During the last week, the price has declined below the moving average in the center of the Bollinger Bands. The Bollinger Bands are often used with a non-oscillator indicator like chart patterns or a trendline. The signals are considered more reliable if these indicators confirm the recommendation of the Bollinger Bands.

During the last week, the price has crossed below the 50 Day Moving Average.

Moving average crossover systems can be effective, but should be used in conjunction with trend patterns, momentum indicators, candlesticks and other aspects of technical analysis.
