该策略通过计算多种趋势指标,在它们发生反转时进行买入和卖出操作。主要的趋势指标有TDI、TCF、TTF和TII。策略会在配置中选择使用哪一个指标来产生交易信号。
TDI指标基于价格的变化 momentum 来计算。通过 summing 和 smoothing 技术构建。当 TDI 方向指标上穿 TDI 曲线时做多,下穿时清仓。
TCF指标计算价格的正变化和负变化,来判断多头和空头的力量。当正变化力量大于负变化力量时做多,否则清仓。
TTF指标通过比较高点和低点的力量来判断趋势。做多的信号是 TTF 指标上穿 100, 反之则清仓。
TII指标结合了均线和价格区间来判断趋势反转。它同时考虑短期和长期趋势。做多信号是 TII 指标上穿 80,清仓是下穿 80。
进入做多和平仓的 logic 根据配置的指标来选择合适的交易信号。
该策略融合了多种常用的趋势交易指标,可以灵活适应市场环境。具体优势有:
该策略主要面临以下风险:
可以采取以下方法降低风险:
该策略可以从以下几个方面进行优化:
该策略结合多种趋势反转指标的优势,通过配置指标和参数进行优化,可以适应不同市场环境,在趋势反转点进行操作。关键是找到最优参数和指标组合,同时控制风险。通过持续优化和验证,可以构建稳定具有 alpha 的策略。

// Here is a collection of Trend Indicators as defined by M.H Pee and presented

//
// The actual implementation of the indicators here are made by: everget
//
// I have gather them here so that they easily can be tested.
//
// My own test was made using 15 companies from the OMXS30 list
// during the time period of 2016-2018, and I only went LONG.
//
// The result was as follows:
//
// Average Std.Dev
// profit
// TDI 3.04% 5.97
// TTF 1.22%. 5.73
// TII 1.07% 6.2
// TCF 0.32% 2.68
