Pine 中的条形图下方或上方不显示绘制的箭头
Plotted arrows aren't displayed below or above bar graph in Pine
我有下一个代码。

hist = macd - signal
plot(hist, title="Histogram", style=plot.style_columns, color=(hist>=0 ? (hist[1] < hist ? col_grow_above : col_fall_above) : (hist[1] < hist ? col_grow_below : col_fall_below) ), transp=0 )

timetobuy = buy==1
timetosell = sell==1
tup = barssince(timetobuy[1])
tdn = barssince(timetosell[1])
long = tup>tdn?1:na
short = tdn>tup?1:na
plotshape(long==1?buy:na, color=#26A69A, location=location.abovebar, style=shape.arrowup, title="Buy Arrow", transp=0)
plotshape(short==1?sell:na, color=#EF5350, location=location.belowbar, style=shape.arrowdown, title="Sell Arrow", transp=0)
如您所见，它是 macd 直方图代码和一些绘图代码，用于在直方图附近绘制箭头。我将它们的位置配置为上面和下面。但是，它们显示得离图表很远。
如何绘制 macdh 柱上方和下方的箭头？
通过使用 location=location.abovebar，该函数会影响交易品种的价格水平，这会破坏指标的比例。解决方案是使用 location=location.top 代替：
plotshape(long==1?buy:na, color=#26A69A, location=location.top, style=shape.arrowup, title="Buy Arrow", transp=0)
plotshape(short==1?sell:na, color=#EF5350, location=location.bottom, style=shape.arrowdown, title="Sell Arrow", transp=0)
