Many discussions of trend on this board centered on identifying general trend. However, little discussions are found on the issue of gauging the strength of a trend. It is the purpose of this thread to share ideas that will aid a trader identify quality trend to follow. Most of you are probably familiar with a trend-following strategy. It is said that when a trend is identified, the likelihood that it will continue is high. I am not here to refute this hypothesis, but rather to elaborate on it. Assuming that this hypothesis has merits of its own, if a trader picks a quality trend to follow the probability of him/her making a profit is even higher than just following any trends. But how does one identify a quality trend? Let's say that you have identified two possible up trends to follow (short, medium, long, or whatever your outlook is). One is showing that the price is increasing at an increasing rate, and the other's price is increasing at a decreasing rate. Now, which would you choose to follow? Why? Does your answer address your question on how to identify the strength of a trend, now?
