displaying, by a trading device, market data on a display unit of the trading device, the market data having a first portion and second portion;
detecting, by the trading device, gaze position data for a user with a sensor of a tracking mechanism of the trading device, wherein the gaze position data represents the user's gaze with respect to the display unit;
determining, by the trading device, a user focus area of the display unit based on a field of foveal vision for the user and the gaze position data with a gaze control application of the trading device, wherein the user focus area is associated with the first portion of the market data, wherein the second portion of the market data is associated with a second area of the display unit;
assigning, by the trading device, in response to determining the user focus area, a first priority to the first portion of the market data associated with the user focus area and a second priority to the second portion of the market data associated with the second area with a display manager of the trading device, wherein the first priority is higher than the second priority;
modifying, by the trading device, a first rate of updating, prior to being displayed in the user focus area, the market data in the first portion with the display manager of the trading device, wherein the first rate of updating is modified based on the assigned first priority;
