Another thing related to rollover calculation I've noticed recently, although it's probably not a big issue:

When testing with T1 data I get sometimes different values than with T6 data. Is there a reason for that?

Example:
Code:
Type	        Open	                Close	                Entry	Exit	Profit	Roll
T1: Short	2014-01-10 19:00	2014-01-13 01:00	1.36704	1.3663	8.34	1.42		
T6: Short	2014-01-10 19:00	2014-01-13 01:00	1.36704	1.3663	9.76	2.84

T1: Long	2014-03-14 15:00	2014-03-17 07:00	1.39163	1.39024	-17.94	-4.94		
T6: Long	2014-03-14 15:00	2014-03-17 07:00	1.39163	1.39024	-22.88	-9.88
