2.1.1 Trading UI introduction

August 09, 2020

Below is a screenshot of the trading UI with some annotations in red to highlight the main elements and their functions.

Trading UI1 2.1.1 Trading UI introduction

The price Chart is a highly customizable view of the price history and trading activity of the contract you have selected. Down the left-hand side and across the top of the chart are various tools and customization options for you to explore.


The depth Chart gives a visual representation of the current quantity and price level of open buy or sell orders in the orderbook.


Orderbook provides the numbers behind what the Depth Chart shows, the red numbers are sell orders and the green numbers are buy orders. The larger green or red number in the middle of the orderbook is the last traded price, and the white number to the right of it the ‘mark’ or market or true price of the instrument, which is updated every 30 seconds.


Trade Ticket is where you place your orders into the market/execute your trades. At present we offer ‘Limit’ and ‘Market’ orders. A limit order is an order where you decide the price, it either executes a trade (this is known as a taker order as it is taking an order that someone already has in the market) or adds an order (maker – adds an open order at a price above or below market price) to the book at a price defined by you, whereas a market order executes at the currently available ‘market’ price. A ‘taker’ limit order is essentially the same as a market order. Limit orders are generally used to place open orders into the book.


The below examples show the BTC-USD spot market, however, the trade ticket works the same for all of our markets.


Limit order example: buying 0.003 BTC at $12,270.7 is taking an order already in the market as shown in the orderbook on the left of the screenshot.


In the ticket, the top field labeled ‘USD’ is the field in which desired order price is entered, the field labeled ‘BTC’ is where the trade size/quantity of BTC to trade is entered, the ‘USD’ field below that is if you want to give a trade size denomination in USD instead of BTC.


If you input a USD value, the platform will convert it to BTC and populate the BTC field automatically. Conversely, if you populate the BTC field, the system will auto-populate the USD field.

Market order example: buying .003 BTC at ‘Market’ (which is actually also $12770.7 in this case).

Once you have selected BUY/LONG you will then see a small green ‘order filled’ notification appear in the bottom right corner of the screen. Then you will see that the USD balance has reduced and that the BTC balance has increased under the trade ticket.


Market Trade History:

The Trades section simply shows the essential details of all recently executed trades from all participants in the selected market. If the trade is in green the taker order was a buy; if red, the taker order was a sell. The time of the trade is given as well as the size of the trade.

Collateral Information:


Available Balance: After selecting a trading pair, the available balance will display the balance of the coins which correspond to the pair.


    • Spot books: balance of each asset of the pair in question minus currently open orders in an orderbook.
    • Derivative books: dollar value of all tradeable collateral in the account. If you have an open order in the spot book, this is still available as collateral balance.


Portfolio Margin: This number represents the minimum USD value collateral needed for either current open position/s, open orders in the Orderbook or a combination of the two.



Collateral Balance: The balance of all currencies that can be collateralized in the account.


Margin Ratio & Margin Gauge: 


    • If the portfolio margin is under 50% of the collateral balance (under 50% margin ratio) then you can do whatever you want with the position including adding to it.
    • If the portfolio margin is between 50% and 100% of the collateral balance (between 50% and 100% margin ratio) withdrawal and transfer of collateral is not allowed.
    • 100% margin ratio reached = liquidation.
