Self-trade liability in algorithmic trading depends on manipulative intent and accurate factual assessment, not mere occurrence.

Self-trades in algorithmic trading are not automatically manipulative under the PFUTP framework; liability depends on whether the trades, viewed in the totality of circumstances, created a false or misleading market appearance with supporting evidence of intent or manipulation. The tribunal noted that self-trade volume is only one factor and that the incorrect reliance on an exaggerated percentage materially affected the adjudication. It also held that adequate hearing had been given, so the natural justice objection failed. Because the order rested on an erroneous factual basis, the penalty was set aside and the matter remitted for fresh adjudication on the correct record.

Issues: (i) Whether the appellant's self-trades in algorithmic trading constituted manipulative conduct attracting liability under the PFUTP Regulations and the stockbrokers' code of conduct. (ii) Whether the impugned order could be sustained despite the incorrect calculation of self-trade volume and the alleged denial of adequate opportunity of inspection.

Issue (i): Whether the appellant's self-trades in algorithmic trading constituted manipulative conduct attracting liability under the PFUTP Regulations and the stockbrokers' code of conduct.

Analysis: Self-trades do not involve change in beneficial ownership, but they may still create a false or misleading appearance of trading if accompanied by material showing intention or manipulation. The applicable framework requires assessment of whether the trades were intentional or accidental, and volume is only one relevant factor. The circular issued by SEBI on self-trades also recognizes that mere occurrence of self-trades is not per se illegal in the absence of supporting evidence of manipulation. The tribunal found that the adjudicating authority had relied heavily on an incorrect percentage of self-trades and had not properly examined the other surrounding circumstances, including the automated nature of algorithmic trading.

Conclusion: The finding of manipulative self-trading could not be sustained on the material as considered, and the issue was answered in favour of the appellant.

Issue (ii): Whether the impugned order could be sustained despite the incorrect calculation of self-trade volume and the alleged denial of adequate opportunity of inspection.

Analysis: The self-trade volume was wrongly calculated as about 4%, whereas the correct figure was about 1.95%. Since the impugned order substantially rested on that erroneous calculation, the matter required reconsideration. The tribunal, however, held that adequate hearing had in fact been afforded, and the complaint of violation of natural justice was not made out. As the adjudication itself was vitiated by the incorrect factual basis, remand was necessary for a fresh decision after appropriate consideration of the relevant factors and any fresh request for inspection.

Conclusion: The impugned order was unsustainable and was set aside, with the matter remitted for fresh adjudication; the natural justice challenge failed.

Final Conclusion: The penalty order was quashed and the dispute was sent back for reconsideration on the correct factual and legal basis, resulting in relief to the appellant while preserving the adjudicating authority's power to decide afresh.

Ratio Decidendi: In self-trade cases, liability under the PFUTP framework depends on proof of manipulative intent or misleading market appearance from the totality of circumstances, and an adjudication founded materially on an incorrect factual computation cannot be sustained.
