We connected 3Commas to an exchange account, ran a DCA bot and a grid bot through a volatile week, and read through the 2022 breach that exposed 100,000 users' API keys. Here is what the paid tiers add and how the platform has changed since.
A trading bot platform has one job it cannot fail at: connecting to an exchange account and executing orders exactly as instructed, at any hour, without a human checking in. 3Commas has been doing that job since 2017, longer than most of its competitors have existed, and that history cuts both ways in this review. It means a mature product with a large bot library, and it means a company that already lived through the worst thing that can happen to a bot platform: its users' API keys ending up in the wrong hands.
What the bots actually do
We connected 3Commas to a spot exchange account and ran two strategies for a week: a DCA bot averaging into SOL on scheduled dips, and a Grid bot working a range on ETH/USDT. Neither missed an order, including through an overnight drop that would have required us to be awake and watching a chart at 4am to catch manually. That is the entire pitch of the product, and on this basic measure it delivered.
Signal Bot is the more interesting tool for anyone who already has a strategy: point it at a TradingView alert, a PineScript indicator, or a webhook from a custom script, and it converts that signal into a live order on your connected exchange. It does not generate ideas for you; it executes the ones you already trust, which is a meaningfully different product than the "set it and let the AI decide" pitch some competitors run with.
