Only show smallest variable

Jagg · #1 (**permalink**) 03-23-2007, 12:17 PM

Hi,

I have three variables (values of this variables are for example: 68, 25, 93). Now I will only show the smallest one of them in the indicator window.

How can I check this three variables so I get back the smallest one?

Thanks

for example: 3 variables are var1,var2 and var3 and additional variable called smallest.

if(var1<var2) smallest=var1;
else smallest=var2;

if (var3<smallest) smallest=var3;

Ok, thought there is a small functionn out there for that....

Say it are five variables... how to it then?

Thanks

I think that is something that is missing from MT4's math routines.

You can use the MathMin(Var1, Var2) in a loop to do this. It sucks to do something complicated for something that simple. I with MT people provide us with a built in Highest and Lowest routine for any number. Currently, it can only do that for the OHLC type of values.

The following snippet can be used for any fixed number of variables:

PHP Code:


			
double values[] = { var1, var2, .., varN };

double min = ArrayMinimum( values );

Ok, I have PDiff, S1Diff, ... variables (double). Now I tried:

PHP Code:


			
double values[] = { PDiff, S1Diff, S2Diff, R1Diff, R2Diff };

double min = ArrayMinimum( values );

but get

Code:

'}' - comma or semicolon expected
