Is the address of the ref passed into the study consistent throughout the study’s lifetime? The use case I have is using the pointer as a key in a global map and removing it on LastCallToFunction. If the address can change (for example due to a reallocation) then I’d rather not use this approach. Thanks. |

No, it is not constant or stable. We would expect that it changes when you open the Chart Studies window and then press either OK or Apply. This would be the only reason we can think of. And certainly it would change when you close a Chartbook and reopen it. Sierra Chart Support - Engineering Level Your definitive source for support. Other responses are from users.

But in those instances, LastCallToFunction would be set right? I.e before the reference becomes invalid, you set LastCallToFunction |

No this is not true in the case of when changing studies through the Chart Studies window: But in those instances, LastCallToFunction would be set right?
This will not become true in that case and we have confirmed that the address of s_sc does change. Sierra Chart Support - Engineering Level Your definitive source for support.
