How Pros Run Triangular Arbitrage Across Multiple Exchanges (Without Getting Rektd)

Triangular Arbitrage across 20 exchanges sounds like free money. It isn’t. It’s logistics.

Most people imagine:
A → B → C → A … and you print profit.

Reality: your competitors are market makers, bots, fee tiers, and exchange microstructure.

Here’s the pro model that actually scales:

1) Monitor widely, execute narrowly
Scan 20+ venues for pricing dislocations — but execute on a smaller “core set” where liquidity + API reliability are proven. More venues = more signals, but also more false positives.

2) Pre-position inventory
Cross-exchange arb doesn’t work if you rely on transfers during the trade. Pros keep working balances on multiple venues and rebalance later.

3) Profit is edge AFTER costs (x3)
Triangular arb is 3 trades. Your real P&L is:
edge – fees – slippage – spread widening – partial fill risk.

If your raw edge is tiny, it’s probably fake.

4) The real killer is the broken triangle
One leg fills, the next doesn’t → you’re suddenly directional in the worst moment. Pros keep fail-safe hedging tools ready (usually perps) and design hedge paths before entry.

5) Rebalancing is a separate engine
After a day of arbs, your inventory drifts across venues. If you don’t run rebalancing like a process, you eventually can’t trade.

The bottom line: Triangular arbitrage is real, but only for operators who treat it like a system — not a trade idea.
