Dashboard
DEX Functional Specifications - Dashboard
1. Purpose
The purpose of this document is to outline functional specifications for the Peerplays Decentralized Exchange (DEX) relating to the Dashboard page from the user's perspective.
2. Scope
The DEX will be a feature rich application that users will depend on to trade their native and sidechain assets. As development on the DEX continues the list of features available to users will grow. A Dashboard page offers users the ability to see their account activity at-a-glance as well as provide the essential actions users often take. In this way, the Dashboard provides the user the basics of the DEX on one page.
Specific functions covered include:
the Dashboard page
the Quick Order widget
the Quick Send widget
the My Activity list
the My Assets list
3. Process Overview
Two processes will be described here: using the Quick Order widget, and using the Quick Send widget.
3.1. Quick Order widget
Goal: The Quick Order widget must allow the following actions:
The user can quickly place a market order to sell an asset they own at the current market price.
The user can quickly place a market order to buy an asset at the current market price.
To create a buy market order:
User selects the buy tab in the Quick Order widget.
User selects the asset they wish to buy (ex. BTC).
User selects the asset with which they will pay (ex. ETH).
User enters the quantity of the asset they wish to buy (ex. 0.5).
The system displays to the user how much buying the asset will cost in terms of the selling asset. (ex. Buying 0.5BTC will cost 20ETH at current market rates.)
User clicks Place Order to initiate the buy market order.
The system displays a confirmation dialog to the user to ensure accuracy of the field inputs.
User accepts the confirmation dialog.

6. Glossary
Market order : Orders that are meant to execute as quickly as possible at the current market price. If you’re buying an asset, a market order will execute at whatever price the seller is asking. If you’re selling, a market order will execute at whatever the buyer is bidding. The biggest drawback of the market order is that you can’t specify the price of the trade.
Limit order : An order that sets the maximum or minimum price at which you are willing to buy or sell. The biggest advantage of the limit order is that you get to name your price, and if the asset reaches that price, the order will be filled. If the asset never reaches the limit price, the trade won’t execute.
