I have a study, that draws subgraphs on a chart drawing on bars are initiated by finding a specific drawn object type on a bar and it continues to draw until a condition is met. Basically it is a stop loss level. I add the drawn object to the desired bar and currently I press recalc. There are other reason I do not want all studies to recalc. Can I capture a menu item and then set some sc.'variable' or execute some sc.'function' to accomplish what I am after? If I need to simulate a recalc for this study based on menu item I create, How do I reset/initiate my 2 subgraphs for all bars, or what value do I place in each bar as I loop through them until last / current bar (sc.Index) ? If I change an input on Study-A and press OK, it will recalc all studies on the chart. I've been digging around the online docs Below are areas I read/reread sc.FlagFullRecalculate - to cause a full recalculation of all studies on a chart sc.FlagToReloadChartData All help, guidance and pointers to info is appreciated.

If you switch to manual looping, then something like below would work. You are substituting 0 for sc.UpdateStartIndex only when you have triggered the recalculation. auto& sg_1 = sc.Subgraph[0]; auto& sg_2 = sc.Subgraph[0]; // Set the recalc state via menu item or button // configuredMenuItem would be set when first configuring / initializing the study const auto recalc = sc.MenuEventID == configuredMenuItem && configuredMenuItem != 0; const auto updateStartIndex = recalc ? 0 : sc.UpdateStartIndex; for (auto i = updateStartIndex; i < sc.ArraySize; ++i) { if (recalc) { sg_1[i] = 0; sg_2[i] = 0; } // Various other study code etc } |

Thanks much. I'll try it later tonight. I'm self taught C++ and ACSIL and not full time. Sooo I do fall in holes now and then. Thanks again. JohnR |
