How this list is ranked
Alternatives are ordered by overlap with Arbitrage Agent: the same strategy category first, then shared secondary categories, whether both are automated bots or both manual tools, how much the markets each one lists overlap, and whether they share a pricing model. Every fact on this page comes from what each author publishes in its listing; nothing is sponsored and the order cannot be bought.
Performance is not a ranking factor, because POLBOTS does not verify it. Treat a tool's published results as the author's claim, and prefer the ones you can try before funding.
