Nesting And Blocks

Mind giving a specific example of what you could accomplish with the your "while" logic that you can not accomplish with chaining "and" conditions? In your example you could just chain with "and", what's the difference? (If bullish AND macd > 0....) 

In programming "while" is to initiate or close a loop but we can't loop the conditions in isolation over and over, we have to continue running all the code.

Any reason this applies to genetic evolution as apposed to the wizard or random gen? 

I wasn't talking about while loops. From what I understood about the and condition, it can only pair blocks together in a chain one by one instead of nesting blocks together. I have never seen SQ look at multiple conditions with an and condition. The format would essentially look like (cond1 && cond2 || condN) && [while] cond3. If SQX already has the ability to nest these blocks together and apply and conditions in this way then please ignore this. I was really only referring to the parenthesis and how conditions can be grouped with an otherwise and statement

When I mean for GE, I mean for parameters able to be selected for GE whether that be in the building blocks or otherwise.

I have since updated the description to make this a little more specific. If SQX already has the ability to do this then please ignore this.

SQ already has this ability, AND and OR blocks are "naturally" nested. Just look at the MQL code and you'll see the quotes.
