Hi I wonder if RecalculateChart updates correctly the arrays of a study that I fetch using GetStudyArrayFromChartUsingID. More precisely : I am trying to change the parameter of another chart study and get the result in one his subgraphs. I use SetChartStudyInputInt and can confirm the parameter was changed using GetChartStudyInputInt. I then use RecalculateChart to make the computation of the study. But, when I get the results using GetStudyArrayFromChartUsingID I continue to get the old subgraph values, as if the recalculation was not done, or as if the arrays of the subgraph were not updated. I can give a code for test. Please advise. -- W |

The recalculation happens on a delay. It happens the next time the specified chart performs an update.

Thank you. Is there a way to force the refresh of a chart ? I am using non connected instance for the study I am working on (sort of back tester..). -- W |

There is no need for that. The chart will get calculated at the next update whether connected to the data feed or not.

Thank you I have no doubt the chart will get updated at some point but I need to control that since I will run that many times, because I cannot wait randomly for the chart to be updated, and because I do not know when it was finally updated. The core logic is : Loop on a very large set of parameters scenarios Change the parameters using sc.SetChartStudyInputInt and it works well. Recalculate chart using sc.RecalculateChart, but at this point not working for me because call is asynchronous Get data and store it for later analysis, which does not work because the recalculation is asynchronous. End Please Let me know if I missed the sc.Recalculate logic of if you think I missed a function in the ACSIL doc that could help me do this kind of back tester. Thank you.

We would have to add a function to do an immediate recalculate. We will see about that. We can do this, but we are not sure if under certain scenarios it could lead to some unexpected problem.

This function is available in the latest release: sc.RecalculateChartImmediate(int ChartNumber);
