In order to be able to process $NDX prices higher than 1638.0 correctly, you can use the file REDUCE -- described in detail in the February 1997 newsletter -- which is designed to allow users to correct prices when they go over 1638.
The file called REDUCE contains the offsets to use for any symbol you want. It is a small text file and you can modify it with any text editor or word processor. DollarLink reads this file at startup. If it finds a line in the form
ABCD,NN.N
then DollarLink knows to offset all prices for the symbol ABCD by the amount NN.N.
If the file REDUCE is not in the DollarLink directory, then DollarLink works as before this upgrade.
We supply this REDUCE file with the new updates and it contains three lines
SP_,500.0 WP_,500.0 ND_,500.0to take care of the S&P (day and night sessions) and NDX futures.
To add the correction for $NDX, just add the following line at the end of the REDUCE file:
$NDX,500.0This will offset the $NDX internal prices by 500.0.
Please review our newsletter for February 1997 for further details on REDUCE and its effect on historical data.
