Re: [amibroker] moving av cross over advice please

Paul
The function you need to use is BarsSince as shown below. 
 
Run this as an Explore against a Filter = family or ALL, and N last quotations 
= 1 and you'll get all crosses that occurred over the 
last ten bars.  

// Filter= EMA(C,5) Cross EMA(C,10) within last 10 periods;

Cond1 = Cross(EMA(C,5),EMA(C,10)); 

Cond2 = BarsSince(Cond1); 

Filter = Cond2 <= 10 AND Cond2>0; 

AddColumn(Cond1,"Cross"); 

AddColumn(Cond2,"Bars Since Cross"); 

AddColumn(Filter,"Filter"); 

OR SET the filter as 

Filter = Cond2 <= 10 AND Cond2>0 AND Status("LastBarinRange"); 

AND THE SCRIPT WILL BE A LITTLE MORE FORGIVING AS TO WHERE YOU SET THE DATE 
RANGE

Hope this helps

  Subject: [amibroker] moving av cross over advice please


  Hi,
  i tried posting this via the yahoo web site but it never came 
  through so posting directly,,,,(just in case it doubles up)

  i'm trying to build an exploration that looks for 2 moving av's to have 
  crossed over within the last number of periods,,,i can build one for cross 
  over today but i'd like to build one that has crossed over "within" the last 
  number of periods.

  ie
  filter= ema(c,5) cross ema(c,10) within last 10 periods;

  any advice or direct help please,,,
  regards
  Paul
