对于在线学习(On-line Learning)对于 t 时刻,其梯度可以通过如下公式计算: \frac{dU_t(\theta)}{d\theta}=\frac{U_t}{dR_t}\left(\frac{dR_t}{dF_t}\frac{dF_t}{d\theta}+\frac{dR_t}{dF_{t-1}}\frac{dF_{t-1}}{d\theta}\right) 然后通过反向传播与梯度下降更新权重反复迭代最大化...
Can deep reinforcement learning be used to make automated trading better? Is reinforcement learning popularly used in trade execution optimization? Can reinforcement learning be used to forecast time series? PS:近两年由于深度学习的火爆,深度增强学习的出现将带来新的一波浪潮,听说美国已经有人用Deep Reinfor...
We propose to train trading systems and portfolios by optimizing financial objective functions via reinforcement learning. The performance functions that we consider as value functions are profit or wealth, the Sharpe ratio and our recently proposed differential Sharpe ratio for online learning. In Moody...
From the series:Machine Learning in Finance Algorithmic stock trading is now the norm rather than the exception with the majority of trades being automated. Deep reinforcement learning is a promising area of research with the potential to mimic the decision-making of traders with years of experience...

Reinforcement Learning (RL) is a cutting-edge AI technique, ideal for Algorithmic Trading, but often daunting for beginners. This course is tailored specifically for those new to RL, addressing common challenges like complexity, setup, and foundational knowledge.This course will guide you through the...
Reinforcement Learning for Trading 这篇文章是John moody 1997年(不太记得了)写的,算是RL做trading里面比较奠基的一篇文章,后面对这个模型有一些变体和改进,下次在叙。 其实我已经读过这篇文章三遍以上了,但是总是看懂了就放下,下次看到又忘了,看paper这种事,还是看一篇总结一篇好,这次算是把一些问题想明白了,...
论文: Hybrid Deep Reinforcement Learning for Pairs Trading1. 问题介绍配对交易是一种统计套利策略,利用具有高度相关资产对之间的短期价格差异进行获利。在股票市场上,成对交易者同时在估值过高的股票上做空…
The trained reinforcement learning agent is employed to trade the S&P500 ETF (SPY) data set. Findings show that this approach can encounter the best trading action to choose at a specific moment and outperforms the classical DQN (Deep QNetwork) method. 展开 关键词: Deep reinforcement learning...
