Hello

I asked you how to access values from my custom indicator inside strategy code.

Your replay was this:

Object[] val = indicators.calculateIndicator(
                    instrument,
                    period,
                    new OfferSide[] {OfferSide.BID, OfferSide.BID},
                    "LS_I_DirectionalCorrelation_vs_GBPUSD",
                    new IIndicators.AppliedPrice[] {IIndicators.AppliedPrice.CLOSE},
                    new Object[] {14},
                    1);
console.getOut().println('indicator value: ' + val[0]);

I then I told that its working fine.
But now I found out that sometimes is NOT.
I run the code in historical tester and its printing the values of the indicator.
But for example another time, I run THE SAME CODE on THE SAME DATA in historical tester but all the calculated values are NaN.

How is this possible???

Hello
I found out how to resolve the problem by myself...
as I told sometimes happens that when you are using multiinstrument indicators in your strategies, all their results are still Double.NaN

In this case is necessery to restart JForex
after that load and display charts of all instruments which are used by your multiinstrument indicator.
The charts has to be displayed with period 1Tick and after that change to any bigger period (i am using 1hour)
This will cause something like "initializing or subscribing the data source into JForex" (thats how I am explaining it to myself )
and then the indicators can be used without any problem

It is quite unusually behaviour mayebe there is any bug maybe your developer might take a look at this issue.
