Before placing an order, please confirm whether the digital assets and the TWD balance in the account are sufficient to pay for the order and other related expenses. When the order is established, it will be placed on the order book waiting for the match. Our matching engine is based on price priority. Which is similar to the five-price scale form in the stock market.
All types of purchase and sale orders have both Maker and Taker. Makers’ Order will be matched with Takers’ existing orders (pending order provided by maker) because the two play different roles in the transaction, so some exchanges charge them with different fees. ACE keeps it simple by charging users with the same fee.
You can place orders in any form. Currently ACE offers limit and market orders. In the future, ACE will continue to develop new trading forms to enrich users’ trading options.
Before your order is successfully matched, you may cancel the order from the “Open Order” list without paying any fee. According to “3. Market Order”, market orders do not provide the function of canceling.
2. Limit Order
The limit order is an order placed to execute a buy or sell transaction at a set number of trading pairs and at a specified limit price or better. When the market’s liquidity is low and transaction prices are changing drastically, the limit order made by the customer may not be a guaranteed match.
The priority of each is depended on the price and the quantity. If there is no such price, or the order quantity of such price is insufficient. Then this order will be on hold till there’s another transaction that matches.
3. Market Order
The market order is defined as a purchase order that is immediately matched with the currently available price on the exchange. Market orders will not guarantee the traded price and the market orders may be matched with several different prices.
4. Matching and Order Priority
ACE matches Taker Orders with Open Maker Orders on each Order Book based on Price-Time Priority. Price-Time Priority means that each time a Taker Order is posted, the Taker Order is matched with the best price on the Order Book on a First-In-time basis.
5. Trading Fees
ACE charges a fee for each order that is posted to the Order Book. The fee is calculated as a percentage of the Order quantity and will automatically be deducted. Please refer to Fees and Rates for current fees.

- Trading behavior indicative of intent to exploit known / unknown platform vulnerabilities.
