We have to be careful with the terms being used here; A trader is not the same as an investor. A trader is thinking short term and an investor is thinking long term. Most of the people who lost after the last bull run were traders. An good investor would have done his research, and brought with the intention of holding for at least a few years. It seems that your post is targeted towards investors which in that case some of the advice presented is largely irrelevant (price, TA).
