Hi, I noticed the following. I open a chart DOM with an update interval of 50ms. I insert orders and don't notice any glitches. Then, I open a 15-second candlestick chart with an update interval of 3000ms to prevent any impact on the DOM chart. When I return to the DOM chart and insert new orders, for a few moments, the DOM freezes. If I minimize the 15-second chart, this doesn't happen, and if I change the update interval of the 15-second chart to 50ms (the same as the DOM), there are no freeze or glitch issues. I don't understand how the update interval of a chart can affect the DOM, since I had understood that non-priority charts should have a slower update rate. Obviously, I can't leave the chart at 50ms because I need to add studies. Please, what could be the reasons for this? how are they correlated? |

right in this guide (Chart Trading and the Chart DOM: Improving Performance Of Chart / Trade DOM) it's said: "Alternatively to the above, you can use a larger number of charts per installation/instance of Sierra Chart, however use a higher Chart Update Interval for them. In this way you can have a larger number of charts in a single instance beyond what we are recommending above. The Chart Update Interval you may want to use could be 1000 or 2000 ms. Or higher." does it mean we can run multiple charts with studies in the same instance along with the dom as long as their update interval is higer? |
