Update: it is every trader's dream to Enter at absolute bottom and Exit at absolute top for long trades and vice-versa for Short Trades. With this demand in mind, some new code has been inserted in the indicator which tries to pick up these tops and bottoms of up and down moves.
Indicator prints PEOB (probably end of buying pressure) and PEOS (probably end of selling pressure) when it thinks buying pressure or selling pressure is dying. Traders must note that the candle where PEOB or PEOS is printed, should be taken as a milestone and they can exit their positions (partially or fully) when following candles confirm the end of buying or selling wave.
The criteria for printing of PEOB or PEOS is very strict and these marks will occur rarely, however, there is no 100% guarantee that every time market will respect PEOB or PEOS symbol, though there is very high probability that turning points will occur around these milestones.
