[amibroker] Re: Sell after n bars only if net loss

["Pete" <dryheat3@xxxxxxx>]

EDIT:
In the reply below the last paragraph contains two errors.:
Quote:**************************************************************
The negative 5's above read the close of the bar 5 steps before the
close <<Buyprice>>. In order to read 5 bars after the close
<<BuyPrice>> you have to change the negatives to positives and this
gives a warning that the formula has to look into the future to
calculate trades.
End Quote:**********************************************************
