I am trying to learn loops by using the example below from the help
files. The sell price when the profit stop is hit should be defined
by the line:
SellPrice[ i ] = Max( Open[ i ], ( 1 + firstProfitTarget * 0.01 ) *
priceatbuy );
Instead of this, the close for the day is the sell price. Why? I am
using Yahoo data with OHLC.
Thanks in advance
Larry
