There are two order types for trading on DINNGO.
Market Order: Buy/Sell at the best price available
A market order executes immediately against the best available price by prioritizing the speed of execution over finding a lower price. As long as there are willing sellers and buyers, market orders will be filled.
Once the market order is sent, it can not be canceled because it is filled immediately. (Please note that market order option is NOT available during beta testing.)
Limit Order: Buy/Sell at a specific price
A limit order is an order to buy or sell at a specific price to ensure a better average fill price. However, limit orders are not guaranteed to be executed. It may not be the case that adequate bids or asks to fill the order will appear on the market.
