ACSIL Delay processing until all data is downloaded?

I'm in the process of porting my code to Sierra Chart. This is generally going very well and my studies are functional, it has been a pleasure to work directly in C++ without crossing proprietary language boundaries. My studies require the instantiation (and termination) of custom networking classes which I would like to finesse to ensure this happens only once and at the correct time. I have encountered an issue that when a Chart Book is opened and the charts are downloading data history then my study is processing on a partial data history. I'm using manual looping and would like to delay the processing of the chart data until the history has been brought fully up-to-date with whatever data is available to be downloaded for a given symbol. I have tried this, but it doesn't seem to be the answer: // Do data processing .....
// sc.ChartIsDownloadingHistoricalData() // The sc.ChartIsDownloadingHistoricalData() function returns TRUE(1) if the chart the study instance is on, // is downloading historical data.This function returns FALSE(0) if historical data is not being downloaded. int wait4Data = sc.ChartIsDownloadingHistoricalData(sc.ChartNumber); // Wait until any download activity is complete if (wait4Data == 0) { ... do stuff } Is there an approach to accomplish the aim? |

We apologize for the delay here. We do have a very heavy support load and these types of requests do take time. Why is this not going to work for you?: sc.ChartIsDownloadingHistoricalData This is the exact function you would want to use. The study function should be called when the historical data download completes. There is also this flag you can check: sc.DownloadingHistoricalData Sierra Chart Support - Engineering Level Your definitive source for support. Other responses are from users.
