The M-top is essentially the bearish converse of the W-bottom. An M-top can similarly be confirmed with a bearish MACD signal line crossover and indicates that the stock price will decline precipitously. Momentum stocks offer opportunities for traders to ride a wave of price action for short-term profits. However, to trade momentum stocks successfully, it’s important to recognize momentum early on and know when to exit a trade. Using the bands to indicate overbought/oversold conditions depends on the concept of mean reversion of the price. Mean reversion assumes that if the price varies considerably from the mean or average, it eventually reverts to its long-term average levels. Mean reversion trading attempts to capitalize on a security’s extreme price changes, assuming it will regress to its previous state.

bollinger bands help to determine how big is the deviation from the average price of a currency pair. The Bollinger Bands belongs to the default set of MetaTrader. You can add it to the chart by clicking “Insert” – “Indicators” – “Trend” and then choosing “Bollinger bands”. When bands contract in a narrow neck, the squeeze is highlighted by a sharp fall in Bollinger's Band Width indicator as in the Microsoft chart below. A move outside the band indicates that the trend is strong and likely to continue. If price quickly reverses, however, expect a swing to the opposite band as with the quick reversal in early August.

The classic M top is formed by a push to a high, followed by sell-off reaction, and then a test of the previous high. Watching the price behave like this, a trader may wonder if the stock is in a new uptrend, or if it has met its resistance. The upper and lower bands, by default, represent two standard deviations above and below the middle line .

What are Momentum Stocks?

Moving averages can be set to different timeframes, depending on the trader’s strategy. These include a simple moving average​ and exponential moving average​ . As explained earlier, two standard deviations show 95% of all the data while the market rates break the bands about 5% of the time. It simply indicates that the market is resisting further price increases which means that the pair is overbought. It’s recommended to use periods from 13 to 24, while the deviation should be in the range between 2 and 5. For example, it’s possible to use 50 and 2.1 for longer timeframes and 10 and 1.9 shorter timeframes. Notice that the smaller the period, the more trading opportunities will be offered by the indicator.

Once it’s executed, you could place an initial stop under the low of the breakout formation or under the lower band. Remember to adjust your stop orders as needed, or consider using a trailing stop designated in either a fixed dollar amount or a fixed percentage.

The BB can be used on all timeframes, although the indicator is more common for the intraday one. You can also apply the Bollinger bands to an oscillator that is drawn in a separate window below the price chart. For example, you can apply BB onto an RSI by selecting "Previous Indicator's Data" or "First Indicator's Data" in the Bollinger bands' "Apply to" drop-down menu. To make a conclusion, it would be wise to adjust the Bollinger bands for the asset you trade. If the price crosses the upper or the lower band too often, it’s necessary to increase the period. If the price rarely reaches the outer bands, there’s a sense to reduce the period. Subsequent rising troughs on Twiggs Money Flow would give me sufficient confidence to enter the trade before the next breakout, with a stop below the recent low at $56.
