该策略结合了相对强弱指数(RSI)和布林带(Bollinger Bands)两个技术指标,当价格低于布林带下轨时产生买入信号,当价格高于布林带上轨时产生卖出信号。该策略只有在RSI指标和布林带指标同时处于超卖或超买状态时才会触发交易信号。
RSI和布林带双重策略通过结合趋势和动量指标,能够比较全面地判断市场状态,并给出相应的交易信号。但该策略在震荡市中表现可能欠佳,且未设置风险控制措施,因此实盘运用时需要谨慎。通过优化参数、引入其他指标和设置合理的止损止盈等方式,可以进一步提升该策略的稳定性和盈利能力。

// ChartArt's RSI + Bollinger Bands, Double Strategy - Update
//
// Version 1.1
// Idea by ChartArt on January 18, 2015.
//
// This strategy uses the RSI indicator
// together with the Bollinger Bands
// to sell when the price is above the
// upper Bollinger Band (and to buy when
// this value is below the lower band).
//
// This simple strategy only triggers when
// both the RSI and the Bollinger Bands
// indicators are at the same time in
// a overbought or oversold condition.
//
// In this version 1.1 the strategy was
// both simplified for the user and
// made more successful in backtesting.
