Reproducibility Variable Result LLM Response
Research Type Experimental Extensive experiments show that the proposed method achieves good and robust performance in various situations. ... 4 Experimental Results We follow the experimental framework of [Kelly et al., 2023a; Lai and Yang, 2023; Lai et al., 2024] to evaluate the performance of the proposed LTPSS. The experimental settings and more experimental results are put in Supplementary A.5.

Pseudocode No The paper describes the Krasnosel ski ı-Mann fixed-point algorithm through mathematical equations and prose (e.g., in Section 3.2), but it does not present it as a clearly labeled 'Pseudocode' or 'Algorithm' block or figure. The iterative steps and operators are defined within the text rather than in a structured pseudocode format.
Open Source Code Yes The supplementary material and code for this paper are available at https://github.com/laizhr/LTPSS.
Open Datasets Yes The MRs of different trading strategies on the 7 benchmark data sets are shown in Table 1. It indicates that LTP-PP performs well on the FF25 data sets, which are well interpreted by the Fama-French five factors. ... [Fama and French, 2015] Eugene F. Fama and Kenneth R. French. A five-factor asset pricing model. Journal of Financial Economics, 116(1):1 22, 2015.
Dataset Splits No The paper mentions evaluating performance over 'trading times' and 'next trading time' (e.g., 'At the t-th trading time, a trading strategy determines an LTP ˆLt+1 for the next trading time.'), which implies a temporal evaluation strategy. However, it does not explicitly provide details about specific training, validation, or test dataset splits, percentages, or methodology for partitioning the 7 benchmark datasets used in the experiments.
Hardware Specification No The paper discusses computational complexity (e.g., 'the overall computational complexity of LTPSS is O(N 3 log( 1 ε))') but does not provide any specific details about the hardware (e.g., GPU, CPU models, memory) used to run the experiments. No specific machine, server, or cloud instance specifications are mentioned.
Software Dependencies No The paper does not explicitly mention any specific software dependencies, programming languages, libraries, or solvers with their version numbers that were used to implement or run the experiments.
Experiment Setup No The paper states: 'The experimental settings and more experimental results are put in Supplementary A.5.' This indicates that the specific experimental setup details, such as hyperparameter values (e.g., for η and β), training configurations, or other system-level settings, are not provided in the main body of the paper.
