Once you have selected the parameters for your trade, more fields will appear to provide additional details about your position in the bottom left.
All the fields here are important, but you’ll want to pay special attention to these:
Expected Price: the expected price of execution for your order. This price is only an estimate as the orderbook may change before your order is processed by the matching engine.
Price Impact: the difference between the expected execution price for your order and the best order on the bid or ask side. This will increase for larger trade sizes.
Fee Percent: fees percent based on the liquidity types and 30 day historical volumes.
Fee: fees are charged based on liquidity types. Maker orders cost less than taker orders.
Total: total order size including fees.
We have released a new volume-weighted maker-taker fee schedule that is more competitive with fees on centralized exchanges. dYdX uses a maker-taker fee model for determining its trade fees. There are two types of orders on dYdX — Maker and Taker orders.
Maker orders are orders that do not immediately fill and rest on the order book — these orders add depth and liquidity to the order book. Maker orders will always cost less than taker orders to execute the trade.
Taker orders, on the other hand, immediately cross existing Maker orders. They remove liquidity from the order book.
Once you have verified all the fields related to the position you are opening, simply click the “Place [market/limit/stop] order” button, and you should see a notification telling you that your position has successfully been filled.
