How to read it

Three cost models dominate: flat subscriptions, per-trade fees (DEX/Telegram bots at 0.5-1%, exchange-native at 0.05% or less) and volume-based platform fees on top. The ranking applies your exchange fee input to every platform except per-trade models, where the platform fee replaces the exchange fee - the only honest way to compare Pionex against a 3Commas subscription. Plan estimates use each platform's cheapest paid tier with annual billing where cheaper; bot-count and volume limits may force a pricier plan, so treat results as estimates and verify in the linked reviews.

What "free" actually costs

Exchange-native bots are free and pay exchange fees only - the baseline every subscription has to beat. Self-hosted open-source bots add a VPS (entered above) but remove API-key custody risk entirely. Fee-based models only make sense at low turnover or with a documented edge - see the free lane.
