Re: [amibroker] Which is faster ?

Thanks Herman, that's exactly what I needed. I 
expected that barindex based method will be faster but didn't expect it'll  
be over 10x.

  You 
  can easily check which is faster. Using some dummy parameters (I don't know 
  yours), on a 2.133 GHz Athlon, this is what I get 
  using DebugView:
  <FONT face=Arial color=#0000ff 
  size=2> 
  <FONT face=Arial color=#0000ff 
  size=2>was_buy=IIf<FONT 
  color=#000000>(when_buy < when_sell AND data_buy==data_sell 
  AND data="">1<FONT 
  color=#000000>,0<FONT 
  color=#000000>);                                    
  //    337 
  microSeconds
  was_buy=<FONT 
  color=#0000ff>IIf(BarsSince(Buy1) > <FONT 
  color=#0000ff>BarsSince(Sell1) AND data_buy==data_sell 
  AND data="" color=#ff00ff>1,<FONT 
  color=#ff00ff>0);    // 4930 
  microSeconds
   
  <IMG alt="" hspace=0 
  src="jpg00062.jpg" align=baseline 
  border=0>
  <FONT face=Arial color=#0000ff 
  size=2> 
  This 
  shows that if your programs execute slow and take minutes or 
  even hours to complete you should try some code-optimizations, I 
  couldn't do without DebugView anymore. I added a menu item in the Custom 
  Tools menu in AB, that way it is only a click away.
