需要绘制所有相关蜡烛的支撑和阻力，但它只在交叉点绘制
Need to plot the support and resistance @ all relevant candles, but it is only plotting at crossover
我想在价格上穿前一季度高点和前一个月高点，然后下穿上周低点时绘制所有蜡烛的支撑，收盘价变为一个支持。
只要价格保持在前一周 高位 以下，每次收盘都成为支撑。只要价格不低于上季度低点 或 上月低点，这种情况就会持续，支撑也会停止。它现在只在交叉处绘制。
抵抗则相反。

//-------------------------------
// support
// If the price crosses above the previous quarter high and previous month high, and then crosses down the previous week low, the close becomes a support.
//As long as the price stays then below the previous week high, each close becomes a support. The condition remains as long as the prices do not cross
//below previous quarter low OR previous month low, then support also stops.
//-------------------------------
// resistance
// If the price crosses below the previous quarter low and previous month low, and then crosses up the previous week high, the close becomes a resistance.
// As long as the price stays then above the previous week low, each close becomes a support. The condition remains as long as the price does not cross
// above previous quarter high OR previous month high, then resistance also stops.

每当我遇到问题时，我总是使用 study(overlay=false) 克隆我的代码并绘制一些我怀疑导致问题的信号。
因此，在您的情况下，您可以将代码复制并粘贴到新指标并在末尾添加以下行。请删除所有其他 plot() 函数。否则，您将遇到缩放问题并且结果不会那么明显。
//plot support & resistance
plot(series=upTrend ? 1:0, color=color.orange)
plot(series=crossunder(close, prevWeekLow) ? 1:0, color=color.green)
plot(series=crossover(close, prevWeekHigh) ? 1:0, color=color.red)
这是结果：
如果你仔细观察，这里的问题是 crossover() 和 crossunder() 函数 return 一个 BOOL 值只有当 crossover/crossunder 发生时。因此，您在 plot 函数中的条件变为 TRUE 仅一根柱。
您需要做的是弄清楚如何为 crossover/crossunder 保持信号 TRUE，直到遇到相反的信号。
为此，我建议您开始使用 v4。然后你可以使用 var 关键字。使用 var 关键字创建的变量会保留它们的值，直到您覆盖它们。因此，您可以执行以下操作：
var isSupport = false
var isResistance = false
if (crossunder(close, prevWeekLow))
isSupport := true
isResistance := false
if (crossover(close, prevWeekHigh))
isSupport := false
isResistance := true
