添加或消耗流动性的概念既适用于股票，也适用于股票/指数期权。一个定单是消耗流动性还是添加流动性，取决于定单是适销还是非适销。

适销定单会消耗流动性。
适销定单要么是市价定单，要么是限价等于或高于/低于当前市价的买入/卖出限价定单。

1. 对于适销的买入限价定单，限价等于或高于卖价。

2. 对于适销的卖出限价定单，限价等于或低于买价。

举例：
XYZ股票当前卖价尺寸/价格为400股/46.00。您输入一个买入限价定单，即以46.01的价格买入100股XYZ股票。由于定单马上就能执行，其将被视为适销定单。如果交易所会对消耗流动性收费，则客户将需缴纳该费用。

Effective August 1, 2012, a new tax will be implemented on the purchase of certain French securities.

Tax Rate

The initial announced tax rate was to be 0.10%; however based on updated information the applied tax rate is intended to be 0.20%.

Effective January 1, 2017 the rate will increase from 0.20% to 0.30%.

Scope

The FTT will be applied to shares of companies whose head office is located in France and whose market capitalisation exceeds EUR 1 billion. The French authorities will update a list each December with the names of companies which meet these requirements. At its launch, 109 French companies will fall under the scope of the FTT.

The purchase of a derivative contract is not subject to the FTT; however the acquisition of the underlying stock upon exercise or delivery of the derivative instrument will be subject to FTT. Similarly a convertible instrument will become subject to the FTT upon conversion or exchange into the stock.

American Depsitory Receipts (ADRS) are similarly subject to the FTT however the implementation date has been delayed to December 1, 2012.

Corporate action events which result in the acquisition of a French security subject to the FTT regulation, will have tax applied at the processing date.

Under the present rules, you can trade CFDs on French shares without incurring FTT in the same way as you are able to trade UK share CFDs without incurring stamp duty. All shares affected by the French FTT are available to trade as IB CFDs.

Please click here for for detailed information and frequently asked questions about our CFD offering.

Calculation Method

The legislation allows for the application of FTT based on the daily net purchase per final beneficiary. As an Investment Services Provider (ISP), Interactive Brokers will report FTT to our various clearing agents. As such, transactions will be eligible for netting if the shares settle at the same location. For instance, purchases and sales in France may be netted; however a purchase in France will not be netted against a sale in Germany.

IBKR's option commission charge consists of two parts:

1. The execution fee which accrues to IBKR.  For Smart Routed orders this fee is set at $0.65 per contract, reduced to as low as $0.15 per contract for orders in excess of 100,000 contracts in a given month (see website for costs on Direct Routed orders, reduced rates on low premium options and minimum order charges); and 

2. Third party exchange, regulatory and/or transaction fees.

In the case of third party fees, certain U.S. option exchanges maintain a liquidity fee/rebate structure which, when aggregated with the IBKR execution fee and any other regulatory and/or transaction fees, may result in an overall per contract commission charge that varies from one order to another.  This is attributable to the exchange portion of the calculation, the result of which may be a payment to the customer rather than a fee, and which depends upon a number of factors outside of IBKR's control including the customer's order attributes and the prevailing bid-ask quotes.

Exchanges which operate under this liquidity fee/rebate model charge a fee for orders which serve to remove liquidity (i.e., marketable orders) and provide a credit for orders which add liquidity (i.e., limit orders which are not marketable). Fees can vary by exchange, customer type (e.g., public, broker-dealer, firm, market maker, professional), and option underlying with public customer rebates (credits) generally ranging from $0.10 - $0.90 and public customer fees from $0.01 - $0.95. 

IBKR is obligated to route marketable option orders to the exchange providing the best execution price and the Smart Router takes into consideration liquidity removal fees when determining which exchange to route the order to when the inside market is shared by multiple (i.e., will route the order to the exchange with the lowest or no fee).  Accordingly, the Smart Router will only route a market order to an exchange which charges a higher fee if they can better the market by at least $0.01 (which, given the standard option multiplier of 100 would result in price improvement of $1.00 which is greater than the largest liquidity removal fee).
