You will be taken to a Currency Exchange window. On the far right you will see a listing of all the people looking to trade either Robux or Tickets, and at what exchange rate they're offering.
You have to be very careful about the deals you make on the currency exchange -- you can lose a lot of money if you're not careful! Use your calculator and double-check how much you are offering.
A Robux ratio of "5,000 @ 1:5", for example, means that someone is selling 5,000, and is looking to buy 25,000, because she/he is buying them at a ratio of 1 to 5. In other words, 5000 multiplied by 5 is 25,000.
A market order is a buy or sell order to be executed immediately at current market prices. As long as there are willing sellers and buyers, a market order will be filled.
A limit order is an order to buy at no more (or sell at no less) than a specific price. This gives you some control over the price at which the trade is executed, but may prevent the order from being executed.
Which order should you choose? That depends. A limit order gives you a little bit more control over the price you wish to trade at. However, you have to be very careful with your math -- one typo can cost you lots of tickets or Robux. A market order gives you less control over prices, but transactions are quick and efficient.
My Open ROBUX< Positions shows the as of yet incomplete trades you have trading ROBUX for tickets. You can still cancel these trades by clicking "Cancel".
An example would be:
Offers 1000 of your Robux for 10,000 tickets at the rate of 1:10 (i.e., 10 tickets for every 1 Robuck). 1000 Robux have yet to be traded.
An example would be:
Offers 5000 of your Tickets for 2500 Robux at the rate of 2:1 (i.e., you are hoping to get 1 Robuck for every 2 tickets.) 5,000 of your tickets have yet to be traded.
Your trade history shows the completed trades you have made. (Don't use these trades as guidelines for your prices, these are just examples.)
A split trade will allow your trade to be broken up into smaller pieces among more than one buyer, which may allow your transaction to go through the exchange quicker.
