Non-trend Tools
Momentum oscillators, such as RSI, stochastics, or MACD, are a favorite indicator of many traders and their utility is best applied to non-trending or sideways markets. The primary use of momentum indicators is to gauge whether a market is overbought or oversold relative to prior periods, potentially highlighting a price reversal before it actually occurs.
However, this application fails in the case of a trending market, as the price momentum can remain overbought/oversold for many periods while the price continues to move persistently higher/lower in line with the underlying trend. The practical result is that traders who rely solely on a momentum indicator might exit a profitable position too soon based on momentum having reached an extreme level, just as a larger trend movement is developing. Even worse, some might use overbought/oversold levels to initiate positions in the opposite direction, seeking to anticipate a price reversal based on extreme momentum levels.
The second use of momentum oscillators is to spot divergences between price and momentum. The rationale with divergences is that sustained price movements should be mirrored by the underlying momentum. For example, a new high in price should be matched by a new high in momentum if the price action is to be considered valid. If a new price high occurs without momentum reaching new highs, a divergence (in this case, a bearish divergence) is said to exist. Divergences frequently play out with the price action failing to sustain its direction and reversing course in line with the momentum.
In real life, though, divergences frequently appear in trending markets as momentum wanes (the rate of change of prices slows) but prices fail to reverse significantly, maintaining the trend. The practical result is that counter-trend trades are frequently initiated based on price/momentum divergences. If the market is trending, prices will maintain their direction, though their rate of change is slower. Eventually, prices will accelerate in line with the trend and momentum will reverse again in the direction of the trend, nullifying the observed divergence in the process. As such, divergences can create many false signals that mislead traders who fail to recognize when a trend is in place.
