Hello. I am a little confused about the use of scfloatarrayref vs. scFloatArray. I created identical studies below-the top one uses scfloatarrayref, the other just scfloatarray. They yield difference results. Can someone please explain the difference and when one should use 1 over the other? THANKS. SCSFExport scsf_Sigma3(SCStudyInterfaceRef sc) { if (sc.SetDefaults) { sc.AutoLoop=1; sc.GraphName = "SigmawArrayRef" ; sc.Subgraph[0].Name = "Spike3 "; sc.AutoLoop=1; sc.FreeDLL = 1; return; } SCFloatArrayRef Close1BB = sc.Subgraph[0].Arrays[0]; SCFloatArrayRef Close2BB = sc.Subgraph[0].Arrays[1]; SCFloatArrayRef Cl2ClLog = sc.Subgraph[0].Arrays[2]; SCFloatArrayRef Sigma = sc.Subgraph[0].Arrays[3]; SCFloatArrayRef DollarSigma = sc.Subgraph[0].Arrays[4]; SCFloatArrayRef Delta = sc.Subgraph[0].Arrays[5]; SCFloatArrayRef Spike1BB = sc.Subgraph[0].Arrays[6]; Close1BB[sc.Index] =sc.Close[sc.Index-1]; Close2BB[sc.Index] =sc.Close[sc.Index-2]; Delta[sc.Index] = Close1BB[sc.Index]-Close2BB[sc.Index]; Cl2ClLog[sc.Index] = log(Close1BB[sc.Index] / Close2BB[sc.Index]); sc.StdDeviation(Cl2ClLog,Sigma,480); DollarSigma[sc.Index] = Sigma[sc.Index] * Close1BB[sc.Index]; Spike1BB[sc.Index]=Delta[sc.Index] / DollarSigma[sc.Index]; sc.Subgraph[0][sc.Index] =Spike1BB[sc.Index]; return; } SCSFExport scsf_Sigma4(SCStudyInterfaceRef sc) { // Section 1 - Set the configuration variables if (sc.SetDefaults) { sc.AutoLoop=1; sc.GraphName = "Sigma4 " ; sc.Subgraph[0].Name = "Spike in Sigmas "; sc.AutoLoop=1; sc.FreeDLL = 1; return; } SCFloatArray Close1BB ; SCFloatArray Close2BB ; SCFloatArray Cl2ClLog ; SCFloatArray Sigma; SCFloatArray DollarSigma ; SCFloatArray Delta; SCFloatArray Spike1BB ; Close1BB[sc.Index] =sc.Close[sc.Index-1]; Close2BB[sc.Index] =sc.Close[sc.Index-2]; Delta[sc.Index] = Close1BB[sc.Index]-Close2BB[sc.Index]; Cl2ClLog[sc.Index] = log(Close1BB[sc.Index] / Close2BB[sc.Index]); sc.StdDeviation(Cl2ClLog,Sigma,480); DollarSigma[sc.Index] = Sigma[sc.Index] * Close1BB[sc.Index]; Spike1BB[sc.Index]=Delta[sc.Index] / DollarSigma[sc.Index]; sc.Subgraph[0][sc.Index] =Spike1BB[sc.Index]; return; } |

This is the correct usage: SCFloatArrayRef Close1BB = sc.Subgraph[0].Arrays[0]; When you want to make a reference to an existing array you need to use SCFloatArrayRef. If you rely upon all of the examples and information in the documentation, you will be fine. The documentation does specify the proper types to use in each case.
