Hi mdimen,
Welcome to the Forum.
MetaStock uses "single digit precision" so it loses accuracy above 7 or 8 significant digits (the jury is debating the exact level!). Although MS is capable of charting much larger values, the scale will only show a "few" significant digits and an exponent multiplier.
Some argue, the larger the number the less significant the smaller components, so often data providers round volume (for example) by dividing the real value by, say, 1,000 i.e. a volume of 1,000,000 is displayed with a value of 1,000.
From memory, MS creates an overflow error at 2^128 (or approx 3.4028E38 according to my calculator)
Hope this helps.
