How to recall a function into an indicator

[Sam7768]

Hi,

I am trying to write a small indicator that gives a dot when MAs cross. While I can recall SMA or EMA into the code, I am not able to recall say Hull MA.

For example, this below code works

return(ema(50) - sma(5));

But the below code giving out error...

return (HullMA(50)-sma(5a));

I understood that system should store these somewhere and that HullMA is not stored in the system.

What is the solution?

HullMA() is not an existing function like sma() or ema().
You will need to create that function within your script at which point you can call it either directly or using the efsInternal() function or if you have an efs that already calculates the Hull Moving Average you can call that using the efsExternal() function.
For the description, syntax and examples on these functions see the links to the corresponding articles in the EFS KnowledgeBase. See also this and this thread in the forum for more detailed examples on the use of these functions. If you search the forums you will find many other examples of this functionality as the topic has been covered at length many times before
