Its 
all a matter of "first come first serve".

This 
probably will change sometime in the future when TJ implements "portfolio 
trading".  Hopefully he will include multiple positions per symbol which 
would then give you the opportunity to really get complicated in your testing.

   Thank you for your prompt 
  reply.
   
  I feared that was the case from reading 
  the documentation.  It appears that some buy signals
  are deemed more important than 
  others.  I guess I must trust that, over the long haul, the 
  reported trades will adequately represent 
  the missing ones also.  I don't have to like it; but,
  I'll deal with it.
   
  Regards,
   
  Tony

  No 
  you won't see that. It only takes one position and while in that position 
  ignores any successive entry signal until it exits that 
  position.

    Backtesting
    Hello,
     
    I have a question on the backtest function.
     
    Suppose we are testing stock XXX.
    Our trading rules are:
            Buy = 
    condition1
            Sell = 
    condition2
     
    On 10/1/02, XXX meets condition1, establishing 
    Position A
    On 11/1/02, XXX meets condition1, establishing 
    Position B
    On 12/1/02, XXX meets condition2, at the price of 
    P.
     
    On 12/1/02, are two trades, A & B, shown on 
    the backtest report, both
    closed out at price P?
     
    In a number of tests, I have yet to see this 
    occur.
     
    Regards,
