關於更改 macd 線條顏色的 tradingview 松腳本

Question

對不起，我是代碼初學者

我想改變我的 macdline 顏色

當新的 macdline 比上一個 macdlie 高時

短的話會顯示綠色，會顯示紅色，

我的原始代碼：

 indicator(title="Moving Average Convergence Divergence", shorttitle="MACD", timeframe="", timeframe_gaps=true) fast_length = input(title="Fast Length", defval=12) slow_length = input(title="Slow Length", defval=26) src = input(title="Source", defval=close) signal_length = input.int(title="Signal Smoothing", minval = 1, maxval = 50, defval = 9) sma_source = input.string(title="Oscillator MA Type", defval="EMA", options=["SMA", "EMA"]) sma_signal = input.string(title="Signal Line MA Type", defval="EMA", options=["SMA", "EMA"]) macdline = fast_length - slow_length macdlinecolor = if macdline[0] > macdline[1] macdlinecolor = color.green else macdlinecolor = color.red col_macd = input(#2962FF, "MACD Line  ", group="Color Settings", inline="MACD") col_signal = input(#FF6D00, "Signal Line  ", group="Color Settings", inline="Signal") col_grow_above = input(#26A69A, "Above   Grow", group="Histogram", inline="Above") col_fall_above = input(#B2DFDB, "Fall", group="Histogram", inline="Above") col_grow_below = input(#FFCDD2, "Below Grow", group="Histogram", inline="Below") col_fall_below = input(#FF5252, "Fall", group="Histogram", inline="Below") fast_ma = sma_source == "SMA" ? ta.sma(src, fast_length) : ta.ema(src, fast_length) slow_ma = sma_source == "SMA" ? ta.sma(src, slow_length) : ta.ema(src, slow_length) macd = fast_ma - slow_ma signal = sma_signal == "SMA" ? ta.sma(macd, signal_length) : ta.ema(macd, signal_length) hist = macd - signal hline(0, "Zero Line", color=color.new(#787B86, 50)) 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))) plot(macd, title="MACD", color=macdlinecolor) plot(signal, title="Signal", color=col_signal)

但它錯了，我該如何修復我的代碼？ 請QQ

您已經根據 macd 長度計算了顏色。 您將不得不使用實際的 macd 來計算它。 下面的例子

//@version=5
indicator(title="Moving Average Convergence Divergence", shorttitle="MACD", timeframe="", timeframe_gaps=true)

fast_length = input(title="Fast Length", defval=12)
slow_length = input(title="Slow Length", defval=26)
src = input(title="Source", defval=close)
signal_length = input.int(title="Signal Smoothing",  minval = 1, maxval = 50, defval = 9)
sma_source = input.string(title="Oscillator MA Type",  defval="EMA", options=["SMA", "EMA"])
sma_signal = input.string(title="Signal Line MA Type", defval="EMA", options=["SMA", "EMA"])

macdline = fast_length - slow_length



col_macd = input(#2962FF, "MACD Line  ", group="Color Settings", inline="MACD")
col_signal = input(#FF6D00, "Signal Line  ", group="Color Settings", inline="Signal")
col_grow_above = input(#26A69A, "Above   Grow", group="Histogram", inline="Above")
col_fall_above = input(#B2DFDB, "Fall", group="Histogram", inline="Above")
col_grow_below = input(#FFCDD2, "Below Grow", group="Histogram", inline="Below")
col_fall_below = input(#FF5252, "Fall", group="Histogram", inline="Below")

fast_ma = sma_source == "SMA" ? ta.sma(src, fast_length) : ta.ema(src, fast_length)
slow_ma = sma_source == "SMA" ? ta.sma(src, slow_length) : ta.ema(src, slow_length)
macd = fast_ma - slow_ma
macdlinecolor =  macd[0] > macd[1] ? color.green : color.red
signal = sma_signal == "SMA" ? ta.sma(macd, signal_length) : ta.ema(macd, signal_length)
hist = macd - signal
hline(0, "Zero Line", color=color.new(#787B86, 50))
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)))
plot(macd, title="MACD", color=macdlinecolor)
plot(signal, title="Signal", color=col_signal)
