MultiCharts: Trading Software for Automated Trading and Backtesting

bluejack

Hi Henry, there was no mail announcement about MC .NET SE yet. Is this intended?

bluejack

Thank you very much for considering my suggestion!! With the price increase in January you lost me to AB but I will take a look at Multicharts.NET SE again and probably return because I really like C# as a programming language and want Multicharts.NET to be a success. I think the community will grow...

Did you try to directly specify Me.effratiolength instead of the new Lambda expressions? I'm guessing from the error message that these length variables should be simple Integers. It seems you have to do this: Me.m_adaptivemovavg1.effratiolength = Me.effratiolength Me.m_adaptivemovavg1.fastavglength...

Works for me in IE 10

To make the ecosystem around MC.NET strongly grow and healthy I think its inevitable to use a similar model like NT. Make a light edition which is free and snaps more and more developers to MC.NET but make any trading capability a premium feature. There could be other premium features like the new V...

I would be happy to see an improved version of the API. Its early enough to do this step. The longer you wait the more must be changed.

bluejack

Threads can also be used with 1.0-3.5 .NET. Only change is that 4.0 makes it easier to parallelize with less code.

bluejack

I suggest if the devs can't reproduce it to send a memory dump to them. They should be able to analyze this. 2GB mem usage is not normal.

bluejack

Latest beta had some fix about memory usage. Try it.

MultiCharts .Net 8.1 is expected this week.

Any news? Is it delayed?

bluejack

I still hope that they would work through more issues reported in the project management. Many valid issues are deferred and ignored forever it seems.

But thanks for the dedication to work on MultiCharts from me too.

bluejack

Should be an easy fix. Or MultiCharts.NET should use .NET 4 which is the best option imo.

bluejack

Is the following strategy possible to write in MC.NET? Everyday a set of 100 stocks is evaluated to a certain value as result (e.g. RSI). These stocks are then ranked/sorted by that value and the strategy should issue buy or sell orders on up to 10 stocks on the list (highest ranked and above a tres...

If you open it from PowerLanguage editor I think the files are generated new everytime.

bluejack

Walter, all default values are specified while constructing the corresponding object. That means there is no need in "Use as default" option for study style. It will be eliminated in one of the future versions of MultiCharts .Net. From a user point of view it would be important that this feature "U...

bluejack

It would wonder me if such a pln file is usable in both versions as that would mean you can develope in .NET with the standard version of MultiCharts. I would for sure welcome such a feature as it brings both worlds together. As for now we are a splitted community.

bluejack

Did you try BarsOfData(x)? I saw it in the help.

bluejack

You can't load 32 bit dll's into 64 bit software. You would need the 64 bit dll.

Perhaps Multicharts has some workaround so theres still some hope.

bluejack

How would this work in regards of NT code?

You can't magically convert NT code to Multicharts as it uses a completely different framework.

bluejack

I use VS2010 + Resharper all the time and have no problems with it. Performance is ok for me and I edited already files with 5k+ line code with it. Far from what we will have here. Just my opinion.

bluejack

Is there a special reason for recommending version 2008, or is it okay to use version 2010 as well?

Where was VS2008 recommended? VS2010 is the way to go.

bluejack

They should release a hotfix for this.

bluejack

There should be a spread ratio indicator if I remember right.

bluejack

This is probably no issue, but just checking so that I don't install 'incompatible' versions: Can a .pln file exported with a 32bit version be imported & compiled in the 64bit version, and vice versa? Yes because its only source code with some meta information. Is there a way to let the MC .NET edi...

bluejack

Please be more precise. Do you mean Virtual Machine by VM? PL code is compiled to a dll. Yes I meant a Virtual Machine. I just wondered how PowerLanguage of the standard MultiCharts edition is compiled. So did I understand right, you create a dll consisting of x86 machine code when compiling PowerL...

bluejack

Really awesome! Very cool. The only drawback it seems if its made as custom draw that its no real object (or plot) in the chart. So you can't click with mouse on it directly to select it and change input parameters. Is it possible to make PlotObjects (like the PPB_MA above) the same way? Fully custo...

bluejack

@Dave:
Is EasyLanguage/PowerLanguage code running in a VM? Is it compiled to byte code or machine code?

bluejack

is it possible to use indicators and strategies compiled in EL as well as .Net in same platform? Also is it possible to call function of one from another language?

No thats not possible. The EL engine is not included in MC.NET. Thats why studies and strategies have to be rewritten into .NET code.

bluejack

I want to mention that in my opinion MC.NET is way more powerful in what users can do with it once they learned the new platform. I see several scenarios which will be impossible to do in standard MultiCharts. Flexibility is the main selling point for MC.NET and will certainly be extended in future ...

bluejack

Works nicely as indicator if its exactly overlayed over the standard barchart. Is there a way to influence the drawing of a bar directly? That would be awesome. In other words is it possible to take full control over drawing a bar or candle? Like drawing candles with gradient colors depending on ind...

bluejack

I appended a solution for the price format here viewtopic.php?f=20&t=10680

Volume formatting can be done easily too in the code.

bluejack

Market Depth on chart 2 is interesting, but it does not recognize the numbers of decimals of the instrument. Which is the line of code to modify ? I fixed it. The problem was that the price format was not considering the price scale of a symbol. (Import the attached .pln File with PowerLanguage Edi...

bluejack

Could you provide an example which shows blue bars if Close > MA and red bars if Close < MA?

bluejack

@rivertrader:
Seems you have to add the reference from inside the PowerLanguage .NET Editor.

Rightclick into script => References...

bluejack

When you are calling EventDraw you can send the DrawContext parameter.

You meant when you use the callback EventDraw you *get* a DrawContext object which in turn can be used to convert pixels to chart space and versa.

bluejack

Please provide mode details. Which library are you trying to use and what does not work exactly?

Please see viewtopic.php?f=19&t=10709 and https://www.multicharts.com/pm/viewissu ... no=MC-1079

bluejack

A ChartPoint is only a structure consisting of Price and Time.

You have to create a new ChartPoint structure and set the price and time fields e.g. with help of the Bars object.

bluejack

The major advantage is now being able to link MC to an incredible amount of 3rd party libraries and software

Yes when we know how to add the dependency as it unfortunately didn't work yet.

bluejack

Another way to initialize the auto property is by setting the value in the constructor.

Code: Select all


public TestStrategy(object _ctx):base(_ctx)

{

	AtrLength = 10;

}



[Input]

public int AtrLength { get; set; }

Lambda is used to supply a function for a data point in the series. In this case its a simple function which always returns the "length"-number for every point in the length data series. When the code runs through the average series it will call your "return length;" function for every point and req...

bluejack

There is one subtlety with properties. Properties are public accessor methods; as such they are much slower than direct variable access. So.. if you are going to be accessing the property internally in your class, it is better to use the verbose version and access the private members (for simple ac...

Since I didn't find the appropriate section in the project management for MultiCharts.NET I will report that bug here.

When I draw a trendline it draws multiple lines at once. When I release the mousebutton these lines disappear.

See attached screenshot.
