Here they are as there are few 3rd party examples
BIG UPDATE BELOW which means I got this partially working!!
I tested to add a Redis NOSQL (3rd party) using simple Jedis Jar. This was done fairly easily with another Mac OS based proprietary platform like Dukascopy JForex. I could see the Redis update when running the strategy or study within MotiveWave. This builds fine. but there does not seem debugging log capabilities for a strategy but there is for studies. Also, when making changes in the Java in Eclipse, the MotiveWave platform does not seem to pick up the latest changes in a dynamically changed class. The only way for this to be picked up is by reseting the platform.
My opinion but it is looking good but …
I think there needs to a be lot more samples from MotiveWave instead of just 3 simple studies and 1 strategy. I could only find one other 3rd party providing further examples. Unfortunately, I am not in the business of spinning my wheels to figure this out as compared to other brokers/platform who provide flawless coding experiences. I think I need to see a demo or better examples.
Until then, I am may just use MotiveWave for charting or connecting with IQFeed only. I can do that with the entry level MotionWave edition. This platform is very exciting indeed but I need to get to see improvements in the above area before I get serious with it from a coding point for view.
BIG UPDATE on getting Java coding! (Nov 29)
See the video to see what is working including text writing and CSV reading files
Here is working Java code as hinted in the video
