Hello, 

The Security Data function can call a data array for a particular instrument. A simple example would be:

Cum(Security("Online:ESM9",V) + Security("Online:ESU9",V))

Hello Sir I want to make cumulative open interset indicator by the sum first month,second month and third,month future open interest Sir, I know that the security function will be used but how will it happen And if the security function is not used, how will we do it? and my symbols are coming like this  and (my symbols are in local disk d )

 NSE50 1 - MONTH

NSE50 2 - MONTH 

NSE50 3 - MONTH

Sir, I did not understand how i don't have the latest version is metstock And what do I have to do like this 

Security("Online:Cc1",OI) + Security("Online:Cc2",OI) + Security("Online: Cc3",OI) 

What will be done by doing this? And here's what the online function means

The data path where the data is And what does Cc1 mean here

Hello again,

It sounds like this is really more a case of getting MetaStock to read your data, because until that can be done, forming indicators is of secondary concern.

What file format are your data files stored in? The security function will not work with CSV/TXT so the data must be in a MetaStock formatted data file. If you have CSV/TXT data you can use the DownLoader to Convert this data to the MSLocal (or Legacy) format, which can then be used in the Security function.

The data must be formatted correctly, however in order to be successfully converted.
