I don't know the reason for your results. But, you might try simplifying by just checking if the bars have the same DateNum, Day, DayOfWeek, DayOfYear or DaysSince1900.
One thing to verify before going ahead is whether or not your backtest would work using today as your last in range date. Will it still work when there is no tomorrow's bar to check against?
