Break of trendline It might not be bottom, Surely buy bias

A broken trendline is a technical signal that can suggest a change in trend is at hand.
If low volume (rather than high volume) accompanies the break of a trendline, the signal is not as strong or convincing.
It can make sense to wait a day or two to make sure that the trendline break is legitimate.
Once a position is opened, risk management—in the form of stop-loss orders or trailing stops—can help protect profits after a trendline break.
Low volume is sometimes a concern for technical traders because it can suggest that bears were not as interested in pushing the price sharply lower as most were expecting. Given the low volume and lack of volatility, the best move is sometimes to wait several days to confirm that the bulls will not be able to send the stock price back above the trendline
