Works for me in replay and I assume live too. Not on historical loading as the calculations are independent on loading.

Thx @Trembling Hand for had a look on my question but on your pic the RSI value of the left chart is different from the value shown in the message log window. My aim is to get the correct value for further calculations.

If it matters... I'd like to use this on the same instrument but different time frames. To evaluate higher time frame's values for lower time frame's dicision. The study I need the values from contains 3 subgraphs and of course sooner or later I'll need all of them

As you can see I try to get (only now other way around) the value of RSI from the 30sec chart. The study still runs on chart#4. The price graph value window' value differs from the message log.

I found a solution for this in the Studies2.cpp

Hey @1m1k3,
I need the same thing.
Can you guide me how to get the index of an event occurring?

Where exactly is the solution in studies2.cpp?

Thanks.

In the study called BarNumbering there are a few lines which do the counting of bars. You just have to amend here and there to fit into your study.

The code for most of SC studies and trading systems are in C:\SierraChart\ACS_Source in .cpp files

That study is in Studies2.cpp around line 3757

I have been looking around through threads on here, and Sierra, trying to get a start on building a little automated setup, so I can backtest without a pen and paper. I haven't really seen anything like what I'm looking for. Most people are asking for what seems to be more data collection/combining studies, and things that are more complex. I think it is rather simple, I just need pointed in the right direction. Not sure if the spreadsheets or ACSIL are what I'm after. Entrance based on a figure given by an indicator: enter long when cross from above, enter short when cross from below. 3 contracts, limit. -7 stop all. Once it comes 4 ticks in favour, stop moves to -4. Target 1, +10 ticks, once hit, stop moves to break even. Target 2, +17. Once target 2 hit, the stop for the final contract becomes trailing at -6. I am not afraid to spend some time trying to code this, in fact I would love to be able to say I put it together somewhat. But I need a template.. if anyone has seen something similar, please let me know.

Hi
In C:\SierraChart\ACS_Source folder there is a .cpp called TradingSystem.cpp and in that file around line 1494 there is already a coded trading system based on crossovers called "Trading System - Study Subgraph Crossover". You can use that as the base code.

Hi everyone,

How is it possible that the loading time of the code on the

https://www.sierrachart.com/index.php?page=doc%2FACSILRefOtherTimeFrames.php&fbclid=IwAR2YD8AcZbYNvA2n6JLxZ-fLNI0cGtican4tj5FZFH6flR0D5DQwLWjXxXM page

is multiple of the Study/Price Overlay study. However they both do the same.

I wanted to build in that code into my study but with this attribute I have better to discard this idea.
Or is there a way to make it quicker?

Thx

The Study/Price Overlay Study is coded directly in C++, and the source code is not available. It appears using an ASCIL version of what is a similar function uses more CPU time.

Please post any questions and problems or suggestions you have in this thread about my Sierra Chart ACSIL for Beginners to keep that thread reasonably concise and clean of tangents. Thanks.

Hi everyone,
I am trying to write a custom function for some calculations but I need to input an array(scFloatArray) into the function.
Now the compiler is showing an error when I call this function and give this array as input. It seems that scArrays are different than normal arrays and hence this error.

Here is the function that I wrote:

 

Code

int barsSinceCross(float arr[], int occurence) { int bars = 0; int reps = 0; for (int i = sizeof(arr) - 1; i > 0; i--) { if (arr[i] == 0.0) { bars++; } else if (reps < occurence) { reps++; } else { break; } } return bars; }

This is where my array is declared:

 

Code

SCFloatArrayRef Array_CrossUp = sc.Subgraph[4].Arrays[4];

And here is the call to the function:

 

Code

barsSinceCrossUp = barsSinceCross(Array_CrossUp, 1);

The error shown by compiler:

Quoting 

no suitable conversion function from "c_ArrayWrapper<float>" to "float*" exists

Thanks.

The compiler is telling you whats wrong. Your function takes a C++ array but you are passing in a SCFloatArrayRef data structure. Change your function parameters to match what you are passing to it like,

 

Code

int barsSinceCross(SCFloatArrayRef arr, int occurence) { int bars = 0; int reps = 0; for (int i = sizeof(arr) - 1; i > 0; i--) { if (arr[i] == 0.0) { bars++; } else if (reps < occurence) { reps++; } else { break; } } return bars; }

EDIT oh but then you cannot index a SCFloatArrayRef like a C++ array so you will have to change the function to use SC methods by pass in the sc reference.
