如何在 pine editor tradingview 中获取之前的文本或趋势线
How to get previous Text or trend line in pine editor tradingview
我正在使用 pine 编辑器在 TradingView 中进行编码，我正在使用 3 个超级趋势，现在是下降趋势，第一个超级趋势给出卖出 [红色] 信号并从向下的红线开始，然后第二个超级趋势给出卖出 [Orande in color] 信号并从向下的红线开始，与第三个超级趋势 [紫色] 类似的过程，在这里如果所有超级趋势都发出卖出信号，那么我需要显示一个大的父卖出信号，表明所有卖出条件已满足，现在如果其中一个信号变为绿色，表示买入信号，随后又变为红色，即卖出信号，则图表上应该再次显示母卖出信号。这暗示我需要从这里做空。
我附上了屏幕截图，你能帮我看看代码吗？
这里是代码供大家参考
