求助修改Pine Script：仅显示当日高低线不向后延伸

修改后代码 #

//@version=5
indicator(title="_CM_High_Low_Open_Close", shorttitle="_CM_H_L_O_C", overlay=true)

yellow_color = color.new(color.yellow, 0)

// Inputs
st = input(true, title="THL")
swt = input(false, title="WHL")
swy = input(false, title="Prvs-WHL")
smh = input(false, title="MHL")
spmh = input(false, title="Prvs-MHL")

// 周期判断：当前K线是否属于最新的日/周/月
is_current_day = ta.time >= ta.time("D")
is_current_week = ta.time >= ta.time("W")
is_current_month = ta.time >= ta.time("M")

// Daily
ph = request.security(syminfo.tickerid, "D", high)
pl = request.security(syminfo.tickerid, "D", low)

// Weekly
wph = request.security(syminfo.tickerid, "W", high)
wpdh = request.security(syminfo.tickerid, "W", high[1])
wpl = request.security(syminfo.tickerid, "W", low)
wpdl = request.security(syminfo.tickerid, "W", low[1])

// Monthly

mpdh = request.security(syminfo.tickerid, "M", high[1])
mpl = request.security(syminfo.tickerid, "M", low)
mpdl = request.security(syminfo.tickerid, "M", low[1])

// Daily Plots：仅在当前交易日显示
plot(st and is_current_day ? ph : na, title="TH", style=plot.style_line, linewidth=2, color=yellow_color)
plot(st and is_current_day ? pl : na, title="TL", style=plot.style_line, linewidth=2, color=yellow_color)

//Weekly Plots：仅在当前交易周显示
plot(swt and is_current_week ? wph : na, title="WH", style=plot.style_line, linewidth=3, color=yellow_color)
plot(swy and not is_current_week ? wpdh : na, title="Prvs-WH", style=plot.style_line, linewidth=3, color=yellow_color)
plot(swt and is_current_week ? wpl : na, title="WL", style=plot.style_line, linewidth=3, color=yellow_color)
plot(swy and not is_current_week ? wpdl : na, title="Prvs-WL", style=plot.style_line, linewidth=3, color=yellow_color)

//Monthly Plots：仅在当前交易月显示
plot(smh and is_current_month ? mph : na, title="MH", style=plot.style_line, linewidth=4, color=yellow_color)
plot(spmh and not is_current_month ? mpdh : na, title="Prvs-MH", style=plot.style_line, linewidth=4, color=yellow_color)
plot(smh and is_current_month ? mpl : na, title="ML", style=plot.style_line, linewidth=4, color=yellow_color)
plot(spmh and not is_current_month ? mpdl : na, title="Prvs-ML", style=plot.style_line, linewidth=4, color=yellow_color)

关键改动说明 #

• 新增周期判断逻辑：通过ta.time >= ta.time("周期标识")判断当前K线是否属于目标周期（当日/当周/当月），确保高低线仅在对应周期的K线区间内显示
• 调整plot显示条件：移除原代码中错误的颜色判断逻辑，替换为周期判断条件，非目标周期区间直接返回na，避免线延伸到历史K线
• 适配历史周期（上周/上月）显示：针对“Prvs-WHL”“Prvs-MHL”选项，添加反向周期判断，确保历史周期的高低线仅在对应历史区间显示，不会干扰当前周期
