将自定义 TA 添加到 chart.Posn()

Question

I have the same problem as: Add Technical Indicator to chart.Posn我有同样的问题：将技术指标添加到 chart.Posn

However, I am working with a custom indicator and it is plotting on top of the positions chart.但是，我正在使用自定义指标，它绘制在头寸图表的顶部。 can someone assist me?有人可以帮助我吗？ The indicator I am working with is proprietary, but any defined custom-indicator solution would be helpful.我正在使用的指标是专有的，但任何定义的自定义指标解决方案都会有所帮助。

Here is my chart.Posn() call:这是我的 chart.Posn() 调用：

chart.Posn(Portfolio = strategy, 
           Symbol = tickers, 
           theme = myTheme, 
           Dates = "2016-01-20::2016-01-20",
           TA = "add_TA(range_expansion_index(OHLC(mktdata)))")

and this is what my output looks like (i have highlighted the problem in the red box):这就是我的输出的样子（我在红框中突出显示了问题）：

Answer 1

the solution that worked for me was the add_TA function.对我有用的解决方案是 add_TA 函数。 for example,例如，

rei <- my_function(close_prices, period = 5) 

chart.Posn(Portfolio = strategy_nm, 
           Symbol = tickers, 
           theme = myTheme)

add_TA(rei, col = "black", lwd = 1.5, legend = "REI", type = 'l')
