In the blog post introducing the feature you can see orders that were sent to VisualChart over the COM interface.
To take into account:
Test a lot. The code may contain bugs, your code may contain bugs and even VisualChart may contain bugs.
You need the python comtypes packaged detailed in the documentation. The Pull-Request hasn't yet been integrated into the main development tree (which seems more or less stopped from a development point of view)
I'm sorry, but I can't not say it: Renko charts look adorable. The little bricks going up and down are just... so freakin' cute. I wouldn't mind hanging these things up on my wall or storing them in little books or making a quilt out of them.
Now that that's out of the way, I'm guessing that the Renko filter could be used as a data feed to build strategies so you can do backtests or compute statistics.
My humble apologies for how this issue has been approached.
If I ever have a bug report in the future I will be sure to include that information.
As it turns out, you are quite right... I stuffed up on the version front and wasn't using the lastest. I have since upgraded and the script runs completely! Wish I knew this yesterday before wasting several hours trying to debug a problem which didnt exist (my mistake!)!!
I assure you I haven't abandoned the getvalue thread, I am still working on addressing your suggested solutions and will get back to you to confirm if I have resolved the issue regarding short positions as soon as I have time to do some more thorough testing.
As a suggestion, with those example codes, would it be possible to include all elements for users such as myself to do a full run without edits? Perhaps inclusion of the necessary files etc too would be valuable and save some time. I spent some time yesterday to try and get your blog post to run and didn't consider that I would have to incorporate additional code to re-order data etc. I understand that it would never have worked for me though given my version issues..! But this may be useful for others going forward.
Thank you for your time and patience in assisting me as I learn this platform and process.
