一种瞬时市场波动率估计方法

An instantaneous market volatility estimation

Oleh Danyliv, Bruce Bland

摘要:

通过研究算法交易的不同方面,我们从经验上发现了一个新的市场不变量。它将该工具的波动性与其交易量、平均点差和订单簿中的交易量联系在一起。该不变量已在不同市场和不同资产类别上进行了测试。在所有情况下,我们没有发现重大违反的不变量。不变量的公式用于波动率的估计,我们称之为瞬时波动率。定量比较表明,它再现了实现波动率比一天前的Gestival(1,1)预测。由于短期预测的性质,瞬时波动率可以被算法开发人员,波动率交易员和其他市场专业人士使用。

英文摘要:

Working on different aspects of algorithmic trading we empirically discovered a new market invariant. It links together the volatility of the instrument with its traded volume, the average spread and the volume in the order book. The invariant has been tested on different markets and different asset classes. In all cases we did not find significant violation of the invariant. The formula for the invariant was used for the volatility estimation, which we called the instantaneous volatility. Quantitative comparison showed that it reproduces realised volatility better than one-day-ahead GARCH(1,1) prediction. Because of the short-term prediction nature, the instantaneous volatility could be used by algo developers, volatility traders and other market professionals.
