Hi Trying to pick the highest hi for past 10 bars with a 1 bar offset. This means current bar's value would be highest high of the past 10 bars starting with the bar to the left. I tried creating array "PrevHi" to load high 1 bar back then use gethighest function on it. Can you please tell me my error using this code? The DLL error I am getting is Starting build of Custom Studies Source File: Fx.cpp. -- 11:34:43 "C:\SierraChart\CPPCompiler\bin\g++.exe" "C:\SierraChart\ACS_Source\Fx.cpp" -march=i686 -mtune=i686 -O2 -shared -static -static-libgcc -static-libstdc++ -s -fno-rtti -fno-exceptions -o "C:\SierraChart\Data\Fx.dll" C:\SierraChart\ACS_Source\Fx.cpp: In function 'void scsf_CapPoints(SCStudyInterfaceRef)': C:\SierraChart\ACS_Source\Fx.cpp:42:60: error: invalid initialization of reference of type 'SCFloatArrayRef {aka c_ArrayWrapper<float>&}' from expression of type 'float' SCFloatArrayRef PrevHi = sc.BaseData[SC_HIGH][sc.Index-1 ]; ^ -- End of Build -- 11:34:44 SCSFExport scsf_CapPoints(SCStudyInterfaceRef sc) { if (sc.SetDefaults) { sc.GraphName = "Capitulation Points " ; sc.Subgraph[0].Name = "Cap Points (20D)> "; sc.AutoLoop=1; sc.FreeDLL = 1; return; } SCFloatArrayRef PrevHi = sc.BaseData[SC_HIGH][sc.Index-1 ]; float HighestxBB = sc.GetHighest(PrevHi, 10); 10 barssc.Subgraph[0][sc.Index] =HighestxBB; return; } SCSFExport scsf_CapPoints(SCStudyInterfaceRef sc) { // Section 1 - Set the configuration variables if (sc.SetDefaults) { sc.GraphName = "Capitulation Points " ; sc.Subgraph[0].Name = "Cap Points (20D)> "; sc.AutoLoop=1; sc.FreeDLL = 1; return; } SCFloatArrayRef PrevHi = sc.BaseData[SC_HIGH][sc.Index-1 ]; float HighestxBB = sc.GetHighest(PrevHi, 10); sc.Subgraph[0][sc.Index] =HighestxBB; return; } |

The code you detailed plots the highest high past 10 days BUT does not offset by 1 bar i.e. sc.index-1. The indicator needs to plot the highest high past 10 bars excluding the current bar which is still in process of completing. I tried to change your line by adding an offset and I got errors. Orig> float HighestxBB = sc.GetHighest(sc.BaseData[SC_HIGH], 10); Changed to > float HighestxBB = sc.GetHighest(sc.BaseData[SC_HIGH][sc.Index-1], 10); Error log follows C:\SierraChart\ACS_Source\Fx.cpp: In function 'void scsf_CapPoints(SCStudyInterfaceRef)': C:\SierraChart\ACS_Source\Fx.cpp:47:72: error: no matching function for call to 's_sc::GetHighest(float&, int)' float HighestxBB = sc.GetHighest(sc.BaseData[SC_HIGH][sc.Index-1], 10); ^ C:\SierraChart\ACS_Source\Fx.cpp:47:72: note: candidates are: In file included from C:\SierraChart\ACS_Source\Fx.cpp:2:0: C:\SierraChart\ACS_Source\sierrachart.h:3008:8: note: float s_sc::GetHighest(SCFloatArrayRef, int, int) float GetHighest(SCFloatArrayRef In, int Index, int Length) ^ C:\SierraChart\ACS_Source\sierrachart.h:3008:8: note: candidate expects 3 arguments, 2 provided C:\SierraChart\ACS_Source\sierrachart.h:3025:8: note: float s_sc::GetHighest(SCFloatArrayRef, int) float GetHighest(SCFloatArrayRef In, int Length) ^ C:\SierraChart\ACS_Source\sierrachart.h:3025:8: note: no known conversion for argument 1 from 'float' to 'SCFloatArrayRef {aka c_ArrayWrapper<float>&}' -- End of Build -- 15:39:54 |

We really have limited time with to help with this. We recommend contacting Onn here: https://www.sierrachart.com/index.php?l=doc/SierraChartStudyAndSystemProgrammers.html#ThirdPartyList Also, the easiest way to accomplish an offset is by using the Displacement setting on the Study Subgraph in the Study Settings window for the study.

This is what you want to use: float HighestxBB = sc.GetHighest(sc.BaseData[SC_HIGH],sc.Index-1, 10); Sierra Chart Support - Engineering Level Your definitive source for support.
