SOL/USDT 合约策略 - 1分钟+5分钟双时间框架 V2 优化版 (Short Only)
|
||
|
||
基于原版优化：
|
||
1. 保持原版核心入场逻辑
|
||
2. 优化追踪止盈参数
|
||
3. 增强时间止损灵活性
|
||
4. 稍微放宽ATR过滤增加交易机会
|
||
|
||
核心设计：
|
||
1. 纯做空策略 - 价格必须低于EMA200至少1%才允许做空
|
||
2. 5分钟趋势确认：EMA12<EMA26<EMA50 + ADX 25-50 + RSI 30-48
|
||
3. ATR自适应波动率过滤
|
||
4. 1分钟精确入场：顶背离 / EMA死叉 / 熊市回调
|
||
5. 双重MACD确认（5分钟+1分钟MACD柱状图均为负）
