You need to check the processing of the study and make sure it is efficient when processing the time and sales data. Can clearly it is taking too much CPU time and not efficient. You need to minimize the number of time and sales records getting processed at once. Sierra Chart Support - Engineering Level Your definitive source for support. Other responses are from users.

Thanks for advice is it related to this? // Zero elements from the first index that was written to last time, to the
// first index that was written to this time. for (int SubgraphIndex = 0; SubgraphIndex < sc.NumberOfArrays; ++SubgraphIndex) { for (int DataIndex = EarliestIndex; DataIndex < OutputArrayIndex; ++DataIndex) sc.Subgraph[SubgraphIndex][DataIndex] = 0.0f; } // Store the last index that was written to EarliestIndex = OutputArrayIndex; if you allow me, I will send you a private message with the complete code Date Time Of Last Edit: 2021-09-15 20:01:02
