我收到错误：不能使用可变变量作为安全函数的参数
这是显示 3 条线作为阻力线、中间线和支撑线的代码。

我在写这篇文章时遇到了错误
red_W = security(syminfo.tickerid, "1W", Resistance_line_red, barmerge.gaps_off, barmerge.lookahead_on)
green_W = security(syminfo.tickerid, "1W", Support_line_green, barmerge.gaps_off, barmerge.lookahead_on)
orange_W = security(syminfo.tickerid, "1W", Average_line_orange, barmerge.gaps_off, barmerge.lookahead_on)
我已经阅读了许多类似的问题，以了解我可能需要将它们全部放入一个函数中，因此它可能会起作用，但我不知道如何应用于此特定代码。
请帮忙，我想让它们在较低的时间范围图表中使用，如下所示：
if (close < red_W)
//
if (close < green_W)
//
if (close < orange_W)
//
