for unknown reasons because in that chart there are a lot of bars, and a lot of price levels being shown. You cannot expect Sierra Chart to be high-performance always. There are so many things you can do that will put it under a very heavy load.

I have already gone through all the points you know. The Rectangle is only an example because it is a good way to show the delay. The same applies to the complete operation of Sierra Chart. I did not have OpenGL active. Set ChartUpdateIntercal >1000ms Maybe I cannot expect Sierra Chart to be high-performance always. But I can surely expect from a software that it is operable. I do not know this from SierraChart. In the past it always ran reliably and smoothly.The problem has appeared only recently. I do not have a slow computer and there are enough resources for Sierra Chart, so it surprises me even more. |

But I can surely expect from a software that it is operable. No you cannot. Based upon how you have configured the chart and the performance of your system you can have a problem. We can tell you that chart will present a very heavy graphics load.Anyway, we do see what the problem is and we will implement a patch for this. Basically the chart is being redrawn continuously as you are moving the drawing around. That can happen for rectangle drawings when it is displaying text but there is no text in this case so we will put a small optimization in. But you can expect this issue if there is text. The difference is that you have a lot of bars and a lot of price levels.

Thanks for that. |
