Trading View 振荡器中多个因素的交叉函数
Crossover function for multiple factors in an oscillator on Trading View
我想在 Trading View（开源，震荡指标）上为以下指标添加警报。简而言之，必须满足多个条件才能触发不同类型的警报（多头入场、多头早出、多头晚出、空头入场、空头早出、空头晚出）。我有三个因素，slowMA + fastMA + 基于 RSI 或移动平均线的中线 (midl)。
多头进场：slowMA 向上交叉 fastMA + slowMA 向上交叉 midl + fastMA 向上交叉 midl
多头提前退出：fastMA 向上交叉 slowMA + slowMA 向上交叉 midl + fastMA 向上交叉 midl
多头后期退出：fastMA 向上交叉 slowMA + midl 向上交叉 slowMA + midl 向上交叉 fastMA
空头进场：FastMA 向上交叉 slowMA + midl 向上交叉 slowMA + midl 向下向上交叉 fastMA
空头提前退出：slowMA 向上交叉 fastMA + midl 向上交叉 slowMA + midl 向上交叉 fastMA
空头尾盘：slowMA 向上交叉 fastMA + slowMA 向上交叉 midl + fastMA 向上交叉 midl
我以前完全没有编码经验。我收到以下错误。非常感谢您的帮助！:

表示您正在尝试在函数 crossover 中使用绘图，这不是兼容的选项：您应该将 series[float] 传递给它。
在您的 crossover() 函数中，尝试使用 mid 而不是 midl，例如：
longopen = crossover(slowMA, fastMA) and crossover(fastMA, mid) and crossover(slowMA, mid)
