由于某些未知原因，一些阻力没有被绘制出来
Some resistance is not plotted for some unknown reason
我完成了支撑和阻力的代码。我为上一季度和一个月的高点和低点添加了额外的条件。它现在绘制得很好，但在某些情况下它没有绘制应该存在的阻力，我不明白为什么会这样。
绿色箭头代表支撑，红色箭头代表阻力。
在右侧的 2 个峰值处，应该绘制阻力红色箭头，因为价格穿过前一季度和一个月的低点，然后向上穿过前一周的高点，同时保持在前一季度和一个月的高点下方，但没有绘制任何东西.

// Resistance is not plotted 100% accurate, some are missing.
//-------------------------------
// 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.

这是您绘制阻力的原始绘图函数。因此，您的条件不仅是价格低于前一个月和前一季度的低点，而且 upTrend 也是一个条件。
我建议我们应该看看 not upTrend、isResistance、isResistanceM、isResistanceQ。请注意 not upTrend，因为您的情况正是这样，而不是 upTrend 本身。
使用 overlay=false 创建一个新指标，然后复制并粘贴您的原始代码。然后删除所有绘图功能并在最后添加以下代码。
plot(series=not upTrend ? 1:0, title="not upTrend", color=color.orange, linewidth=2)
plot(series=isResistance ? 1:0, title="isResistance", color=color.green, linewidth=2)
plot(series=isResistanceM ? 1:0, title="isResistanceM", color=color.red, linewidth=2)
plot(series=isResistanceQ ? 1:0, title="isResistanceQ", color=color.blue, linewidth=2)
所有这些变量都必须 TRUE 以便您的指标绘制任何给定蜡烛的阻力箭头。好吧，从技术上讲，upTrend 必须是 FALSE，因为您使用的是 not upTrend。我的意思是 not upTrend 必须评估为 TRUE.
如果您查看信号，您会发现橙色信号 (not upTrend) 在这些点上是 0。这就是阻止您的指标绘制阻力的原因。
所以，你应该看看 upTrend。
我们只能指出导致问题的原因。修复应该来自您，因为它是您的算法，是您检测上升趋势的方式。
但是，如果您认为 upTrend 的计算有问题，那是另一个话题，需要在这里提出另一个问题。
