2. Trade on exchange：
On the left side of the page, select the trading pair you would like to trade with. Take the DICE token as an example. If you would like to trade DICE tokens, select the“DICE/TRX”trading pair to enter the trading page.
Use the tab at the bottom to trade. Currently, there is one way: Limit. Let's say you would like to trade DICE tokens and choose the limit way.
Limit trading: Click “Limit“and enter the price/TRX in the upper bar and the amount in the lower bar in the “Buy” column. Click "BUY" to get the token.（The trading amount has to be more than 10 TRX）
You can see your balance at the Balance bar. Don't make your trading amount exceed your account balance.
On the confirmation page, you can specify whether you would like to sign automatically and the signing interval to suit your needs.If you do not want to see the authorization window every transaction, you can select "Until the next login" and click "Accept".
After the transaction is done, you need to wait for around 2 minutes for the block to confirm. After the confirmation, the TRX that is bought and spent will be updated to the account, and the transaction will also show in the transaction record below. ( Note: The money will be deducted after the transaction is submitted, but it does not mean that the trade is successful. You need to wait for the trade to be matched. You can cancel at any time under the current order. )
Similarly, follow the same steps to sell the tokens in the right tab.
