Pine script Pinescript未在较低的时间段图表上绘制更高分辨率的计算。如何解决

我已经创建了一个基于较高时间段的绘图，以便在较低时间段查看。然而，当我切换到较低的时间段时，没有进行绘图，代码中会出现什么错误

tflow   = security(syminfo.tickerid,expression = low, resolution = i_resolution, gaps = barmerge.gaps_off, lookahead = barmerge.lookahead_on )

highValue       := tfhigh < highValue[1] and tflow > lowValue[1] ? highValue[1] : tfhigh
lowValue        := tfhigh < highValue[1] and tflow > lowValue[1] ? lowValue[1] : tflow

// Define Bar Types
barType         := highValue > highValue[1] and lowValue > lowValue[1] ? "Up" : highValue < highValue[1] and lowValue < lowValue[1] ? "Down" : highValue > highValue[1] and lowValue < lowValue[1] ? "Out" : "In"

// Generate bias
bias            := barType == "Up" ? highValue : barType == "Down" ? lowValue : barType == "Out" and barType[1] == "Up" ? highValue : barType == "Out" and barType[1] == "Down" ? lowValue : bias[1]

// Bias shift to bullish or bearish
bullishcondition = bias > bias[1] and bias[1] < bias[2]
bearishcondition = bias < bias[1] and bias[1] > bias[2]

// Values to plot
upBias = valuewhen(bullishcondition, bias[1],0)
dnBias = valuewhen(bearishcondition, bias[1],0)
plot(upBias, color = color.green)
plot(dnBias, color = color.red)

//_____________计算
//为偏差计算指定高-低
tfhigh=security（syminfo.tickerid，expression=high，resolution=i\u resolution，gaps=barmerge.gaps\u off，lookahead=barmerge.lookahead\u on）
tflow=security（syminfo.tickerid，expression=low，resolution=i\u resolution，gaps=barmerge.gaps\u off，lookahead=barmerge.lookahead\u on）
高值：=tfhigh<高值[1]和tflow>低值[1]？高值[1]：tfhigh
低值：=tfhigh<高值[1]和tflow>低值[1]？低值[1]：tflow
//定义条形图类型
barType:=高值>高值[1]和低值>低值[1]？“向上”：高值<高值[1]和低值<低值[1]？“向下”：高值>高值[1]和低值<低值[1]？“向外”：“向内”
//产生偏见
偏差：barType==“向上”？高值：barType==“向下”？低值：barType==“向外”和barType[1]==“向上”？高值：barType==“向外”和barType[1]==“向下”？低值：偏差[1]
//偏向转向看涨或看跌
看涨条件=偏差>偏差[1]和偏差[1]<偏差[2]
bearishcondition=偏差<偏差[1]和偏差[1]>偏差[2]
//要绘制的值
upBias=valuewhen（看涨条件，偏差[1]，0）
dnBias=valuewhen（熊市条件，偏差[1]，0）
绘图（上视，颜色=颜色。绿色）
绘图（dnBias，颜色=颜色。红色）

因为这些条件总是错误的

bullishcondition = bias > bias[1] and bias[1] < bias[2]
bearishcondition = bias < bias[1] and bias[1] > bias[2]

问题在于较低的tf偏差与偏差1比较较低的tf值需要给出要与之比较的tf的倍数。С完成了答案。谢谢你解决了这个问题。我之前尝试过输入安全函数，但不知道偏差作为一个函数可以在安全中绘制。非常感谢
