摘要翻译:
本文继续研究具有连续价格过程的理想化金融市场中出现的随机性类型的性质。在不作任何概率假设的情况下,证明了非定常价格过程的强变分指数必须为2,就像连续鞅的情形一样。

英文摘要:
This note continues investigation of randomness-type properties emerging in idealized financial markets with continuous price processes. It is shown, without making any probabilistic assumptions, that the strong variation exponent of non-constant price processes has to be 2, as in the case of continuous martingales.
