Any level on the Y access inside the range with only one TPO.
Single Prints are a form of weakness and increase the odds of backfilling (returning to where they start) but often “the base” or start of the single prints then acts as support or resistance.
If single prints remain at the close of the range (end of the day), they are the start of new distribution. Meaning we think of them as separate days, the new day starting at the base of the single prints.
