[amibroker] First Value When

["Ken Close" <ken45140@xxxxxxxxx>]

I want to determine the stock price (to become the Buyprice) at the very
first Buy signal in a series of buy signals over a range.
 
When I have written 
 
ValueWhen(Buy, Close);
 
I get changing buy prices at each Buy signal.
 
I have tried counting the number of Buy signals in the Range, and using
 
ValueWhen(Buy, Close, NumbBuys);  but that does not seem to get it.
 
What I am doing is using the BuyPrice to determine the number of shares
purchased at that very first buy signal, then wanting to maintain that same
number of shares throughout the range.
 
Any suggestions to solve my problem?
 
Thanks,
 
Ken
