Hello,
I probably found a Bug in the Hhistorical Tester.
When I'm trying to load the latest RangeBar, I get a Exception:
"java.lang.NullPointerException @ jforex.rangebartests.Example.onStart(Example.java:21)"

In Live-Mode (on a Demo-Acc.) this works just fine.

see the Example below

We could not be able to reproduce it. Could you please elaborate on the issue. Any specific conditions and/or settings?

I use the following Settings:

    - EURUSD
    - LastMonth
    - Ticks - process all Ticks

I get the following output in the JAVA-Console:

The Date of the *.bi5 Files changes through several Years.
It seems like JF is searching for the Bar but can't find it,
after a While the NullPointerException is thrown.
I`ve already deleted my Cache, without any Effect.
