<FONT
color=#0000ff>In the Portfolio Settings page we can select "Pad and Align data
to Reference symbol". The help says: "Auto Analysis/Settings,
portfolio backtester (both regular and rotational modes): added ability to pad
and align all symbols to reference symbol. Note: by default this setting is
OFF. Use responsibly. It may slow down backtest and introduce some slight
changes to indicator values when your data has holes and holes are filled with
previous bar data. The feature is intended to be used ONLY when your system
uses general market timing (generates global signals based on data and/or
indicators calculated using Foreign from 'reference' symbol). Note 2: if
reference symbol does not exist, data won't be padded."

Can
someboy explain this in lay-man's terms? I think it means that any stocks that
have less data than the Reference symbol will be padded to provide a data array
of reference length... but if this is the case "what" is the array padded with?
Or is the Reference array padded to the length of the largest stock
array?

When
do I use it?
Why is
it needed?
What
goes or can go wrong if I don't use it?

Many
thanks for any help you can give!
