Hi, I have been trying to code the standard deviation for a VWAP indicator i found but it wasn't plotting the deviation bands, and someone in my previous post said if I understood the code and they were right, so I decided to write a VWAP indicator

Hello Im a beginner at MQL5, so im trying to add the first deviation bands to a VWAP indicator code I found, but is not plotting on the chart, i am missing something?  //+------------------------------------------------------------------+

 I'm new at learning to code, so im trying to add the standard deviation bands, to a VWAP indicator code I found on the Internet but I get the "FirstDevDaily" undeclared identifier error and dont know how to fix it. //--- Standard Deviations
