核心逻辑
这是一个基于MACD指标的综合增强版技术分析系统。公式以经典的MACD（12,26,9）为核心，通过DIF线与DEA线的交叉关系判断趋势方向，同时叠加了KDJ指标进行辅助验证。系统内置了压力线、支撑线、趋势线等多重技术工具，能够识别底背离、顶背离、W底形态、二次金叉等经典技术信号，并通过短期小周期（3日）MACD进行背离辅助判断。此外还包含基于价格波动和成交量的VAR系列指标用于捕捉止跌信号。
买卖信号
1. **MACD金叉**：DIF上穿DEA，买入信号
2. **MACD死叉**：DIF下穿DEA，卖出信号
3. **底背离**：DIF底背离（价格新低但DIF未新低），买入信号
4. **顶背离**：DIF顶背离（价格新高但DIF未新高），卖出信号
5. **W底形态**：出现W底形态时买入
6. **二次金叉**：DEA<0区域内的二次金叉，强化买入信号
7. **低位金叉**：DIF<-0.1时的金叉，更明确的买入信号
8. **MACD顶背/底背**：通过KDJ与MACD结合判断背离
9. **止跌信号**：满足特定条件时显示"止跌"提示
用法
1. **基础用法**：红DIF线上穿白DEA线形成金叉时考虑买入，下穿时考虑卖出
2. **背离验证**：当出现底背离或顶背离信号时，结合DIF与DEA的位置关系确认趋势转折
3. **形态辅助**：关注W底、二次金叉等强化信号，配合压力支撑线判断买卖时机
4. **多周期参考**：同时观察长期MACD和短期（3日）MACD的小顶背离信号，提高判断准确性
5. **综合判断**：建议结合成交量和其他技术指标综合分析，避免单一信号决策
