The auction works on the principle of counter offers. You choose the option of currency exchange, specify your rate and volume for currency exchange. When buying, the system will automatically buy all lots at the most favorable exchange rate. It will buy until you run out of the currency of payment (no more than you have specified).
After pressing the "Buy" button:
The system looks at the direction of currency exchange and looks for lots at an auction where the exchange rate is more favorable for you.
The lots are bought one by one, starting from the most advantageous for you.
The function "Create a counter lot" — if the function is enabled, if the auction runs out of lots at a rate that is more advantageous for you, a counter lot will be created.
A counter lot, for example: you want to buy CR for rupees, but there are no profitable lots at the auction, a lot will be created in which you buy CR for rupees. If someone wants to buy CR for rupees, they will see your lot.
A list of your counter lots can be found at the bottom of the auction page. Incomplete transactions can be cancelled. You can see detailed information in the event log.
