Hello,

I need S&R indicator form H1 timeframe on m30 timeframe.
But after compiling this line:
IIndicatorsProvider indicatorsProvider = context.getIndicatorsProvider();
srIndicator = indicatorsProvider.getIndicator("S&R");


I get error. Maybe it's a wrong name or something else.
Please support, help me.

This is error after compiling source code:
08:19:46 ----------
08:19:46 srIndicator cannot be resolved
08:19:46 ^^^^^^^^^^^
08:19:46 srIndicator = indicatorsProvider.getIndicator("S&R");
08:19:46 1. ERROR in C:\Users\andymen\AppData\Local\Temp\jfxide\tmp\compile\SRm30.java (at line 17)
08:19:46 ----------
08:19:45 Compiling SRm30.java


I've just started writting this indicator and that's why this code is so short.
Base code is form tutorial on wiki website and I added only few lines.

I hope this is helpfull

You have not defined the variable type. Consider using some IDE like Eclipse or Netbeans for writing your code, such that you can receive immediate fix suggestions, see:

Thank you for help. I've fixed this, but it's another problem.
This exception is thrown continously:

09:47:21 Error in indicator: java.lang.ArrayIndexOutOfBoundsException: 1 @ jforex.SRm30.calculate(SRm30.java:40)

I think it's caused by 
timePeriod
variable, but I don't know how is computed S&R indicator.
Could you send me some descritpion of this indicator?
I know that function compute() takes 2 int arguments but what are they?

I need to use S&R indicator from JForex but I want to draw dots from H1 timeframe on m30.
Please feed me back information about an used algorithm to calculate this dots or what are function parameters in 
IndicatorResult calculate(int arg0, int arg 1)

All I know is a fact that S&R indicator is not using any timeframe parameter but I need do overload function calculate() or write my own version based on algorithm used in S&R indicator.
Maybe my thinking is wrong and there is a better solution of my problem.
Please help.

I have read it but the problem in my indicator is timeframe. S&R indicator calculates dots on an active chart window on current timeframe. I don't know any way to change that because if I change timeframe on chart so the indicator changes placement of dots. There's no a parameter like timeframe in a calculate() function.
I repeat that again: I need an algorithm used in S&R or some way of overloading it with a timeframe parameter.
Could you please give me algorithm for S&R or an oveloaded calculate() function with timeframe parameter?

You don't need to change the calculate rather, the inputs, such that they work with a certain timeframe, see:
