Overriding error

[Lejczek]

Hello

First of all, I would like to say that I am an absolute beginner in ninjascript coding...
I am currently in the learning phase and I need a little help with a problem that I don't know how to solve...
I get an error when compiling ninjascript, it is probably an error in the object overriding and I don't know how to solve the problem...

I have defined a range using
private Series<double> MySeries;

next I create an object
MySeries = new Series<double>(this);

then I specify a condition on this object that will hold the difference
close - open of the current candle

MySeries[0] = Close[0] - Open[0];

and I would like to create a something like this
if (
MySeries[0] >2 * StdDev( MySeries[0] )[0]
)

but every time I try to compile the script, I get an error related to overriding..
Once again I apologize for the beginner's question and thank you very much for any help..
I would like to understand at least the basic logic of how to create ninjascript and where I am making a mistake..

Hi Lejczek, thanks for posting. The initialization of MySeries should be:
MySeries = new Series<double>(this, MaximumBarsLookBack.Infinite);

If this does not resolve, please post a screen shot of the code and the compile error and I will have a look at it.

Kind regards,

Have a nice day Chris
Thank you very much for your quick reply
I tried to apply your fix, unfortunately I am getting the same overriding error CS502 CS503..
In attachement I send my simple code..
I would like to understand where the error is, so I can learn something and know how to solve similar problem
Thank You again very much for your time and your help

Hi Lejczek, the StdDev function had invalid arguments. It needs a Series and a Period. Something like this will work:
StdDev(MySeries, 3)[0]

Kind regards,

Thank you very much for your advice !
The code compiles without problems and helped me to understand where the error is..
I would like to ask one more thing..
I would like to get the average range of the certain numbers of bar again using iSeries.
I have again a similar code

private Series<double> MySeries;
MySeries = new Series<double>(this, MaximumBarsLookBack.Infinite);
MySeries[0] = High[0] - Low[0];
if (MySeries[0] > SMA(MySeries, 20)[0])
.....

I am not sure if using SMA() function to get the average value over a few numbers is the most appropriate or there is a better solution ...
Thank you again very much for any help

Hi Lejczek, thanks for the follow up. Using the SMA would be the best method to take an average of a series. The code you posted looks good to me. Make sure to test it out.

Kind regards,
