[amibroker] Closing for Following dday

[M. Dawson]

Ok so the system I have has a price of 17.10 on closing on day 0.  Now I want 
that same price the following day.  But day 1 price opens at 18 dollars but 
dips to 16.90.  The system takes the 16.90 number.  How do you force the limit 
price to 17.10 on end of day info.  If it did not come across this number of 
17.10 and only went to 17.20, how do you force it to not make the trade.  Kind 
of stuck with bad backtesting.
