How do trading bot vendors charge, and why does it matter?

The main models, ranked by incentive alignment

A one-time license or a plain subscription is the cleanest structure: the vendor's revenue does not change whether you trade once a month or a hundred times a day. This is how we price our own desk — one flat license, no cut of anything, no subscription.

Volume-linked models deserve more suspicion. A vendor paid per trade, per contract, or through broker rebates benefits when you churn. Performance-fee models sound aligned but usually are not for retail: they capture upside while you alone hold the downside, and legitimate performance-fee arrangements normally live inside regulated advisory relationships, not software licenses.

• Flat license / subscription: cleanest — revenue independent of your activity.
• Per-trade or rebate-linked: vendor benefits from your churn; scrutinize hard.
• Performance cut on software: usually a regulatory and incentive red flag for retail.
• Deposits to the vendor: not a pricing model — a custody red flag that overrides everything else.

Questions to ask before paying anything

Ask the vendor to complete this sentence: 'We get paid when ___.' If the honest answer involves your trading activity, your deposits, or recruiting others, price that into your trust accordingly. Then ask what happens when you stop paying — good software degrades gracefully or keeps working; hostage models that lock your data or positions are telling you who owns whom.

Finally, ask what the total cost of operation is: subscriptions, data fees, VPS hosting, and the trading costs the strategy itself generates. A cheap license driving an expensive trading pattern is not cheap.
