Post From: Trying to automate a scan for watchlist symbols at the start of every new bar

Hi all, in a nutshell I'm trying to automate an intraday bar chart data download every 30minutes at the start of a new bar. I'm attempting to do this via a scan for a bunch of stocks which I have set up as an associated watchlist, attached to a chart. I have a custom study ("TimeAlert") attached to the chart (simplified code is shown below), which achieves this to some degree. So when a new bar opens, the scan starts, but as the scan opens each of the charts in the watchlist, each time a new chart is opened, the custom study kicks in again and again and starts a new scan, so its a never ending loop of scanning! Can anyone think of a way to achieve this please? I've been round & round in circles on this one and any help would be greatly appreciated! Regards #include "sierrachart.h" SCDLLName("TimeAlerts") SCSFExport scsf_TimeAlert(SCStudyGraphRef sc) { // Set the configuration variables and defaults SCString msg; if (sc.SetDefaults) { sc.GraphName = "TimeAlert"; sc.GraphRegion=0; return; } // Log the current time. SCString TimeString = sc.TimeToString(sc.CurrentSystemDateTime); // Limit to restrict execution of studies to when a new chart bar is created... int &LastBarIndexProcessed = sc.GetPersistentInt(1); if (sc.Index == 0) LastBarIndexProcessed = -1; if(sc.Index == LastBarIndexProcessed) return; LastBarIndexProcessed = sc.Index; sc.AddMessageToLog(TimeString , 0); sc.StartScanOfSymbolList(1); } |
