RE: [amibroker] Question re MA

["Bob Jagow" <bjagow@xxxxxxxxxxx>]

For your 15 day SMA, the 
cross is at C = MA = (15*MA0 -MA1st + C)/15, where 0 is yesterdays 
value.
<FONT 
color=#000080>Therefore 
15*MA = 15*MA0 -MA1st + 
MA 
MA =  (15*MA0 
-MA1st)/14
Might try the EMA also; 
it crosses when C = EMA0.

  Question re MA
  
  <FONT face=Arial color=#0000ff 
  size=2>Hi,
  Does anyone know how I can 
  predict a trend change.  I want to know what value will make a MA go 
  positive tomorrow. 
   
  <FONT face=Arial color=#0000ff 
  size=2>If I take the MA for the past 15 days and subtract the MA for one day 
  back from the 15 days then if it's positive I am saying that the trend is 
  up.
  <FONT face=Arial color=#0000ff 
  size=2> 
  How 
  can I determine the value that will make it go negative?
