Dear Prashanth,
Thanks for your reply.
If that were the case, there was no need for programmer to include the following words for "Ref" in "Trading System Toolbox" of the "User's Guide".
REF - reference past/future values of the array
FUNCTION - References a previous or subsequent element in a ARRAY. A positive period references "n" periods in the future; a negative period references "n" periods ago.
EXAMPLE - The formula "ref( C, 12 )" returns the closing price 12 periods ahead (this means looking up the future)
If that were the case, he could have simply omitted these words.
I guess there still is some way in which one can get some data for periods ahead. Whether or not that data proves correct is not the issue. But is should be possible to return some positive values.
I request you please use your expertise and I hope you will have some solution to my problem.
Thanks.
