Zheka,

This is the keyword from the TSKIT.DLL library. PLKIT is not used. In PowerLanguage it is required just for compatibility of TS scripts.
So you might want to check more info about it in third party resources.

Hi Polly,

2. EL Extension SDK manual doesn't have any reference to ArrayStartAddr (though it supposedly should)

So, what does ArrayStartAddr do and how should one use it?

Polly MultiCharts

Hello Zheka,

It is not possible to achieve without using dll.
For more detailed info please see this guide.

Also worth looking at Pytorch as well as TensorFlow. They each have their pros and cons, depending on what you want to do. People have used Pytorch with a variety of trading platforms, including MC.

Basically there's a solution for both MC Powrlanguage and MC.net
With MC PL you need to be a bit familiar with C++ to call Python
With MC.net you need to be familiar with C# and be ok with slightly slower runtimes

amw_775

Before I was using Powrlanguage a lot for all my strategies so the fastest way to call Python functions was to create a C++ DLL which opens a Python Interpretor and keeps the interpreter Open. MC sends Python functions to the Interpretor and returns the output back to MC. I am using ...

HellGhostEvocatorX

Do you use tensorflows for multicharts.net and if so, for what? And in general, why did you do this, C# is already pretty powerful. Did you need any special Python libraries?

In complex cases, MaxBarsBack set to Auto-Detect can cause errors, as MultiCharts cannot know what your dll does. You can add in your EasyLanguage script an explicit reference to the earliest bar, for example:

Hi Henry. They already have two APIs, REST trading and streaming based. Please see https://labs.ig.com/
I've already written a crude REST based order interface using Python and a DLL stub almost a year ago. I'm sure your programmers can quickly develop complete IG Markets integration for MC.

Zheka

It probably has to do with wrong parameter type declaration in DefineDLL: passing an array(of doubles) requires a *pointer-to-double*, not just Double. Try declaring it as LPDouble, and try finding an EasyLanguage Extention SDK referenced here: https://www.multicharts.com/trading-software/index.php/...

OK so: it seems that if IOData.DLL finds a line that is more than 254 characters long in the file, it will not look at that line or any other files below that line.
