The UNDEFINED keyword; how disable an indicator?

  Hi, just started on ProBuilder.

  I am creating a notional new indicator as follows: –

  if IntradayBarIndex > 109 AND IntradayBarIndex < (16 * 12) + 3 THEN atrupper = High + 2 ELSE atrupper = Undefined ENDIF

  1 2 3 4 5

  if IntradayBarIndex > 109 AND IntradayBarIndex < (16 * 12) + 3 THEN atrupper = High + 2 ELSE atrupper = Undefined ENDIF

  and would like to switch the indicator off on the charts overnight.  I had thought the keyword ‘UnDefined’ would do this, but it does not appear to work; it simply holds the indicator constant without stopping it from displaying.

  Any help greatly appreciated

  Once a variable has been defined it is not possible to return it to undefined status.

  You could try changing the contrast to zero in the COLOURED instruction.

  once atrupper = Undefined if IntradayBarIndex > 109 AND IntradayBarIndex < (16 * 12) + 3 THEN atrupper = High + 2 c = 255 ELSE c = 0 ENDIF return atrupper coloured(128,0,0,c)

  1 2 3 4 5 6 7 8 9 10

  once atrupper = Undefined   if IntradayBarIndex > 109 AND IntradayBarIndex < (16 * 12) + 3 THEN atrupper = High + 2 c = 255 ELSE c = 0 ENDIF   return atrupper coloured(128,0,0,c)
