I am not sure about that, but I think that it is related to the TF, if you apply 5 pips to a 5-minute TF, then the confirmation is at least AFTER 5 minutes (or more, if needed), if there’s a spike of 6 pips before 5 minutes have elapsed, then a new bar will open, but as soon it falls back under 5 it’s deleted because 5 minutes have not elapsed and focus is given back to the “old” (not anymore) candle which is still formin within the 5-pip range and 5-minute TF.
There are TWO limits, range & time, pips make up for new bars, but each one must also be confirmed by selected time frame.
