I use the inputs array from startIndex to endIndex to determine outputs, the problem I observe here causes an ArrayIndexOutOfBoundsException,
under what circumstances does this / is this supposed to happen?
iconsole() output

INPUT LENGTH DOES NOT AGREE WITH INDICES.

ERROR Indicators - 3999 <--------- attempt to output endIndex IBAR causes this
java.lang.ArrayIndexOutOfBoundsException: 3999
Error in indicator: java.lang.ArrayIndexOutOfBoundsException: 3999 @ calculate(myIndicator.java:44)
3999: java.lang.ArrayIndexOutOfBoundsException: 3999
all calls to calculate return as follows (lookback = 0, lookforward = 0):
result.setFirstValueIndex(startIndex);
result.setLastValueIndex(endIndex);
result.setNumberOfElements((endIndex - startIndex) + 1);
The context of this all is the Historical tester run during:
2012-09-27 13:52:15.199 INFO testgui - DATE FROM: 04/03/2012 22:10:00 GMT

Please provide an example indicator which replicates the issue. Also please provide more precise Historical Tester settings and also the strategy that you launch in the Historical Tester.
