求助：将Pine Script v2版本VWAP指标转换为v5版本报错

遇到的错误 #

错误位置565:28：未声明标识符'bool'；错误位置565:23：'input'函数不存在名为'type'的参数；错误位置566:23：'input'函数不存在名为'type'的参数；错误位置567:24：'input'函数不存在名为'type'的参数；错误位置568:24：'input'函数不存在名为'type'的参数；错误位置570:29：'input'函数不存在名为'type'的参数；错误位置572:18：未声明标识符'tickerid'；错误位置572:9：无法找到函数或函数引用'security'

核心错误修正点 #

• 布尔输入参数：v5不再支持input(..., type=bool)写法，需改用input.bool()函数声明布尔类型输入
• 行情引用逻辑：v2的security()函数替换为v5的request.security()，原tickerid变量替换为syminfo.tickerid
• 语法细节调整：v2的style=circles需改为plot.style_circles，sqrt/max需改为math.sqrt/math.max，study替换为indicator

修正后的完整v5代码 #

//@version=5
indicator("VWAP Stdev Bands v2 Mod", overlay=true)

// 标准差参数输入
devUp1 = input.float(1.28, title="Stdev above (1)")

devUp5 = input.float(4.01, title="Stdev above (5)")
devDn5 = input.float(4.01, title="Stdev below (5)")

// 显示开关参数（改用v5的input.bool）
