考虑资金费率与库存风险的永续合约最优平仓 | Stratmill

文章 arXiv papers · 作者: Ryan Donnelly et al.

总结

本文研究交易者如何在平衡交易成本、库存风险和资金费用的同时平掉永续合约头寸。文中将平仓表述为随机控制问题,并在合约收益函数为标的价格的恒等函数时,推导出闭式最优交易策略。

对于非线性收益函数,本文针对资金费率参数较小或平仓期限较短的情形给出近似策略。文中还证明,短期限近似可以用恒等收益情形下的闭式策略表示。摘要介绍了理论推导,但没有提供市场数据、数值比较或实现细节,因此无法据此判断该策略在实盘交易或特定交易所资金费率规则下的表现。

核心观点

  • 平仓被表述为一个同时考虑交易成本、库存风险和资金费用的随机控制问题。
  • 文中为恒等收益函数推导了闭式最优策略。
  • 对于非线性收益,资金费率参数或平仓期限较小时可采用近似方法。
  • 非线性收益的短期平仓期限近似可通过恒等收益函数策略表示。

# Optimal Liquidation of Perpetual Contracts


# Optimal Liquidation of Perpetual Contracts









An agent holds a position in a perpetual contract with payoff function $ψ$ and attempts to liquidate the position while managing transaction costs, inventory risk, and funding rate payments. By solving the agent's stochastic control problem we obtain a closed-form expression for the optimal trading strategy when the payoff function is given by $ψ(s) = s$. When the payoff function is non-linear we provide approximations to the optimal strategy which apply when the funding rate parameter is small or when the length of the trading interval is small. We further prove that when $ψ$ is non-linear, the short time approximation can be written in terms of the closed-form trading strategy corresponding to the case of the identity payoff function.
