How do I know when a new bar is being drawn???

Hi Alistair

Time[0] is the time the current bar started, so I use a variable to record the time a new bar appears and check it against Time[0], which will update when a new bar appears.

For example,

datetime ThisBarTime;                  // the time of the current bar

int init()
{
   ThisBarTime = Time[0];   // or ThisBarTime = Time[1]; to suit your purpose
}

int start()
{
   //----------------------------------------------------------------------------------------------
   // New bar checks
   if( ThisBarTime != Time[0] ) {  // if it's a new bar
      ThisBarTime = Time[0];

      // stuff to do when it's a new bar...
   }

   // more stuff...
}

Hwi!

with iBars() you have the number of bars (or candles) so if iBars() increases you are on a new candle. Then effectively, you can use iClose with the appropriate shift to compare with your indicator based on that same shift.
