Error CS0021

[sub5mango]

Hi

I am trying to do a SMA on a CCI with the periods used as an input. This code is being kicked out with a CS0021, Cannot apply indexing with [] to an expression of type 'method group' for line 46.

I have looked the error message up but it doesn't seem to help with line 46: for (int barsAgo = 0; barsAgo < Period; barsAgo++)

also i put brackets after CCI(0) - should there be a number instead of 0 - what is it? where do i find it from?

sum = sum + CCI(0)[barsAgo];

thanks

protectedoverridevoid OnBarUpdate()
{
if (CurrentBar < Period) return;


double sum = 0;
for (int barsAgo = 0; barsAgo < Period; barsAgo++)
{
sum = sum + CCI(0)[barsAgo];
}

Plot0.Set(sum/Period);


}

Clicking on the error message brings you to the erroneous code line which you then can fix.

Also: "SMA(CCI(<yourCCIPeriodValue>), <yourSMAPeriodValue>)" probably is what you are looking for.

To use CCI please see this link: http://www.ninjatrader-support.com/HelpGuideV6/CCI.html

You can put it whatever values you want for the parameters.

Hi there

thanks for the replies - i got it compiled - it was another window i had open that i thought i'd cancelled.

my first attempt at making an indicator.

anyhow, now it's working it's not what i wanted.

can you point me the direction of info i can use to build this:

if CCI value for the last six periods is all positive OR all negative, sum them and then divide by 6.

i will then apply that factor to a parameter in a strategy to give an indication of trend strength.

(if you know of a really good, simple measure that will do the same i would love to know about it - so far I have tried ADX, Aroon and DM aren't working for me)

thanks

Sure just go CCI(20)[0] > 0 && CCI(20)[1] > 0 && CCI...etc etc inside an if statement. Then add them up and divide by six. Or you can use a loop. Whatever works for you.

cheers josh

I have writen this code but nothing appears on the indicator when i add it to a chart,
so i added print statements,
but I can't get anything on the output window

so simple one, how do I "run" the code to create values to appear on the output window? (and is this code right...while your on!)

is there a detailed manual/bible in one place which covers the prog language?

double sum = 2;

if (CCI(14)[0] > 0 && CCI(14)[1]);
sum = CCI(14)[0] + CCI(14)[1];

Print ("pos sum " + sum + " CCI " + CCI(14)[0]);

if (CCI(14)[0] < 0 && CCI(14)[1]);
sum = CCI(14)[0] + CCI(14)[1];

Print ("pos sum " + sum + " CCI " + CCI(14)[0]);

TF.Set(sum/2);
}

Thanks.

ok, so i added this statement

if (CurrentBar < 2) return;

2 because i tried it with 1 and it didn't work so i have 2 periods so i tried 2.
