[sniper]

Hi,

please, I need to a sum of values only if they are positive.
For example : X = a+b+c were a, b,c are positive. If negaive no.

Have someone idea about formula in NT7,

Thanks in advance.

Hello Sniper,

Thank you for your note.

What you could do is add an if statement which checks to see if a, b, and c are positive and if so, set the value of x equal to a+b+c.

Under initialize(),

X = 0;

Under OnBarUpdate you would add,

if (CurrentBar < 1) return;

if(a>0 && b>0 && c>0)
{
X = a+b+c;
}

Please let us know if you need further assistance.

I badly explained myself... in market action a, b and c can be +1 or -1 , i don't know which one is posive or negative.
I can compile a little script like this :
x=0
if a>0
then x=x+1
if b>0
then x=x+1
etc.. etc...
but it looks a dirty code. Is there a single command to do this ?
Best regard .

Hello Sniper,

If you only want to have 1 added to x if either a, b, or c had a positive value you could do,

If(a>0 || b>0 || c>0)
{
X+=1;
}

However if you wanted to add 1 to x each time either a, b or c was positive than you would want to keep them as independent if statements as in your previous message.

Please let us know if you need further assistance.
