RE: [amibroker] String Logic Check

["Graham" <gkavanagh@xxxxxxxxxxxxx>]

Only guessing, but you are 
telling it to write a blank "" if the condition is 
false
Do you mean an exploration 
rather than Scan? If an exploration then maybe Filter=Buy; might help remove the 
blanks you don't want.

  Check
  Am I correct in 
  the use of this?
  <FONT face=Arial

  mvSignal = "Now 
  looks like a good time";
  
  myAlert = WriteIf((<FONT 
  color=#0000ff>LastValue(Buy) ==<FONT 
  color=#ff00ff>1),mvSignal ,<FONT 
  color=#ff00ff>"");  //This didn't 
  work as I wanted
  <FONT

  <FONT face=Arial color=#0000ff

  condition only?  ...not either text or blank <FONT

  2) 
  <FONT 
   color=#ffffff>addtextcolumn( string, 
  name, format = 1.2, textColor = colorDefault, 
  bkgndColor = colorDefault ) How do use format when it is a 
  string, just leave it out, or ???<FONT

  it?
  <FONT

  this?
  Thanks 
  in advance.
