Yuki,
even with missing bars, you may avoid composite errors if you
calculate Mean quantities:
Run with your composite tickers the
AddToComposite(1,"~count","v");
and remember to divide your final quantity by the population, ie the
Foreign("~count","v");
If a bar is missing from stock XXX, its indicator value will not be
added, but the count will be reduced by 1 unit and you will avoid the
undesirable spikes.
