All I did was copy the code from the messages here 
and put it into amibroker.  No changes were made to the code, as soon as I 
hit apply I would get the syntax error message.  I highlighted in red on 
the code on this page where there errors occurred.

  Re: [amibroker] Re: Search Routine for Crossover Point -- EMA

  I tried running the code here as it looks like 
  something that I've been searching for for a while.  When I tried to run 
  it I keep getting syntax error 23 whenever the words calc or goal come 
  up.  Could someone explain to me how to go about fixing this?  The 
  specific areas where this occurs are Calc=P1; and <FONT face="Courier New" 
  size=3>Goal = LastValue(BBandBot(P1, 14, 2)); 
  Thank you,
  Ron

    <FONT face=Arial 
    color=#0000ff size=2>Take a closer look at what Fred did.  He shifted 
    the array back by 1 bar so that it would plot into the 
    future by one bar. It just doesn't use the space that is non-addressable in 
    the chart area.  Its the only solution right now and it can be adapted 
    to  what you want by shifting the array by as many bars as you 
    need.

    Gentlemen,
     
    This is starting to get interesting especially 
    of someone can figure out how we can extend this into the whitespace area 
    beyond the latest data.
     
    For example, use your favourite indicator(s) 
    and apply projected regression channel to the prices.  
     
    Qu: A.what happens to your indicator when 
    prices are at the mid and extremes of the next bar..and the next bar, then 
    
     
    B. use the formula below to see what happens 
    when the indicator is 1. extrapolated , 2. the same or 3. (2*same - 
    extrapolated)
     
    What would be interesting is what happens to 
    all the indicators and the prices in the channel when this is applied to one 
    indicator, and how the indicators look in different time frames.  
    What does it mean to the setting of stops and exits philosophy is also 
    an interesting outcome.
     
    Any comments?
     
    Peter

      Is there any reason to limit this to an xMA when this 
      can easily be done for any built in AB indicator or any custom AFL
