What is a balanced price range (BPR)?
First, a sharp drop leaves a bearish gap. Then a sharp rally the other way leaves a bullish gap that overlaps the first. The shared part of the two gaps is the balanced price range: both sides have already been “offered” there, so price often reacts on the return.
In a bullish BPR — formed by the rally — traders look for longs on the pullback into the overlap; in a bearish one, shorts.
