If you run a strategy in Historical Tester and a position does not get closed, the p/l is not recognized.
Example given
Run the attached EquityBug.jfx, deposit = 100'000 USD, USD/JPY, testing period: yesterday, visual mode on, Show reports on
If you run this on the current JForex 3.4.13 you will get a different strategy report result than running this on JForex 2.45.77!
(The result on JForex 2 is slightly different. I am also not sure why there is this imprecision between JForex 2 and 3, but it is in a range which is ok for the moment.)
Please compare the equity development screenshot of JForex3 with the strategy reports of both systems.
