Arbitrage types

The arbitrage type is determined by the markets of the bundle's two legs: leg A is in the MAX role, leg B in the MIN role (see "Trading → Bundle").

Type	Leg exchanges	Polarities	Status
Perp — perp	different	both	supported
Perp — spot	different or the same	convergence	supported
Spot — spot	different	—	not supported: requires moving funds between exchanges

Execution is the same for all types (see "Trading → Execution"). The "Arbitrage type" switch in the screener selects the mode of searching for opportunities; the terminal executes an opportunity it has found with a bundle of a supported type (see "Screener → Modes").

Perp — perp

Both legs are perpetual contracts on different exchanges. The polarities are "Convergence" (short MAX, long MIN) and "Divergence" (long MAX, short MIN). If a leg's exchange works in one-way position mode, the polarities take turns: the second one opens after the position of the first one is closed (see "What is Profit Cloud → Exchanges → Position mode"). Funding accrues on both legs (see "Trading → Journal → Funding").

Perp — spot

The perpetual contract is leg A, spot is leg B. The direction is fixed: short the perpetual contract, long spot — convergence only; the legs do not swap places. The spot leg has no leverage and no margin; exiting it means selling what was bought. Funding is only on the perpetual leg. Both legs can be on one exchange — then on one connection.
