This answer sums it all : )
Thank you once again

Thank you @jstap for your alternative solution and yes, I can do that the way you suggested. However it'll lead me to create a lot of unnecessary extra blocks.
Since the designer let's us to right-click on the area to pick a variable, I thought it was doable:

Hello everyone,

Can I use operators like >,<,>=,<= as variables and use them in Condition blocks like in here?
I tried creating string variables but whenever I pick a variable on the highlighted operator area and press "Update", the block reverts that change.

Any help would be highly appreciated.

@jstap Thank you very much for the quick response. At least an online index is needed for Custom Blocks which lists those reserved keywords like:
~next~
~inext~
~datatype
etc.

or some explanation about:
using variables
referencing functions
output functionality
etc.

I believe Studio is can be a very handy tool but then again too little info about how to properly use it. I'll head back to my original post now.

I'd appreciate very much if someone can show us how to create a "condition" block that already exists in fxDreema as a Custom Block with the exact same parameters and functionality.

@l-andorrà Once I get the grasp of the basics, I'm quite certain that I can build many Custom Blocks.

off topic: I'm aware of your videos on fxDreema and the services you provide for quite some time. I really appreciate your work.
It's a pleasure for me to see your response in my post.

Hello Everyone,

As a long-term mql coder, I have quite an experience coding in MT platfrom and I find fxdreema extremely useful.

In my opinion, Custom Blocks could be very helpful for people like me. However there's a very limited know-how and examples about it (I Googled a lot and also reviewed relevant topics in this forum)

I'd like to start with a very basic question and maybe we can proceed from here.
Let's say I'd like to create the exact "condition" block as a custom block with the same parameters and functionality. Could somebody please show me how to do it?

Thanks in advance,
