I wrote a script to populate my database with the 'missing' (well, not
really missing) quotes for the indexes.
As this is a workaround for the above problem, I don't think it is the
way it should work ...
I'm thinking about hacking EMA and SMA for this ... is this the place
where it should be modified ? I can think also about changing
Indicators::Prices or even DB.pm ... ? What's the best place ?
