The trade sidebar allows you to choose the market, leverage type, trade direction, order type and leverage. Under Cross Margin, there is no leverage selection; leverage is a function of the entire Account’s collateralization.
The price chart is an easy way to view historical pricing with 1 day or 1 hour candlesticks. It incorporates all the standard tools and indicators that can be overlayed from tradingview.
The depth chart is only visible when selected in the top right hand corner of the price chart. The depth chart is a visual representation of the order book that shows cumulative bids and asks and their prices.
The order book shows the current open orders on dYdX (in the dYdX Market), or on the relevant DEX market.
Positions / Balances panel
The positions / balances panel can show different types of information depending on the selections you have made. When Isolated Margin is selected, the panel will show Open Positions. These are isolated margin positions that are currently open. When Cross Margin is selected, the panel will show Account Balances. These are your balances for all assets supported on dYdX which make up your overall account value and collateralization.
Additionally, the panel will also have tabs that relate to limit orders. Open Orders display limit orders that have been placed but have not yet been executed. Filled Orders are limit orders that have been filled in the past. For a detailed view of all previous orders - see the History page.
