The pith

A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.

The reading

This doctoral thesis sets out to show that reinforcement learning can do the full market-making job: post competitive bid and ask prices, control inventory risk, and keep adapting when the market changes. It claims that a deep Q-learning agent quoting buy, sell, and hedge actions from a discrete grid learns to profit in a simulated market where it competes with random and persistent market makers. To control inventory, the thesis introduces two mechanisms: a reward-engineering penalty with an alpha/timing coefficient pair, and a multi-objective RL agent that keeps profit and inventory as separate objectives and optimizes a Pareto front. To handle market drift, a discounted Thompson-sampling combiner (POW-dTS) weights pretrained policies online. If the claims hold, the practical consequence is a parameter-light recipe for building adaptive, inventory-aware market-making agents.

What carries the argument

The machinery is a deep Q-network with a discretized three-lever action space: at each step the agent chooses a buy-spread multiplier, a sell-spread multiplier, and a hedging fraction over a fixed grid. The thesis wraps this agent in three progressively stronger controllers: a reward term that penalizes inventory outside a dynamic threshold set by cash and recent mid-price; a multi-objective version with two independent DQN blocks whose weighted Q-values are used for action selection and whose undominated policies form a Pareto front; and a policy-weighting layer (POW-dTS) that draws a policy from a pretrained library according to discounted Thompson sampling, so the active policy mixture follows changing market conditions. The mechanism carries the argument by making the learning objective explicit and tunable: a higher alpha means stricter inventory control, the utility weight chooses a point on the Pareto front, and the Thompson-sampling discount favors policies that have earned recent reward.

What would settle it

Run the trained policies in a simulator variant where investor orders are split stochastically among market makers, or where a small transaction fee is charged, and measure average end-of-session mark-to-market; the central claim fails if the RL agents no longer beat the random and persistent baselines in that setting.

Core claim

The central claim is that a DQN-based market maker operating in a simulated order-book market can learn to out-trade simple baselines: in single-agent and multi-agent competitions, the learned agent ends with positive average mark-to-market while random and persistent agents end negative. The thesis further claims that inventory can be managed without sacrificing profitability by making the penalty dynamic; two coefficients, the Alpha Inventory Impact Factor and the Dynamic Inventory Threshold Factor, set a time-varying inventory threshold based on cash and recent mid-prices. The M3ORL variant replaces the scalar reward with two Q-networks, one for mark-to-market and one for inventory, selected via a utility weight, producing a Pareto front of undominated policies and beating the reward-engineered version on multi-objective metrics. Finally, POW-dTS, which combines pretrained policies with discounted Thompson sampling, is claimed to outperform single-policy retraining and continual-learning baselines in non-stationary market scenarios.

Load-bearing premise

The load-bearing premise is that investor orders always match the market maker with the narrowest spread and that trades carry zero fees; if real order routing is less price-focused or fees matter, the learned policies' edge in the simulated tournament may not transfer.

Editorial extensions

If this is right

  • A sweep over the inventory-penalty coefficient AIIF yields a family of market makers with different risk profiles, so an operator can select the desired spread aggressiveness without retraining from scratch.
  • Because the multi-objective agent stores each objective in its own Q-network, the learned value estimates remain usable when the operator later changes the trade-off weight, letting one training run serve many utility preferences.
  • Discounted Thompson sampling provides a continual-adaptation layer that can be applied on top of any library of pretrained policies, not only the Pareto-front agents trained here.
  • The learned policies converge to a recognizable pattern, with buy and sell spreads slightly tighter than market and about 20 percent of inventory hedged per step, suggesting the RL agent discovers a simple interpretable market-making rule in this environment.
  • If the claims transfer out of simulation, trading desks could replace hand-tuned spread and inventory rules with agents that tune themselves to each market regime.

Reading between the lines

Editorial extensions of the paper, not claims the author makes directly.

  • The zero-fee, narrowest-spread routing rule makes the experiment a pure spread tournament; a natural next test is to add a per-trade fee or queue-position priority and see how much of the measured margin survives.
  • The dynamic penalty logic could be made volatility-adaptive by letting the risk coefficient track realized volatility; the thesis lists this as future work, so it is a testable extension rather than a claim.
  • POW-dTS is a general recipe for non-stationary RL: any domain that can supply a handful of pretrained policies could use the same discounted Thompson-sampling selector, for example robotics or recommendation systems.
  • The Pareto-front agent implies that inventory risk and profit are separable enough for an operator to choose a target point on the front; an empirical test would compare the front's best policy for a given utility against a scalarized agent tuned to that same utility.

Referee Report

4 major / 5 minor

Summary. This PhD thesis develops and evaluates reinforcement-learning (RL) market making agents in the ABIDES simulated market. Chapter 3 formulates market making as a deep Q-learning task with discrete buy, sell, and hedging actions, and studies single-agent, multi-agent, and direct-transfer scenarios. Chapter 4 addresses inventory management in two ways: a reward-engineered dynamic penalty called RIM with the AIIF and DITF coefficients, and a multi-objective agent called M3ORL that maintains separate Q-functions for mark-to-market and inventory objectives and uses Pareto-front tools. Chapter 5 introduces POW-dTS, a discounted-Thompson-sampling policy weighting method intended to adapt to non-stationary market regimes, and compares it with continual-learning baselines. The abstract's central claim is that the proposed RL-based approaches significantly outperform traditional and baseline algorithmic strategies across various performance metrics.

Significance. If the claims are taken in their stated breadth, the thesis would contribute useful techniques for RL market making: a dynamic inventory penalty that adapts to the agent's cash-to-inventory ratio, a Pareto-front multi-objective formulation with separate Q-networks, and a Thompson-sampling mechanism for combining pretrained policies. The experimental work is careful in several respects: most setups use 250 simulations, results are reported with rolling averages and standard deviations, multiple metrics are tracked (MtM, inventory, cash/inventory ratio, hypervolume, sparsity), and Chapter 5 includes an ablation study. The SHAP analysis and the reported evolution of buy/sell/hedge epsilons also provide useful interpretability. The main weakness is external validity: because the simulated investors always route to the narrowest spread and transaction fees are zero, the market making task reduces to a zero-sum spread competition, and the only baselines are a random and a persistent market maker. No classical market-making algorithm is implemented, so the abstract's phrase 'traditional and baseline algorithmic strategies' overstates what is actually tested.

major comments (4)
  1. [Abstract; Section 3.3.1; Section 4.1.2] The abstract claims that the proposed RL approaches 'significantly outperform traditional and baseline algorithmic strategies,' but the experiments only compare against a Random-MM and a Persistent-MM. No classical market-making strategy such as Avellaneda-Stoikov or a spread-based heuristic is implemented. Moreover, Section 3.3.1 states that the 50 investor agents always match with the MM offering the narrowest spread and that transaction fees are not considered; Section 4.1.2 repeats this design. Under these assumptions the market making problem is a pure zero-sum spread competition in which the dominant strategy is to undercut the spread, which is exactly what the DQL-MM learns (buy and sell epsilons converge near -0.2 to -0.4). The headline claim should be scoped to this simulated setting, or the experiments should include a classical baseline and variants with fees and non-greedy investor routing.
  2. [Section 4.1.2; Table 4.2; Table 4.3] The paper selects AIIF=0.2 as the best-performing reward configuration after testing ten AIIF values, but no multiple-comparison correction or pre-specified selection rule is reported. Given the reported standard deviations (for example, AIIF=0.2 gives MtM 12,833 ± 66 while AsymDamp gives 11,672 ± 162 over the tested sessions), the differences among the top configurations may not be statistically significant. The word 'significantly' in the abstract is not supported by significance tests. The authors should either provide paired hypothesis tests with an appropriate correction for the multiple AIIF values, or explicitly frame the comparison as exploratory.
  3. [Section 4.2.1; Eq. (4.19); Algorithm 3] The text states that alpha in R2(s,a) is only a scaling factor for the weight w and that it does not affect learning or agent performance. This is not justified by the equations as written: R2 enters the TD target for Q2, so different alpha values produce differently scaled Q2 estimates, and the greedy action selection argmax(w*Q1 + (1-w)*Q2) then changes the effective trade-off between the two objectives. If the Pareto-front results are robust to alpha, the authors should demonstrate this by showing that w is adjusted inversely with alpha or that Q-values are normalized before combination; otherwise the reported fronts and comparisons may depend on an arbitrarily chosen constant.
  4. [Section 5.4; Figure 5.9] The POW-dTS algorithm introduces hyperparameters alpha_inc, beta_inc, and gamma, and the experiments appear to use a single configuration (e.g., alpha_inc=1, beta_inc=1, gamma=0.4). No sensitivity analysis for these hyperparameters is reported, so the claimed advantage over continual-learning baselines may be specific to this hand-chosen setting. At minimum, the authors should report a small sensitivity study or justify the chosen values from the ablation.
minor comments (5)
  1. [Section 2.1.1] The heading 'Markov decission process' contains a typo; it should be 'Markov decision process'.
  2. [Section 4.2.1] The subsection title 'Multi-objetive RL MM: M3ORL' contains a typo; it should be 'Multi-objective RL MM: M3ORL'.
  3. [Definition 2, Section 4.1.1] The coefficient is written as 'Alfa Inventory Impact Factor' in Definition 2 but as 'Alpha' elsewhere; the spelling should be consistent.
  4. [Table 4.2] The table header and footnote notation (e.g., 'Experiment Avg 1 σ2 Var3') is difficult to parse, and the commas in values such as '413,121,21' appear to be formatting artifacts. Please reformat the table for readability.
  5. [General] The thesis is a compilation of published and submitted papers, but the chapters do not indicate which parts correspond to which source paper. A short note at the start of each chapter would help the reader understand the provenance and the amount of new material added.

No significant circularity: the RL-vs-baseline comparisons are external, and the self-citations are not load-bearing.

full rationale

The thesis's central empirical claim is that the proposed RL market makers outperform baseline agents in the ABIDES simulator. The baselines (Random-MM, Persistent-MM) are independent agents with the same action space, and the comparison metrics (MtM, inventory, cash/inventory ratio) are not used to construct the RL policies. The AIIF and DITF coefficients are hand-set or selected by sweeping over values, and the paper does not present the sweep as a prediction; the best AIIF=0.2 is reported as an experimental comparison among trained variants. The state/action spaces and reward functions are taken from the author's prior work and from Ganesh et al., but those citations are used for design continuity, not as the evidence for the reported outperformance; the experiments are reproduced in the thesis. The investor-routing rule (narrowest spread, zero fees) is an explicit simulation assumption, not an equation that makes the RL result true by definition; it makes the setting favorable to undercutting, which is a validity concern, not circularity. The word 'traditional' in the abstract is not supported by the baselines, since no classical market-making algorithm is included, but this is a comparison-design gap rather than a circular derivation. No step was found where a fitted parameter is renamed as a prediction or where a uniqueness claim is imported from the authors' prior work.

Assumptions & free parameters 4 free parameters · 4 assumptions · 0 invented entities

The central results rest on several hand-set coefficients: AIIF selected from test performance, DITF=0.5 chosen by hand, alpha=5 in the MORL reward, and POW-dTS hyperparameters. The environment assumptions about investor routing and zero fees are load-bearing for the claimed outperformance. No new physical entities or forces are introduced.

free parameters (4)
  • AIIF (Alpha Inventory Impact Factor) = 0.2 (chosen as best of {0, 0.2, 0.5, 0.8, 1, 1.5, 2, 5, 10, 100})
    Swept in Section 4.1.2 and selected after testing; it directly controls the inventory penalty and the reported 'best' reward function uses the best-performing value without multiple-comparison correction.
  • DITF (Dynamic Inventory Threshold Factor) = 0.5
    Fixed by hand in Section 4.1.2 to keep inventory value below 25% of total MtM; this choice shapes the dynamic threshold and all inventory results.
  • alpha in M3ORL R2 reward = 5
    Set in Section 4.2.1 from 'a first study of the preliminary results' to normalize R2; the paper claims it does not affect learning, but it does affect the weighted action selection during training.
  • POW-dTS hyperparameters (alpha_inc, beta_inc, gamma) = e.g., 1, 1, 0.4 in one shown experiment (Section 5.4.3)
    Discounting and update coefficients for the Thompson sampling policy weighting; full search or robustness analysis was not visible in the provided text.
assumptions (4)
  • standard math Bellman optimality and DQN convergence in the simulated environment
    The thesis assumes standard RL theory and that DQN with experience replay convergences to a useful policy in the ABIDES setting; applied throughout Chapters 3 and 4.
  • domain assumption ABIDES configured with 100 noise, 10 value, 10 momentum, and 1 POV agent approximates a standard financial market
    Section 4.1.2 states the goal was to generate a 'standard' market in terms of price volatility; this assumption underlies the external validity of all results.
  • domain assumption Investor agents always trade at the narrowest MM spread and transaction fees are zero
    Section 3.3.1 describes investors as 'consistently opting to match their orders with the MM offering the narrowest spread' and notes 'transaction fees were not considered.' This converts market making into a zero-sum spread competition.
  • domain assumption The 8 or 10 state features are Markov-sufficient for the market making task
    Sections 3.1.1 and 4.1.1 define the state space and assume it captures the relevant information (order counts, inventory, price variation, spread); no verification that additional features would not change the learned policies.

This thesis presents the results of a comprehensive research project focused on applying Reinforcement Learning (RL) to the problem of market making in financial markets. Market makers (MMs) play a fundamental role in providing liquidity, yet face significant challenges arising from inventory risk, competition, and non-stationary market dynamics. This research explores how RL, particularly Deep Reinforcement Learning (DRL), can be employed to develop autonomous, adaptive, and profitable market making strategies. The study begins by formulating the MM task as a reinforcement learning problem, designing agents capable of operating in both single-agent and multi-agent settings within a simulated financial environment. It then addresses the complex issue of inventory management using two complementary approaches: reward engineering and Multi-Objective Reinforcement Learning (MORL). While the former uses dynamic reward shaping to guide behavior, the latter leverages Pareto front optimization to explicitly balance competing objectives. To address the problem of non-stationarity, the research introduces POW-dTS, a novel policy weighting algorithm based on Discounted Thompson Sampling. This method allows agents to dynamically select and combine pretrained policies, enabling continual adaptation to shifting market conditions. The experimental results demonstrate that the proposed RL-based approaches significantly outperform traditional and baseline algorithmic strategies across various performance metrics. Overall, this research thesis contributes new methodologies and insights for the design of robust, efficient, and adaptive market making agents, reinforcing the potential of RL to transform algorithmic trading in complex financial systems.
