Gold – Weekly look on Bollinger Band

On the weekly XAUUSD chart, I marked the bounces of gold_prices between upper BB, median line and lower BB…. Bollinger bands seems to have worked pretty well, which might give us a clue.
Engulfing red candles clearly indicate the strength of bears in the market. Now we are on the median line of Bollinger Band, where we might see a reaction of bulls. Otherwise, lower BB is on the way.
