I suspect this is a copy paste error, meaning two strategies are mixed together. From what I understood is this strategy does not have an EA (Expert Advisor). You simply plot the RS (14) and Bollinger Bands on your chart and look for divergences in RSI together 什麼是布林通道(Bollinger Band) with spikes outside the Bollinger Bands as described in "Rules for Buy / Sell Signal". Keep in mind that RSI can stay overbought for a longer period of time when the trend is strong. A one off divergence does not necessary mean a trend change. It is a good countertrend strategy for pullbacks. Always look at the higher timeframe.
