{==============================================================================}
{系统说明：}
{1. 鳄鱼线系统：颚部(蓝)、牙齿(红)、嘴唇(绿)三条线}
{2. 分形突破：上分形突破做多，下分形跌破做空}
{3. 四种做多模式：分形突破、鳄鱼金叉、趋势回调、鳄鱼觉醒}
{4. 四种做空模式：分形跌破、鳄鱼死叉、趋势反弹、鳄鱼觉醒}
{5. 笑脸图标：笑脸(强多)、加号笑脸(中多)、哭脸(强空)、减号哭脸(中空)}
{6. 成交量过滤：避免无量突破假信号}
{7. 趋势状态显示：清晰显示鳄鱼状态（醒、睡、眠）}

🎯 核心信号说明：

做多信号（笑脸系列）：

  1. 😊 笑脸（最低位置）：分形突破 + 鳄鱼张嘴（最强信号）

    • 条件：突破上分形 + 鳄鱼多头排列 + 嘴张开

  2. ⊕ 加号笑脸：鳄鱼金叉（强信号）

    • 条件：嘴唇线上穿牙齿线 + 鳄鱼多头排列

  3. ↑ 上箭头：趋势回调（中等信号）

    • 条件：价格回踩牙齿线 + 鳄鱼多头

  4. 买 买字：鳄鱼觉醒（弱信号）

    • 条件：从睡觉状态转为多头排列

做空信号（哭脸系列）：

  1. 😢 哭脸（最高位置）：分形跌破 + 鳄鱼张嘴（最强信号）

    • 条件：跌破下分形 + 鳄鱼空头排列 + 嘴张开

  2. ⊖ 减号哭脸：鳄鱼死叉（强信号）

    • 条件：嘴唇线下穿牙齿线 + 鳄鱼空头排列

  3. ↓ 下箭头：趋势反弹（中等信号）

    • 条件：价格反弹至牙齿线 + 鳄鱼空头

  4. 卖 卖字：鳄鱼觉醒（弱信号）

    • 条件：从睡觉状态转为空头排列

鳄鱼状态解读：

  • 鳄醒：多头排列（嘴唇>牙齿>颚部）
  • 鳄睡：空头排列（嘴唇<牙齿<颚部）
  • 鳄眠：三线纠缠（震荡行情）
  • 嘴开：三线分开，趋势明确
  • 嘴闭：三线接近，趋势不明

⚡ 使用建议：

  1. 重点关注笑脸/哭脸信号：这些是分形突破信号，可靠性最高
  2. 配合鳄鱼状态：只在"鳄醒"时做多，"鳄睡"时做空
  3. 注意张嘴状态："嘴开"时趋势强劲，"嘴闭"时谨慎操作
  4. 成交量确认：启用成交量过滤，避免假突破

这套系统特别适合趋势明确的行情，在鳄鱼线张开时能捕捉到主要的趋势行情，分形突破提供了精确的入场点。笑脸/哭脸图标让你一眼就能识别最强的交易机会。
