Hello, Can anyone out there tell me about the performance gains after upgrading to the 64 bit version of SC? Thx, WT |

Hello, On an unrelated topic I noticed you longer have the following documented: sc.GetStudyPersistentVariablesFromChartUsingID(Chart.GetChartNumber(),Chart.GetStudyID()) Is there a more efficient way to pass messages between two charts? I am rewriting some studies for effeincy. What would be the most efficient way to send data to a study on another chart? I plan on staying with sc.GetStudyPersistentVariablesFromChartUsingID but do you have anything better? The Overlay studies could be used buy I only need data from the current bar sc.Index, and I do have other datat that is no not in any study. sc.GetStudyPersistentVariablesFromChartUsingID does cause a lot of recaculations and I'm trying to cut that down. Does the overlay study cause less recaculations? Thx, WT |

Yes that will be supported for the foreseeable future.

Hello, Is anyone looking into this? I went ahead and took the time to switched seven studies to use sc.GetStudyPersistentFloatFromChar()t now all is does is return zero values. Should I open a new thread? It will take me over an hour or two to switch things back and recompile. Could test it on the live GainCapital feed but want to make sure everything works before I turn off my old 1209 version of SC. Thx, WT |

We did not believe there was any problem with these functions and we verified there is not. Here is an example: SCSFExport scsf_GetStudyPersistentVariableFromChartExample(SCStudyInterfaceRef sc)
{ SCInputRef ChartStudyReference = sc.Input[0]; if (sc.SetDefaults) { // Set the configuration and defaults sc.GraphName = "Get Study Persistent Variable from Chart Example"; sc.AutoLoop = 1; sc.FreeDLL = 0; ChartStudyReference.Name = "Chart Study Reference"; ChartStudyReference.SetChartStudyValues(1, 0); return; } //Set persistent float variable with a value of 100 using integer key 1. float& r_PersistentFloat = sc.GetPersistentFloat(1); r_PersistentFloat = 100; // Get a reference to a persistent variable with key value 1 in the chart // and study specified by the "Chart Study Reference" input. Assuming the // "Chart Study Reference" input is referencing this particular chart and // study instance, then this function will return 100. const float PersistentValue = sc.GetStudyPersistentFloatFromChartStudy(ChartStudyReference.GetChartNumber(), ChartStudyReference.GetStudyID(), 1); if (sc.Index == sc.ArraySize - 1) { SCString OutputText; OutputText.Format("%f", PersistentValue); sc.AddMessageToLog(OutputText, 0); } } Sierra Chart Support - Engineering Level Your definitive source for support.

Hello, I have reverted back to how the old function and everything is working fine. It is time for me to move on. Please keep sc.GetStudyPersistentVariablesFromChartUsingID available even if it is not documented. const s_PersistentVariables * p_DeltaLadderPersistVars = sc.GetStudyPersistentVariablesFromChartUsingID(VisibleBarsChart.GetChartNumber(), VisibleBarsChart.GetStudyID()); //ChartStudyInput.GetStudyID() Delta Ladder
if (p_DeltaLadderPersistVars) { TickHigh = p_DeltaLadderPersistVars->f1; //const float& TickHigh = sc.GetStudyPersistentFloatFromChart(VisibleBarsChart.GetChartNumber(), VisibleBarsChart.GetStudyID(), 1); //TickHigh = p_DeltaLadderPersistVars->f1; TickLow = p_DeltaLadderPersistVars->f2; //const float& TickLow = sc.GetStudyPersistentFloatFromChart(VisibleBarsChart.GetChartNumber(), VisibleBarsChart.GetStudyID(), 2); //TickLow = p_DeltaLadderPersistVars->f2; TickValueCurrent = p_DeltaLadderPersistVars->f3; //const float& TickValueCurrent = sc.GetStudyPersistentFloatFromChart(VisibleBarsChart.GetChartNumber(), VisibleBarsChart.GetStudyID(), 3); //TickValueCurrent = p_DeltaLadderPersistVars->f3; //float& RemotePriceCurrent = GetStudyPersistentFloatFromChart(VisibleBarsChart.GetChartNumber(), VisibleBarsChart.GetStudyID(), 4); //RemotePriceCurrent=p_DeltaLadderPersistVars->f4; TickIndex = p_DeltaLadderPersistVars->i1; //const int& TickIndex = sc.GetStudyPersistentIntFromChart(VisibleBarsChart.GetChartNumber(), VisibleBarsChart.GetStudyID(), 1); //TickIndex = p_DeltaLadderPersistVars->i1; //will be replaced with sc.Index //for SimTickPriceMarker ValueHighPrice = p_DeltaLadderPersistVars->f4; //const float& ValueHighPrice = sc.GetStudyPersistentFloatFromChart(VisibleBarsChart.GetChartNumber(), VisibleBarsChart.GetStudyID(), 4); ValueLowPrice = p_DeltaLadderPersistVars->f5; //const float& ValueLowPrice = sc.GetStudyPersistentFloatFromChart(VisibleBarsChart.GetChartNumber(), VisibleBarsChart.GetStudyID(), 5); ValuePOC = p_DeltaLadderPersistVars->f8; //const float & ValuePOC = sc.GetStudyPersistentFloatFromChart(VisibleBarsChart.GetChartNumber(), VisibleBarsChart.GetStudyID(), 6); CurrentOpen = p_DeltaLadderPersistVars->f7; //const float& CurrentOpen = sc.GetStudyPersistentFloatFromChart(VisibleBarsChart.GetChartNumber(), VisibleBarsChart.GetStudyID(), 7); } const float PersistentValue = sc.GetStudyPersistentFloatFromChartStudy(ChartStudyReference.GetChartNumber(), ChartStudyReference.GetStudyID(), 1);
The code you just posted could NOT possibly compile. The function in question has a return type of a reference to a float – float & - not a return type of float. I included a screen shot of my Visual Studio showing the return type of the function. Anyway, looks like I am the only one using this advanced feature since it has been years since this function was developed but no one complained. The thing is if someone else who is new to SC tries the function, instead of posting a message on support, they will just move on to something else. SC is on the cutting edge of trading software, making things like bid/ask data availably 10 years before other popular trading software (Ninja). The new version is very fast and responsive. Keep up the good work. Thx, WT |

I included a screen shot of my Visual Studio Yes it does compile and the reference does not have to be placed into a reference. A copy is just fine. There was no need for a reference in the example.showing the return type of the function. The thing is if someone else who is new to SC tries the function, instead of posting a message on support, they will just move on to something else. Attached is a test chart book demonstrating this. In chart #1, go to Chart >> Recalculate and after you do that look at the Message Log. You will see Chart #2 automatically calculate and display the value of the persistent variable each time. In the next release the example has been updated to use sc.UpdateAlways and increment the persistent variable. Sierra Chart Support - Engineering Level Your definitive source for support.

One other small detail, this name: sc.GetStudyPersistentFloatFromChartStudy Is the functions new name but the old name still works. But in an older version of Sierra Chart you have to use the old name which does not include Study at the end. Sierra Chart Support - Engineering Level Your definitive source for support.

Hello, Here are my screen shots before and after following your directions. Using v1705 It does recalculate but there is no output. Thx, --WT |

It is possible that the particular test functions we used might have been renamed in the latest version and are not going to work in the version you are running. Although we do not see any evidence of that in the Message Log unless it were cleared. Update to the latest prerelease and test again. However, still the ACSIL (sc.) functions being used for getting persistent variables from another chart and study, internally have not changed and have always worked properly.

Yes both of them are included in each installation. There are icons for each of them on the desktop and you can also run the executables directly from the installation folder. The 64-bit version ends with "_64". Sierra Chart Support - Engineering Level Your definitive source for support. Other responses are from users. Try to keep your questions brief and to the point.

Hello, Can you post the code for the example? Still getting zeros with sc.GetStudyPersistentFloatFromChartStudy. Should I replace sc.PersistVars? const float TickHigh = sc.GetStudyPersistentFloatFromChartStudy(VisibleBarsChart.GetChartNumber(), VisibleBarsChart.GetStudyID(), 1);
Source: float& TickHigh = sc.PersistVars->f1;
float& TickLow = sc.PersistVars->f2; //float& PriceForTickCandle=sc.PersistVars->f3; float& PriceForTickCandleCurrent = sc.PersistVars->f3; int& TickIndex = sc.PersistVars->i1; float& ValueHigh = sc.PersistVars->f4; float& ValueLow = sc.PersistVars->f5; float& ValuePOC = sc.PersistVars->f6; float& CurrentOpen = sc.PersistVars->f7; if (CandleType.GetIndex() == 1) { Thx, WT |
