hi support! I used the indicator from the examples https://yadi.sk/d/9bdMI3o-3Q3GcF
The indicator set the level https://yadi.sk/i/AM927eeY3Q3GSV in JFOREX2. Retained in the template https://yadi.sk/d/8oZvenH93Q3Hpu.
Then I start the new version JFOREX3 and load template. Result on the picture https://yadi.sk/i/G7MxeQjN3Q3GgB: the line of the level is gone.
The next two pictures show that the values startIndex are different
JFOREX3:https://yadi.sk/i/rTmx1kVD3Q3JDq
JFOREX2 :https://yadi.sk/i/bMmxFe-43Q3JAC
The result is obtained using the code

 public IndicatorResult calculate(int startIndex, int endIndex) {
        //calculating startIndex taking into account lookback value
        context.getConsole().getOut().println(" start="+startIndex+" end="+endIndex);

It is a known issue. But it is not going to be amended.
