Trading means buying or selling shares. The price of a share, between 1 and 99 cents, corresponds (roughly) to the market’s estimate of the probability of that event taking place.
Example: The Donald Trump outcome in a presidential winner market trading at $0.51 indicates the market believes he has a roughly 51% probability of winning, at the given moment.
Buy shares in an outcome when you perceive the price as too low, or when you think your fellow traders are underestimating this likelihood. Sell shares, or 'short' the outcome when you think they are too optimistic.
The value of your shares will change over time. You may decide to sell your shares later on, either to take some profit or stop a loss. Or, you can hold onto your shares until the market closes. At that point, if the event in the market has taken place, shares will return $1. If it has not, sold (short) shares will return $1 instead.

Let's go step-by-step through the recommended trading process:
Once you've found a market you'd like to trade and are on the market's page, examine the market’s question and resolution details.
Because Augur markets are created by other users, sometimes the markets can be made with errors. If a market has an error, it is at risk to resolve as
invalid market; and shares in other outcomes will not pay. Therefore, It is important to make sure that:
The outcome will be known at market end time
The market question isn't subjective or ambiguous
The title, details, and outcomes are not in direct conflict with each other
The resolution source will provide a clear answer
Next, you'll want to get an idea of the market's trading volume (how much has changed hands) and open interest (sum of trades matched). Make sure that the event expiration leaves time for the outcome to be made known and that you're comfortable with the market's fee (paid to market creators and reporters).
The outcomes section displays the choices that you have to bet for or against. You can toggle between order books and charts by selecting an individual outcome.
Bid/Ask Quantity: These numbers convey the quantity of shares (to either buy or sell) for a particular outcome that is available to be matched on the order book.
Best Bid/Ask: At any moment in time, the best bid is the highest price someone is willing to pay for shares in an outcome. The best ask is the lowest price someone is willing to sell their shares.
Last (price): is the most recent price paid by anyone trading on an outcome.
Now, let's start your order!
You can buy shares in an outcome if you believe it will occur or that the price of the outcome will rise from its current level. Or, you can sell shares if you believe the outcome will not occur or that the price of the outcome will fall from its current level.
Once you know the outcome that you’d like to trade, you can take and complete an order that someone else had already posted to the order book; or you can create and post a new order to the order book with the order form.
Selecting the other side of an order that someone has already made is known as 'taking' an order. In the order book, to the right of the screen, orders in red are sell orders (offers); the quantities shown are available to buy at the listed prices. The orders in green (bids) are orders from users who wish to buy shares; the quantities show how much you can sell to them at the listed prices.
Selecting an available taker order from the order book automatically fills your order ticket.
Note: Taker orders require you to pay a transaction fee
Alternatively, if you do not see an order you would like to take, you can create a new order. First, select which outcome you'd like to trade; and whether you'd like to buy or sell; from the dropdown in the order section.
Note: Maker orders do not require you to pay a transaction fee, BUT you may not have your order filled quickly or at all.
Once you know the outcome you’d like to buy or sell, you may now choose the quantity of shares.
Now, enter the price that you’d like to submit your buy or sell order for. Every share has a price range between $0.01 and $0.99 (where the price roughly corresponds with probability, $0.99 = 99%). Every winning share pays $1 (minus fees).
This shows the amount of money required to make this trade. You can change this value to control the total cost of your order, and the quantity will adjust to compensate for the new total order value. So if you want to bet $40, enter 40 in here.
Review your entire order and make sure everything looks correct.
Order expiration allows you to set an expiration date which prompts the order to cancel. You can set the order expiration in numeric minutes, hours, days, or a custom interval.
Alternatively, you can select the dropdown for expanded ordering options:
Fill Only: Fill Only orders will immediately fill up to the specified quantity of available shares. If the order is only partially filled, whatever amount of shares remaining on the order will be immediately canceled.
Post Only: The post-only limit order option ensures the limit order will be added to the order book and not matched with a pre-existing order. If your order would cause a match with a pre-existing order, your post-only limit order will not execute. Post-Only Limit Order ensures that you will not pay a transaction fee.
If you are taking an order, placing the order by selecting the button should complete your trade.
If you are making a new order, once your order is matched by someone taking the other side, a trade is complete. If your order is not matched after some time, you may need to adjust the price of your offer.
Augur runs on a peer-to-peer network which requires micro-fees to be paid for transactions such as making trades. This is different from the market fee, and this fee is paid to miners on the Ethereum network.
A gas payment is not required for unfilled orders posted to the order book, but if you take an order already posted to the order book, a fee will be charged to fill the order.
This fee to miners is paid in a currency called ETH, but in order to improve the experience for users, Augur facilitates the ability for traders to only need to hold DAI for both trading and paying gas fees.
