Apifiny Trading Rules

The following set of Trading Rules governs orders placed by Traders on the Apifiny Asset Network. Capitalized terms not defined herein shall have the meanings ascribed to them in the Apifiny User Agreement

1. Trading

1.1. Apifiny operates a central limit order book trading platform and settles trades in a number of Digital Asset Pairs. Each Trader’s Apifiny Account will list which Digital Asset Pairs are available to the Trader.

1.2. Orders

1.2.a. To place an Order on an Order Book, a Trader must have an Available Balance of the relevant Digital Asset in their Apifiny Account which is sufficient to cover the total value of the Order plus any applicable fees.

1.2.b. When a Trader places an Order, that quantity of the relevant Digital Asset becomes subject to a Hold.

1.2.c. All Orders on the Marketplace shall be treated as Limited Orders.

1.3. Limit Orders

1.3.a. A Limit Order is an Order to buy or sell a specified quantity of a Digital Asset at a specified price.

1.3.b. A Limit Order will only ever Fill at the specified price or a better price.

1.3.c. Each Limit Order will remain on the Order Book until cancelled by the Trader.

1.3.d. If an Order is posted to the Order Book at the same price as one or more existing Orders, it is a Taker Order which will result in an immediate Fill at that price, to the extent of the total quantity of those existing Orders.

1.3.e. To the extent that an Order is posted to the Order Book at a different price to all existing Orders, it is a Maker Order which will remain open at that price on the Order Book until it is canceled by the Trader.

1.4.b. Apifiny will periodically update these Order Minimums and Order Maximums to reflect the current state of our marketplace and the notional value of the assets.

1.4.c Each Trader (other than market makers) may not transact in over 100 Orders per day.

1.4.d Each Trader (other than market makers) may not have more than 30 unfilled Orders at any time.

2. Matching Engine and Order Priority

2.1. Apifiny matches Taker Orders with Open Maker Orders on each Order Book based on Price-Time Priority.

2.2. Price-Time Priority means that each time a Taker Order is posted: The Taker Order is matched with the earliest in time Maker Order at the best price on the Order Book; and to the extent that the Taker Order is not completely Filled by that Maker Order, it is matched with any subsequent Maker Orders at that price, in the sequence those Maker Orders were posted; and to the extent that the Taker Order is not completely Filled by one or more Maker Orders described above, it is matched with one or more Maker Orders at the next best price, in the sequence those Maker Orders were posted, and this process is repeated until the Taker Order is completely Filled. An Order may be matched with a number of corresponding Orders at the same price.

2.3. Fills and Settlement 

2.3.a. When a Maker Order is matched with a Taker Order, those Orders are Filled. An Order may be matched with and Filled by one or more Orders at the same price.

2.3.b. Apifiny settles all Filled Orders immediately, by debiting and crediting the relevant balances of Digital Assets in both Traders’ Apifiny Accounts.

3. Trading Fee

3.1. Apifiny charges a fee for each Taker Order and Maker Order that is posted to the Order Book. The fee is calculated as a percentage of the Order.

3.2. The current fee rates can be found at Apifiny.com.

4. Market Integrity

4.1. All Fills are final and will not be reversed unless:

  • Apifiny is compelled to do so by any applicable law or regulation; or
  • Due to a serious technical error, Orders or Fills do not occur as specified in these Rules – in which case Apifiny will make all reasonable efforts to restore all Traders to the position they would have been in had the error not occurred.

4.2. Apifiny may cancel Open Orders in the following circumstances:

  • Orders placed by Traders who, in our sole discretion, have engaged in abusive use of the platform, for example, Market Manipulation, or using the API in a manner which unreasonably burdens the platform.
  • Orders which under the circumstances involve an obvious error with respect to price, quantity, or other parameters – a ‘clearly erroneous transaction’.
  • If required by any applicable law or regulation, including specifically where Apifiny is required to suspend or terminate a Trader’s Apifiny
  • If required for technical reasons.

4.3. Interruptions

If technical reasons prevent or degrade Traders’ ability to place or cancel Orders, or prevent or degrade access to the Apifiny Sites or affect the operation of the Marketplace or matching engines, then Apifiny may, in its discretion, take one or more of the following actions in respect of one or more Order Books;

  • Temporarily disable depositing or withdrawing Digital Assets.
  • Cancel Open Orders.
  • Disable the ability to place new Orders.
  • Disable sign-in.
  • Disable APIs.
