Confirm that the symbols, quote currency, contract size and product type are genuinely comparable.
Compare markets with a clear view of timing, spread, fees and execution risk before treating a difference as an opportunity.
Overview
Exchange arbitrage seeks to identify a temporary difference in the quoted price of the same or economically related instrument across different venues. The apparent difference is not the same as a guaranteed profit.
Quotes can change before both sides are completed. Spread, trading fees, transfer costs, funding delays, liquidity and currency conversion can remove or reverse the apparent difference.
Evaluation
Confirm that the symbols, quote currency, contract size and product type are genuinely comparable.
A timestamp difference can create a gap that no longer exists in an executable market.
Subtract Bid/Ask spread, venue charges, ticket fees, financing and conversion costs.
The displayed top price may cover only a small quantity, while the rest executes at worse levels.
Assets or funds may not move between venues fast enough to complete the intended sequence.
Decide what to do if one side fills and the other is rejected, delayed or repriced.
Platform presentation
Where comparison tools are available, AegeanOil can present cached prices and market context in one workspace. This information is for analysis. It does not guarantee that both prices are executable at the displayed quantity or that a difference will remain available.
