My requirement is as follows: 1. Draw multiple lines on the chart based on my own condition. 2. Retain line handles or something similar in a persistent array to delete lines when candle body closes through the lines. 3. I want to expose the remaining lines to another study in another chart. So far, I figured out the following 1. I can draw multiple lines using sc.AddLineUntilFutureIntersection and delete sc.DeleteLineUntilFutureIntersection. But, I need to store the handle of these lines and delete when candle body closes not when it intersects with a wick. 2. I don't see a way to store an array with any of the in-built persistent methods. 3. I have written few studies to read subgraph from other studies from another chart. I also see this method sc.GetPersistentSCStringFromChartStudy to read persistent variables from another study. But, I'm figuring out a way to store the line/price array in the persistent storage first to read from another study. Worst case I will store the price array as a delimited string using sc.GetPersistentSCString Any help would be greatly appreciated, Thanks! |

If you know the size of the array that you need, then you can use `sc.[Get|Set]PersistentPointer()` to dynamically allocate the memory for the array. See ACSIL Programming Concepts: Dynamic Memory Allocations Within Study Instance If you need an "array" which grows dynamically, then you can use a vector from the standard C++ library. But memory allocation for classes is different in ACSIL. See ACSIL Programming Concepts: Allocating Memory for Classes |
