如何将拼音第2版转换为第5版？

Question

我发现这个代码由图表艺术，我只需要快速颜色变量从这个。我正在建立我自己的战略，我会喜欢在我的这个功能。它为我的进入信号提供了更好的确认。我真的很感谢你的帮助。先谢谢大家。

//@version=2    
// Input
fastlen = input(12, title="Fast Moving Average")
slowlen = input(26, title="Slow Moving Average")
signallen = input(9, title="Signal Line")
switch1=input(true, title="Enable Bar Color?")
switch2=input(true, title="Enable Moving Averages?")
switch3=input(true, title="Enable Heatmap?")

// Calculation
fast = ema(close,fastlen)
slow = ema(close,slowlen)
MACD = fast - slow
signal = ema(MACD, signallen)
histogr = MACD - signal

// MACD, MA colors
MACDcolor = fast > slow ? green : red
fastcolor = change(fast) > 0 ? green : red
slowcolor = change(slow) > 0 ? green : red
MACDupdowncolor = change(MACD) > 0 ? green : red

错误：

Could not find function or function reference 'ema'.

这是将您的代码片段转换为v5，但是您的脚本是不完整的，因为没有输出(没有情节)。我加了一个。

//@version=5
indicator("My Script", overlay=false)

// Input
fastlen = input(12, title="Fast Moving Average")
slowlen = input(26, title="Slow Moving Average")
signallen = input(9, title="Signal Line")
switch1=input(true, title="Enable Bar Color?")
switch2=input(true, title="Enable Moving Averages?")
switch3=input(true, title="Enable Heatmap?")

// Calculation
fast = ta.ema(close,fastlen)
slow = ta.ema(close,slowlen)
MACD = fast - slow
signal = ta.ema(MACD, signallen)
histogr = MACD - signal

// MACD, MA colors
MACDcolor = fast > slow ? color.green : color.red
fastcolor = ta.change(fast) > 0 ? color.green : color.red
slowcolor = ta.change(slow) > 0 ? color.green : color.red
MACDupdowncolor = ta.change(MACD) > 0 ? color.green : color.red

plot(MACD, color=MACDcolor, style=plot.style_histogram)
