During the last week, the price has moved above the moving average in the center of the Bollinger Bands.

During the last week, the price has advanced above the 50 Day Moving Average. While the medium-term trend is down and daily technical indicators are overbought, the 50 Day Moving Average is considered a resistance level. The moving average crossover signals work better when the stock develops a strong trend, but they are ineffective when the stock is in a trading range. 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.
