I need help to figure out how to close all my positions.

[Jonathan Durance]

      string symbol = Symbol();
      ulong deviation = ULONG_MAX;
      if (PositionClose(symbol, deviation){
         Print("Position for symbol ", symbol, " closed successfully");
      }else{
         Print("Error closing position for symbol ", symbol, ". Error code:", GetLastError());
      }

I am trying to write code so that I can close my positions when a certain signal appears on the charts. I have been trying this for a long time but I cannot figure out how to solve this. This is what I have so far but I keep getting errors saying that there is some operator expected in 'symbol' and that ruins the third line of the code and leads to a few other areas in that line.

You can just search codebase.

Yashar is right, check the code base and furthermore you can always check youtube there are plenty of videos on that topic.
