该策略基于快速均线和慢速均线的交叉来决定做多做空。当快速均线上穿慢速均线时做多,当快速均线下穿慢速均线时平仓。为了追求更高的利润,该策略采用了追踪止损机制。做多之后,并不直接在成交价下方设置止损价,而是在成交价下方设立一个追踪止损价,这个追踪止损价会随着价格上涨而上移,直到价格下跌触发止损价的下限。
该策略使用快速简单移动平均线(SMA)和慢速SMA来决定做多和平仓的时机。当快速SMA上穿慢速SMA时,判断趋势变为上涨,此时做多;当快速SMA下穿慢速SMA时,判断趋势反转,准备平仓。
为了追求更高的利润,该策略引入了追踪止损机制。做多之后,并不会在固定价格设置止损单,而是设立一个追踪止损价,它会随着价格上涨而向上追踪,每次价格上涨一定比例后,追踪止损价就会向上调整一定幅度。当价格出现回调,触碰到追踪止损价时,会触发止损单,将头寸平仓。
具体来说,追踪止损价的计算公式为:
追踪止损价 = 价格 × (1 - 止损追踪百分比)
其中,止损追踪百分比由策略参数“Deviation %”设定。策略会在开仓后每次K线收盘时计算新的追踪止损价。新的追踪止损价不能低于上一根K线的追踪止损价,以确保止损价只能上移,不能回落。
当价格下跌,触及追踪止损价时,会触发平仓信号,头寸会使用市价单平仓。
本策略综合利用均线指标判断趋势方向,以及追踪止损机制锁定利润,在训练数据中表现不俗。通过优化参数组合,控制风险,有望获得稳定收益。但任何策略都无法完全避免亏损,建议适当调整仓位管理,测试不同品种,分散风险。

// Description
// =============================================================================
// This strategy will go long if fast MA crosses over slow MA.
// If the 'Enable Trailing` is checked then the strategy instead of exiting from the position
// directly it will follow the price upwards (percentagewise) with small steps
// If the price drops by this percentage then the exit order will be executed
//
// The strategy has the following parameters:
//
// Fast SMA Length - How many candles back to calculte the fast SMA.
// Slow SMA Length - How many candles back to calculte the slow SMA.
// Enable Trailing - Enable or disable the trailing
// Deviation % - The step to follow the price when the open position condition is met.
// Source Exit Control - The source price to compare with the exit price to trigger the exit order when trailing.
