Plot using RoundedToTickSize in non primary BarsArray - question

[sandman]

I am using the following code snippet in a multi time frame indicator:

Neutral.Set(EMA(BarsArray[9],20)[0]);

It works with no problem and properly shows me a price marker on the right side.

Now I am trying to "convert" this to use RoundedToSickSize. In other indicators I used to use this, and it worked:

Neutral.Set(Instrument.MasterInstrument.Round2Tick Size(EMA(20)[0]));

However, when I am now trying the following to access the BarsArray[9]:

Neutral.Set(Instrument.MasterInstrument.Round2Tick Size(EMA(BarsArray[9],20))[0]);

I get an error message as it does not want to accept the code, "... has some invalid arguments".

Any idea what I need to do differently here?

Hello sandman,

Thanks for your post.

If the Neutral.Set() code is copied verbatim, you have an extra end parenthesis after the EMA and before its BarsAgo reference. I have a video demonstration testing Round2TickSize with an EMA on a secondary series and I am not seeing any issue. Demo and test script attached.

Please let me know if there is anything else we can do to help.

Jim. Thank you very much for your very comprehensive response incl the video. You are right: it was that extra parenthesis.
