Now may be a good time for technical traders to reinforce their thinking about why trading in the direction of the prevailing trend is considered the major underpinning of technical analysis in the pursuit of consistent, long run, aggregate, net trading profits. Following are some issues raised by John Murphy. Let's see what he says.
"The concept of trend is absolutely essential to the technical approach. The whole purpose of charting the price action of a market is to identify trends in early stages of their development for the purpose of trading in the direction of those trends."
"The entire trend-following approach is predicated on riding an existing trend until it shows signs of reversing."
"In a general sense, the trend is simply the direction of the market, which way it's moving."
"The fact of the matter is that markets actually move in three directions-up, down, and sideways. It is important to be aware of this distinction because for at least a third of the time, by a conservative estimate, prices move in a flat, horizontal pattern that is referred to as a trading range. (So in a market like ours, where short selling is not allowed by the local stock exchange-contrary to the unfounded claims of a few who insist that it is-long trades are bound to be unprofitable two-thirds of the time.)"
"There are three decisions confronting the trader-whether to buy a market(go long), sell a market(go short) (again, not allowed by the local exchange), or do nothing(stand aside). When a market is rising, the buying strategy is preferable. When it is falling, the second approach would be correct (ditto-not in our market). However, when the market is moving sideways, the third choice-to stay out of the market-is usually the best."
"Most technical tools and systems are trend following in nature which means that they are primarily designed for markets that are moving up or down. They usually work very poorly, or not at all, when markets enter these lateral or "trendless" phases. It is during these periods of sideways market movement that the technical traders experience their greatest frustration, and systems traders their greatest equity losses. A trend following system, by its very definition, needs a trend in order to do its stuff. The failure here lies with the trader who is attempting to apply a system designed for (following) trending markets into a nontrending market environment (or trading against the prevailing direction of the trend)."
