Re: [amibroker] Help with formula

["Al Venosa" <advenosa@xxxxxxxxxxxx>]

Jason and Henry:
 
Chuck LeBeau suggests buying when the ADX(18) (he likes 18 days as the 
period) falls below 15 or 20 (end of the former trend, price in 
consolidation), then upticks relative to yesterday (beginning of the new trend) 
while the PDI(18) is above the MDI(18). Opposite for short. So, that would 
be:
 
n1=Optimize("n1",15,12,20,1); //number that ADX must be less than
n2=Optimize("n2",18,10,22,1); //period of ADX, PDI, and MDI
n3=Optimize("n3",0.4,0.1,1,0.1); //fraction of uptick move
Cond1=PDI(n2)>MDI(n2) and ADX(n2) < n1 AND ADX(n2) > 
n3*ref(ADX(n2),-1);
Buy=ref(Cond1, -1);
 
If you prefer using Cross, you can modify Cond1 to:

Cond1=PDI(n2)>MDI(n2) and ADX(n2) < n1 AND Cross(ADX(n2), 
n3*ref(ADX(n2),-1));
 
I think I'd prefer the first Cond1, but it might not make much difference.

  I 
  think you would string the conditions together with cross and 
  AND

  Help with formulaHi guys,ADX 
  SYSTEMI'm using the directional system to identify a new major trend. 
  E.g. when ADX(14) rises from below the two directional lines and crosses 
  -Dl(14) and +Dl(14) is above -D(14), a new uptrend is likely to start. 
  Can anyone help with the formula for amibroker to explore and set 
  alert ?Also an exploration to pick / alert stock with NEW HIGH IN 
  LAST X DAY ?thanks in advance
