15:28:30 Strategy tester: java.lang.IllegalArgumentException: Illegal Capacity: -2048076884 @ jforex.MandelbrotDaily.testCandleInterval(MandelbrotDaily.java:193)
Got this message for the first time in relation to code that has been working fine for a very long time. The line is for the calculation of a 25 period EMA. It affects all the Historical Testers (Live and Demo) but only for the 4 hour interval calculations.
Can you help?

Please provide an example strategy which replicates the case. Please provide Historical Tester settings that you use.

Thanks for coming back so fast. I believe I have found the problem: I was trying to get an indicator in the onStart method. I can now understand why this would not be a valid location, as the indicator (EMA) requires bar information / SMcK
