Incomplete plot when using "setIntervalsBackfill(true);" on 100T cht & 2 min study

[waynecd]

Using the "CUSTOMMACD" study in ver 11.2 "Built-in Studies Formulas" folder on a 100T chart of "6E #F" with "setIntervalsBackfill(true);" in the preMain() and applying a 2 minute interval to the study, the plot abruptly stops about an hour back.

If I don't use "setIntervalsBackfill(true);" it plots fine.

Please advise if this is an expected result or a bug.

In case it wasn't clear:

A 2 minute interval is used for the "CUSTOMMACD" study on a 100T chart of "6E #F" in ver 11.2. This is when it stops plotting when you add "setIntervalsBackfill(true);" to premain.
