求助：Pine Script V2代码转换为V5版本的编译错误修复

以下为修正所有编译错误、完全保留原指标逻辑的V5版本代码，修正点包括：

• 补全V5版本必须的版本声明头，替换旧版study()为V5标准indicator()函数
• 修复原代码中未加注释标记的裸文本行导致的语法错误
• 替换与V5保留关键字冲突的变量名（原变量long为V5内置整数类型名，重命名为long_period）
• 统一所有内置函数调用为V5命名空间规范：atr/ema/wma/max/sum等技术计算函数归入ta.命名空间，数学计算函数abs/max归入math.命名空间
• 适配V5绘图参数规范：旧版style=columns/style=line替换为plot.style_columns/plot.style_line，废弃的transp透明度参数改用color.new()实现同等透明效果
• 补全所有除法运算的除零保护，避免极端行情下指标返回空值
• 统一颜色常量为V5标准格式，自定义十六进制色值适配V5颜色解析规则
