Hello everyone,

I am just getting into programming for multiple data sets. My question is this. When I have a rather complicated indicator to calculate with 2 data sets; Is there a way I can copy my original code (For one data set) and paste it in below, and create a command for the newly pasted code to refer to data 2 only?

I have figured out have to program with 2 data sets for simple things like a moving average, but there must be an easier way to do it for a indicator with lengthy code like this.

Any help would be greatly appreciated.

See the attached code for an example. I would like to plot the results from data sets 1 and 2 on my main price chart.

Thanks in advance for your time and have a great day,

Donovan

Donovan,

one approach could be to turn your code into a function and compute the function on different data streams.
You can find examples on futures.io or in the official forum:

Hello ABCTG,

Thanks so much for taking the time to respond.

As soon as I read your reply, I knew that was exactly the answer I needed. While I currently do not know how to make a function; after doing some research that is certainly something I can learn (And should learn if I want to be a programmer).

Thanks much for the most succinct reply I have ever gotten in a forum!!

Have a great day,

Donovan

Donovan,

thank you for your feedback. If you haven't checked the free EasyLanguage Essentials PDF, yet, I would definitely recommend taking a look at it. It will teach you a lot of the basics.
