New here - Eclipse and Examples provided by MotiveWave

[Khaled]

I installed Eclipse and followed all the steps described in the last section of https://www.motivewave.com/sdk/MotiveWave_SDK_Programming_Guide.pdf but when I tried to Compile the few Studies shared on the website https://www.motivewave.com/sdk/MotiveWave_SDK_Programming_Guide.pdf it showed error messages

" /Users/Khaled/eclipse-workspace/MotWaveMACROSS1/MotiveWave Studies/src/study_examples/ATRChannel.java:3: error: cannot access DataContext
[javac] import com.motivewave.platform.sdk.common.DataContext;
[javac] ^
[javac] bad class file: /Users/Khaled/eclipse-workspace/MotWaveMACROSS1/MotiveWave Studies/lib/mwave_sdk.jar(/com/motivewave/platform/sdk/common/DataContext.class)
[javac] class file has wrong version 63.0, should be 61.0
[javac] Please remove or make sure it appears in the correct subdirectory of the classpath."

As shown on the attached screenshots.

I'm running MotiveWave 6.7.10 and Examples don't show under Study.

How can I overcome this please?

Had the same issue

You'd be better off posting this to an Eclipse, or Java dev forum. You have a mismatch between your Java versions that need to be brought in sync.

Also, if you'd rather start with Intellij Idea, here's a tutorial:

Thank you for this! I was able to play around with this and get it to build with no errors but it did not import any of the example studies in motive wave. Where would I go to make a new study and test it?

I am new to this so sorry if this is a easy thing and I just missed it.

You have to deploy the class files to your /Motivewave Extensions/dev folder. Have you read through the MW SDK guide?

Oops...missed that post . Good work.

You mentioned in that thread that Java has a steep learning curve...true. Unfortunately, the MW SDK also has a steep learning curve

NinjaTrader's NinjaScript and Think or Swim's ThinkScript are powerful scripting languages built on top of their respective SDKs. What takes 3 lines of code in NS/TS can take 10/20/30 or more in MW.

IMHO, MW is the dest-designed charting and trading app I've ever seen--which makes it worth struggling with it's rudimentary SDK. Though something like Sierra Chart probably has the most stable, bulletbroof trading engine, it is butt-ugly--like taking a time machine back to 1993, with a very Windows 3.1-esque interface (in other words--NO interface ), proving that great engineers don't necessarily make even mediocre designers.

It'd be awfully nice if MW devoted some more attention to the SDK--either adding a scripting language, or licensing some commercial software to package with MW (like, say, Trading Indicators Strategy Builder ). It would make novice coders very happy, and make MW a truly complete package.

I am facing the same issue. How to resolve this?

This means the JAVA-version you compile with is either to old, or the MW-SDK.jar too new.

You should select a newer JAVA-version (somewhere in the Eclipse Project Settings), or get your hands on an older MW-SDK.jar
