Cannot apply indexing with [] to an expression of type double

[Gecko78]

Hi,

I'm trying to convert some NT7 codes to NT8 codes. Kindly pardon my limited knowledge in programming.

I've these codes which i convert to NT8, but it returns with the error as per the heading. Any kind soul could advise what is the correct code structure I should use?

NT7
Somewhere down i have this:
RT.Set(4, RLL);

and further down the code, i have this:
[XmlIgnore]
[Browsable(false)]
public DataSeries RT
{
get
{
return base.Values[0];
}
}

NT8
This is what i tried to change to:
RT[0][4] = RLL;

and further down the code, i have this:
[XmlIgnore]
[Browsable(false)]
public Series<double> RT
{
get
{
return base.Values[0];
}
}

Thanks!

Hello Geck78,
Thanks for your post and welcome to the NinjaTrader forum.

I expect the issue is:

RT[0][4] = RLL;

and that changing it to this will compile fine:

RT[0] = RLL;

What do the two inputs mean for the the RT indicator in NT7?

Hi Josh,

thanks for the reply.

i believe that RT was DataSeries.Set(int barsAgo, double value), so i think the value of 4 should still appear somewhere??

Also, sorry, i had actually changed in NT8 version the following:

[XmlIgnore]
[Browsable(false)]
public Series<double> RT
{
get
{
return base.Values[0][0];
}
}

Thanks!

Gecko78,

If the barsAgo value is 4, you would use that instead of 0.

RT[4] = RLL;

Not sure why you would want to do this, but I believe that's how it would be done. I suggest making this change and seeing if the results are the same as in NT7.
