The values are the returns of the indicator so if the last line of the indicator is:

return a,b,c,d,e

then value1 = a, value2 = b value3 = c etc

The parameters in brackets are the variables that the indicator needs. So for example an RSI indicator that just needs to know the period that it should be calculated on would just need one parameter. 14 for RSI[14] or 2 for RSI[2] for example.

The parameters are the adjustable variables that you would find in the indicator settings window in the order they are presented there.

If there are only 3 values and 5 parameters (none of them is zero), then the logic is that the first value always get the firs parameter?

I’m not sure that I understand what you are asking.

An indicator might have four adjustable parameters and return two values.

You call it with whatever parameter values you want to use and it returns the output of that indicator.

So if you have an indicator (called myIndicator) that is as follows with adjustable variables of p1, t1, p2, t2 in that order:

ave1 = average[p1,t1]
ave2 = average[p2,t2]

return ave1, ave2

Then you call it in your strategy using:

ave1, ave2 = CALL"myIndicator"[50,0,100,1](close)

That would retrieve the 50 period simple moving average and the 100 period exponential average and your strategy would then store those values as ave1 and ave2

Define p1, t1, p2,t2 as 50,0,100,1 first then try.
