Hi everyone

I was trying to code a new indicator and I started by one I'd downloaded from somewhere or other a long time ago...

It contains the following code - the syntax is something I'm not really familiar with - can anyone explain what this code does?


lasthi = hi[0] = useHiLo ? High[0] : Input[0];

I've never used questionmark in my code before and I'm not entirely sure what the colon is doing either!

Thanks.

The expression replaces if ..... then ....else. The meaning is

 

Code

if(useHiLo) lasthi = hi[0] = High[0] else lasthi = hi[0] = Input[0];

The code executed when the expression "useHiLo" is true follows the question mark, the code that is executed when the expression "useHiLo" is false follows the colon.

You can look it up in the C# online reference.
