Simple Question About Adaptrade Editor

[furytrader]

I am working to code a simple system using the Adaptrade Editor, but I'm being shown an error message that I don't quite understand. 

I have defined:

Var1 = [LHS] Highest(High,20)

Var2 = [LHS] Lowest(Low,20)

Var3 = [LHS] Var1 [Operator]+ [RHS]Var2

However, when I check for errors for Var3, I get the error: 

"Return Type of left-hand side (Price Value) doesn't math operator input type (undefined)"

The operator is set as the plus sign.  Is there something else I need to set?

Thanks,

Mike

The “plus” operator is not valid for adding two prices together because the result would be a “double price”, which is not defined. You can subtract two prices (for a “price difference”), or you  can use add a price to a price difference, which produces another price, but adding two prices is not defined.

Thanks Mike. 

In my case, I'm trying to find the average of the highest high price over 20 bars and the lowest low bar over the past 20 bars.

Is there some other way to calculate this using the Editor?  Normally, I would do something like:

(Highest(High,20) + Lowest(Low,20)) / 2

But it sounds like adding prices is not supported and neither is division. 

Thanks again.

That’s an indicator. You would need to use a custom indicator. While you can’t directly add custom indicator through the editor, if you have them in Builder and edit the Builder code, the editor will use them. So your workaround would be add it as a custom indicator in Builder, build a small population, and edit one of the strategies containing the indicator in the editor.
