Hi,<br><br>I am trying to learn how to create customized indicator. Mostly I have my own recipe which TTR does not cover. I only know that the indicator function is supposed to return xts. But I couldn't get it to work on my example. I attached the file here. The customized indicator function is called "devCalc" which calculates deviation between current price and a given VWAP. Then normalized with volatility. I named the indicator as "dev" in add.indicator's label. R complains that no "dev" found when I try to use it to define my signal. Any help would be appreciated. Thank you.<br>
