I started once to decypher the ctree structure but was then
distracted to other subjects:
it starts:
Field, meaning, length, datatype
1, Symbolname,16, char
2,date in Omega format,2, 16bit integer
3,???,2,16bit integer
4,???,2,16bit integer
5,???,2,16bit integer
6,???,2,16bit integer <- could be the baseprice -first tick of day
the following fields should be always time and difference prices.
Note that integers could be either 0 to 64k or -32k to +32k
I suspect that the baseprice is in the former and the diff prices in
the later format.
in 3,4,5 should be somewhere the start time of the first tick.
Time should be minutes since midnight
Date is days since 1.1.1901 if I recall correctly.
A new record starts always on a new day.
Each record holds obviously only data for one symbol.
The easiest way to deciper is to get small history for one day, one
symbol in the server, print it out. Then go into datajunction find
the record and deciper.
Please post the results of your findings so that someone can build
some tool to correct bad ticks.
