修复TradingView中Woodie's Pivots指标无法绘图的问题

问题诊断 #

代码无法在图表上显示的核心原因有两个：

• 公式错误：原始代码中Woodie枢轴中值wpm的计算未除以4，导致数值严重偏离当前价格区间，线条不在图表可视范围内。
• 跨周期数据逻辑问题：使用ticker.new指定会话后，非日线图表上的todayOpenp获取存在同步问题，进一步导致数值异常。

修正后的完整代码 #

//@version=5
indicator(title="Woodie's Pivot Points", shorttitle = "WPP", overlay=true, max_lines_count=500, max_labels_count=500)
//Inputs
PlotWP = input.bool(title = "绘制Woodie枢轴点?", defval=true)
resp = input(title="分辨率", defval="D")

// 直接使用当前品种ID获取跨周期数据，避免会话冲突
yesterdayHighp = request.security(syminfo.tickerid, resp, high[1], gaps=barmerge.gaps_off, lookahead=barmerge.lookahead_on)
yesterdayLowp = request.security(syminfo.tickerid, resp, low[1], gaps=barmerge.gaps_off, lookahead=barmerge.lookahead_on)
todayOpenp = request.security(syminfo.tickerid, resp, open, gaps=barmerge.gaps_off, lookahead=barmerge.lookahead_on)

// 修正Woodie枢轴点标准计算公式
wpr = yesterdayHighp - yesterdayLowp
wpm = (yesterdayHighp + yesterdayLowp + 2 * todayOpenp) / 4  // 关键：添加除以4的步骤
wpr1 = (2 * wpm) - yesterdayLowp
wpr2 = wpm + wpr
wpr3 = yesterdayHighp + 2 * (wpm - yesterdayLowp)
wpr4 = wpr3 + wpr
wps1 = (2 * wpm) - yesterdayHighp
wps2 = wpm - wpr
wps3 = yesterdayLowp - 2 * (yesterdayHighp - wpm)
wps4 = wps3 - wpr 

// 绘图逻辑
plot(PlotWP ? wpm : na, "Woodie枢轴中值", color.black, linewidth = 1, style = plot.style_linebr)
plot(PlotWP ? wpr1 : na, "Woodie阻力位1", color.olive, linewidth = 1, style = plot.style_linebr)
plot(PlotWP ? wps1 : na, "Woodie支撑位1", color.maroon, linewidth = 1, style = plot.style_linebr)
plot(PlotWP ? wpr2 : na, "Woodie阻力位2", color.olive, linewidth = 1, style = plot.style_linebr)
plot(PlotWP ? wps2 : na, "Woodie支撑位2", color.maroon, linewidth = 1, style = plot.style_linebr)
plot(PlotWP ? wpr3 : na, "Woodie阻力位3", color.olive, linewidth = 1, style = plot.style_linebr)
plot(PlotWP ? wps3 : na, "Woodie支撑位3", color.maroon, linewidth = 1, style = plot.style_linebr)
plot(PlotWP ? wpr4 : na, "Woodie阻力位4", color.olive, linewidth = 1, style = plot.style_linebr)
plot(PlotWP ? wps4 : na, "Woodie支撑位4", color.maroon, linewidth = 1, style = plot.style_linebr)

核心修正说明 #

• 公式修复：Woodie枢轴点的中值标准公式为(昨日高点 + 昨日低点 + 2×今日开盘价) ÷ 4，原始代码遗漏了除以4的步骤，导致数值偏离正常价格范围。
• 跨周期数据优化：替换ticker.new为syminfo.tickerid，避免会话设置引发的数据同步问题，确保跨周期数据获取准确。
• 计算逻辑简化：将阻力位2和支撑位2的计算简化为wpm ± wpr，符合Woodie枢轴点的标准定义，同时减少冗余计算。
