Title: Re: [amibroker] A shorter syntax to reference past elements of array

Herman,

 

You are right that it maight be confusing, therefore I was thinking about using this short form only to reference past

(as it is most common scenario, considering the fact that we all the time attempt *not* to look into the future).

 

The whole story is just to make common expressions like C - Ref( C, -1 ) shorter, like this:  C - C(1)

but I have second thoughts as well, as it truly may create lots of confusion.

Best regards,

Sorry , but imo the new forms are critic and counter intuitive.

C(5) looks back 5 bars.... what would looking forward look like? C(-5)? 

imo, very confusing. I can't help but wonder what made this idea surface :-))
