Walt,
 
thank you very much!!
I probably found some bugs in 
the indicator.Look at the pic I 
sent you ...the gap is closed and the blue lines show up.
 
I think 5 to 10 minutes is a 
balanced timeframe in regards to slippage, commisions, noise in indicators. 
Anyway, perhaps you can fine tune your entry with lower timeframe (ie, 1 
minute). My idea is to look for very high prob trades ( return expectancy 
>0) in a bunch of "range" and "trend" systems. They trade rarely. But if you 
combine the best ones...looks good. <FONT face=Batang color=#0000ff 
size=2>I finished a new system today, but i have to code it..... perhaps i would 
ask for more help.
What kind of systems do u 
develop.....trend , range or?? Any insights to share?
I used MS as my first soft, NOT good 
as I thought. There is no flexibility and the language is very tough. Amibroker 
is one of the best or the best. I never tried TS nor Ensign...have you? 
Wealthlab very difficult...and I 
think that's all there are no other well known soft.
 
 
Here;s what I was coding for 
gaps.....does not work....but perhaps it can be "fixed" easily.
 

x1 = IIf(<FONT 
color=#0000ff>GapUp(),1,<FONT 
color=#0000ff>IIf(GapDown(),-<FONT 
color=#ff00ff>1,0));
x2 = IIf(x1!=0,<FONT 
color=#0000ff>Date(),0);
x3 = IIf(<FONT 
color=#0000ff>TimeNum()=93000 AND 
x1!=0,<FONT 
color=#0000ff>Ref(High,-1),<FONT 
color=#0000ff>IIf(x2=Date(),<FONT 
color=#0000ff>Ref(x3,-1),<FONT 
color=#ff00ff>0);
x4= IIf(TimeNum()=<FONT 
color=#ff00ff>93000 AND x1!=0,<FONT 
color=#0000ff>Ref(Low,-1),<FONT 
color=#0000ff>IIf(x2=Date(),<FONT 
color=#0000ff>Ref(x4,-1),<FONT

Thanks

  Here 
  you are Juan;
  <FONT face=Arial color=#0000ff 
  size=2> 
  This 
  will show blue when there is a gap and green when gap is 
  resolved...
  It 
  will only work for intraday charts and you have to catch the last quote of the 
  previous day.
  <FONT face=Arial color=#0000ff

  BTW; 
  Why did you pick 10 minute intervals?

                [amibroker] Gaps
                hello,
                 
                    
                       1) I am trying to identify 
                gaps in my system. Why i can't   plot 
                "x"? 
                 
                
                IIf(<FONT 
                color=#0000ff>GapUp(),x=<FONT 
                color=#ff00ff>1,IIf(<FONT 
                color=#0000ff>GapDown(),x=-<FONT 
                color=#ff00ff>1,x=<FONT 
                color=#ff00ff>0));
                Plot(x,<FONT 
                color=#ff00ff>"Gaps",1,<FONT 
                color=#ff00ff>3);
                 
                2) is there any way to:
                    a) identify only 4:10PM to 
                9:30 AM gaps.
                    b) keep the gap true 
                value until it closes the gap. If during the day is not 
                close, change to false gap value.
                    Thanks
