Expression As Variable

[JT454]

Is it possible to define a variable with an expression containing Ninja Trader Indicators such as

SMA(10)[0] < SMA(20)[0]

where the expression can now be used as any other variable??

In other words, can I use the above expression as a bool type variable and if so how would the syntax read? Thanks for any input.

You could store it like this and just pass around the variable isLess:

bool isLess = SMA(10)[0] <  SMA(20)[0];

But if you want to re-calculate the expression every time you use the variable you're probably better off putting it in its own method and using the method wherever you want that expression:

bool IsLess() 
{
 return SMA(10)[0] <  SMA(20)[0];
}

Because of precedence of operators, I would add parentheses to avoid ambigious statements. Like this:

bool isLess = (SMA(10)[0] < SMA(20)[0]);

But bool has only two values, true and false, hardly a real variable; so for readibility concerns, the conditional statement would commonly be part of an if statement. Like this:

if ( SMA(10) < SMA(20))
{
// set bool variable to true or false, or do something else
}
