Tomasz,
Since we can not work with YYYYMMDD format, the solution is to change 
to DD/MM/YYYY, it is equally recognised from the import wizard and it 
is automatically available in the AA result list.
I suppose now that the missing data repair is finished, using the 
convention to put the last existing OHLCV in the hole[s].
Do you have any plans for hole detection/repairing solution ?
I see many people unhappy when the first composite taste is bitter, 
because of their missing data.

floating-point number represent approximately 7 significant decimal 
digits. Unlike the real number system, which is continuous, a 
floating-point system has gaps between each number. If a number is 
not exactly representable, then it must be approximated by one of the 
nearest representable values.
