On a scale. A term used in speculative operations in stocks, meaning buying or selling, as the
case may be, at stated intervals in prices as prices decline or advance. For instance, buying at
100, 98, 96, 94 and 92 would be buying on a 2 per cent declining scale. Reversing the order of
prices would be buying on an ascending scale. The operation of selling on a scale is conducted in
the same fashion.  Also see Pyramiding.
