Fred,
there are two types of history : Static and dynamic.
The static has a very poor and nebulous logic : Cycles, repetition, 
destiny. I never use this type.
The dynamic is a bit painful, it reconsiders the situation everyday 
and has no basic assumptions. It fits well with trends and this is my 
main target. Thatīs why you frequently see my codes try to catch the 
trend, or, much better, anticipate it.
In this way of thinking, 98-99 days do not exist at all.
Perhaps your point of view is totally different, but this is an 
advantage for the dialogue.
As for the market, we are in a congestive phase, the violent decline 
of the first 9 months of 2000 has come to an end, I will wait 3 more 
months and I will erase 2000 from my data. I do not see any 
reflection of this period the last 6 months, so it is useless for my 
study and backtesting.

PS: I did not understand the comment for data providers. You may find 
data many years before 1998, if you wish. I simply donīt need them.
