Arbitrage Trading Bot Developer for Multi-Venue Edge
We develop arbitrage systems that net spreads after maker/taker fees, withdrawal delays, and partial fills—balancing inventory so one stuck leg does not freeze the book.
Paper arb disappears in production
Screenshots show 0.5% gaps; live nets 0.02% after fees—or negative when transfer stalls. Triangular arb on one exchange still hits queue position and balance drift.
- ×Withdrawal and deposit times not modeled; capital trapped on one venue.
- ×FX or stablecoin depeg breaks assumed parity legs.
- ×Concurrent legs fill asymmetrically leaving naked exposure.
- ×Rate limits prevent completing the exit leg during spikes.
Arb systems with inventory and transfer awareness
Pre-trade edge calculators, legged execution with timeout flatten, and treasury modules pre-positioning float on each exchange.
- Explicit min edge threshold after fees, slippage, and funding.
- Partial fill handlers that abort or hedge remainder automatically.
- Chain congestion monitors pausing cross-chain arb.
- P&L attribution per venue and per route for capital allocation.
Desks pursuing structural inefficiencies
Not latency HFT at nanoseconds—practical arb for crypto funds and prop shops with real capital constraints.
Cross-exchange spot arb
BTC/USDT and major alts across Binance, Bybit, KuCoin.
Triangular arb
Single-venue loops with balance sync and fee-tier optimization.
Spot-perp basis traders
Capture funding vs spot carry with hedge rebalancing.
Market making firms
Internalize arb between customer flow and external venues.
Real-world delivery examples
Stablecoin cross-exchange loop
Desk arbed USDT/USDC implied rates across three CEXs.
Net 8–12 bps per round trip after fees at 50k daily volume.
Spot-perp basis capture
Fund hedged spot long vs perp short when funding exceeded threshold.
Annualized carry improved 6% vs passive hold with auto-rebalance.
What you get
Edge calculator service
Real-time net edge including fees, est. slippage, and transfer cost amortization.

Log would-trade edges without capital at risk.
- 03
Live micro-size
Minimal capital to validate fill symmetry.
- 04
Scale float
Treasury module pre-positions per venue metrics.
- 05
Continuous tune
Weekly edge threshold review and route pruning.
Frequently asked questions
Is crypto arbitrage still profitable?+
Margins compressed but exist with proper fee modeling and float placement. We validate before build.
Do you need colocation?+
For cross-exchange retail arb, co-located VPS often suffices. Sub-ms HFT is a different engagement.
Cross-chain arb?+
Yes with explicit bridge risk, time bounds, and pause on congestion.
How much capital is required?+
Depends on routes; feasibility study estimates min float per venue.
Can arb run with subaccounts?+
Yes—treasury module tracks balances per subaccount and venue.
