Arbitrex vs 3Commas
3Commas is one of the best-known bot platforms: DCA bots, grid bots, smart trades with trailing take-profit, all running on your exchange keys. Nearly all of it assumes a view on price. Arbitrex assumes none — every route is long one venue and short another, so the result comes from the spread converging rather than from the market going your way.
The risk you are taking is a different risk
A DCA bot in a downtrend keeps averaging into a losing position; a grid bot breaks when price leaves the range. A delta-neutral spread has neither failure mode — its risks are fees, liquidity and margin on the losing leg. Not smaller risks, but ones you can measure before entering.
Two legs, two venues, one intent
Arbitrex is built around simultaneous entry on two exchanges: it tracks both order books, sizes against real depth, and treats a partial fill on the second leg as a problem to handle rather than an edge case. Single-venue bot platforms have no reason to solve this, because nothing they run needs it.
Funding income without a directional view
Funding-rate divergence pays up to three times a day on a fully hedged position, and Arbitrex ranks those opportunities with the net yield after fees. It is the closest thing to a flat-market strategy, and it is not something a DCA or grid engine can express.
Where 3Commas is the better answer
If you hold spot and want to automate accumulation, rebalancing or a range strategy, a bot platform does that well and Arbitrex does not do it at all. The honest split: 3Commas for a directional book, Arbitrex for the market-neutral one.
Domande frequenti
Can 3Commas run cross-exchange arbitrage?
Its core products are DCA, grid and smart trades, which execute on one venue at a time. Cross-exchange arbitrage needs synchronised entry on two venues and a view of both books at once — a different problem from automating a single-venue strategy.
Which is safer for a beginner?
Neither is safe by default. A delta-neutral position removes directional risk, which is the one that empties accounts fastest, but it adds a second exchange, a second set of fees and margin to manage on the losing leg. Start by watching spreads without keys and size small.
Do I keep custody of my funds?
Yes, with both. Arbitrex trades through exchange API keys, so balances never leave your accounts, and the scanner itself works with no keys connected at all.
