Systems and methods for commission allocation

An electronic trading system comprising:

• a computing device including at least one processor configured to:
• determine a first commission for orders for a financial instrument on a price based on a lack of available liquidity at the price;
• in response to determining the first commission, in real time populate, over a communication network, a first trading interface of a first workstation with a first trading quad indicating a lack of available liquidity for the financial instrument and a first cost for orders at the price based on the price adjusted by the first commission;
• in response to input into the first trading quad, receive in real time, through the communication network from the first workstation, first trade command indicating a first order to buy or sell the financial instrument at the price, the first order received at a first time;
• in response to receiving the first trade command, in real time determine a second commission for orders at the price on a same trading side as the first order based on the first order providing available liquidity at the price, in which the second commission is less advantageous than the first commission;
• in response to determining the second commission, in real time populate, over the communication network, a second trading interface of a second workstation with a second trading quad indicating available liquidity that includes the first order for the financial instrument at the price and a second cost for orders at the price based on the price adjusted by the second commission;
• in response to receiving the first trade command, in real time determine a third commission for counter orders to the first order based on the first order providing available liquidity at the price, in which the third commission is less advantageous than the first commission;
• in response to determining the third commission, in real time populate, over the communication network, a third trading interface of a third workstation with a third trading quad indicating available liquidity that includes the first order for the financial instrument at the price and a third cost for orders at the price based on the price adjusted by the third commission;
• in response to input into the second trading quad, receive in real time, through the communication network from the second workstation, a second order that is on the same trading side as the first order for the financial instrument, the second order received at a second time, the first time being earlier than the second time;
• in response to input into the third trading quad, receive in real time, through the communication network from the third workstation, a third order that is counter to the first order for the financial instrument, the third order received at a third time, the first time being earlier than the third time;
• in response to receiving the third order, match the first order and third order;
• in response to matching the first order and third order, execute a trade for the financial instrument fulfilling at least a portion of the first order and third order and display, over the communication network at the first trading interface and the third trading interface, first and second indicia of execution of the trade, respectively, adjacent the first cost and the third cost;
• and
• in response to executing the trade, apply the first commission to the first order and apply the third commission to the third order.
