Select a market, choose a selection you want to lay and click on the best lay price/odds. 

In the following example, you are laying a team at odds of 1.87, the backer is staking Rs.100. Your liability of Rs.87 is taken from your balance as this is your worst case scenario. 

Your potential profit: Rs.100
Your potential loss: Rs.87

In this example, if the team wins the tournament, the total payout will be Rs.287. You have to pay Rs.87 to the winning customer, as the backer’s original stake is returned to them. If the team loses the tournament, you win Rs.100 minus commission from the betting exchange.
