Hi, is there a native function (something like 'sc.ChartbookIsOpen()' ) that checks for existence of a particular chartbook? Alternatively is there an object array of open chartbooks that my code can loop through to find all open chartbooks? If not, how do you recommend confirming the opening of a chartbook after using 'sc.OpenChartbook()'? Many thanks!! |

No, none of this is supported. We will have to see about adding something more in this area later but we are not going to be able to get to this for a while. You can check back in about a month.

Hello! I recently encountered this need for one of my Custom Studies. I cannot find any information about detecting with ACSIL if a Chartbook is open in an Sierra Chart instance. Is something like this in your roadmap now? Greetings, PS |

I don't understand your use case, but even if this API existed, it follows a pattern of not providing useful information. The user could close the chartbook right after your call to determine if it is open. They could rename some other chartbook to the name you are looking for, or rename it and then you can't find it, etc. Many boundary conditions. A better pattern would be to perform the operations you expect possible if said chartbook was open. At least that's my 2 cents... |

I ended up using a global variable that was set by a study in the "child" chartbook after it was opened, and checked by a study in the "parent" chartbook. Both studies needed to be in the same file. There are plenty of posts on this support board regarding "global variables" if you get stuck. For my use case, it was enough to increment an integer, but an SCString could also probably be stored in a global variable (not tested) & then compared with the name of the chartbook just opened. Psuedo-code would be something like: SCString global_ChartbookName = "";
ParentStudy{ // 1) open chartbook with name "chartbookName" // 2) on subsequent code executions, // - check global variable for value // - if value exists, check for match with "chartbookName" // - if match, do something... } ChildStudy{ // set global variable to chartbook's name } |
