Maybe the trend is ending

maybe downtrend is ending. I have my ideas about it:
1. The price went up from yellow rectangle several times. It means that there is a high probability that we have trend reversal and we might get uptrend.
2. lets say price goes up to pink triangle and hold for a long time . Trend reversal probability will be even higher And we might get uptrend.
3. If the price goes down from yellow rectangle then the trend probably will continue.
