I was able to find the Building blocks creating this error in Random Groups.

It is the Equals and not equals Blocks .

I attached an example with equal blocks but the not equals blocks will not work with random groups

I have this error :

at SQ.Blocks.Comparisons.IsFalling.OnEvaluateComparison(IsFalling.java:57)


I removed all  Equals and not equals Blocks , And I still have this error 


What does it means ? How can we avoid this error ?

I can't remember all the problems I ran into trying to get groups working but eventually I did. Could it be that you have some members of your group which are not selected in the building blocks tab? Blocks (I think) need to be both selected in the building blocks tab as well as being members of the group. I'd attach the template (the template contains the group data too btw)

Some Building Blocks are producing error. but how do we know which one ?


for example we have only this.IndicatorLeft  without the block  name


We need the block name. We need SQX to not stop for one null block

I tested block by block, I check the XML template. there is no problem inside the template, The group of block is inside it with its parameters. It should work


I did many tests , it is clearly a bug inside SXQ.


I have results to share with the community , I need this features

All of your random conditions are called from groups in this template, so why not just select ALL blocks from the building blocks tab? It looks like you have randomly chosen action as well so don't forget all the order type blocks too. 

I think the only files necessary to reproduce your issue will be the build config file and the template (and any custom indicator snips.) I see the template but did you attach the build config somewhere?

Thank you Bentra for your answer.


Good idea Here is the Build .


Bentra, could you explain more when you write "All of your random conditions are called from groups in this template, so why not just select ALL blocks from the building blocks tab? It looks like you have randomly chosen action as well so don't forget all the order type blocks too. "


In my build , I followed your advice and selected all blocks in the building blocks tab.  


When you write about random action, do you mean the order types/Exit type ? I selected them as well. But I still have this error.


Thank you for your help

I was about to try and reproduce your issue in 136 dev1 but I don't have the custom snippets. Someone will need all the custom snippets, the template, and the build config together to exactly reproduce your situation. I did notice this conflict: The template has SL and TP turned off but you have selected SL and TP in the build config....

Status changed from New to Fixed

I found the problem, there wasn't a proper support for a type of snippet that uses sub blocks, such as IsLowerCount


Fixed in Build 136 Dev2.
