In the X-Universe your skill and relation to races is measured in ranks. Player ranks have effects on the game difficulty and the magnitude of monetary rewards for missions.
Player Ranks
Fight Rank
Increased by killing stuff. Each Affects the ships spawned by the Opponent Balancing System (OBS) for fight missions and in UFJD sectors in combination with the number of hostile ships already in the sector. Each Ship class has a value of points given if killed In ; in general the bigger and tougher the ship killed is , the more points towards this rank you get. Ships killed by player owned ships out of sector give a reduced number of points. Affects the ships spawned by the Opponent Balancing System (OBS) for fight missions and in UFJD sectors in combination with the number of hostile ships already in the sector. If SETA is left on without player input for long periods the player Fight Rank will drop 2% every game hour (6 minutes on 1000% SETA).
The second to final mission of the Shady Business plot requires the destruction of a total of 50 capital ships which will give a high fight rank if done by a player piloted ship. If SETA is left on without player input for long periods the player Fight Rank will drop 2% every game hour (6 minutes on 1000% SETA).

Trade Rank
Increased by buying and selling wares and stocks at values favourable in comparison to the average. Credits earned from missions do not count to this rank. The sale of wares at equipment docks and trading stations do not count (even if highly profitable) as the sales price is always average. The This rank affects the amount of credits offered by missions and what ship classes can be found by return ship/return abandoned ship/return stolen ship missions. It is increased by buying and selling wares and stocks at values favourable in comparison to the average. The rank increases on the number of transactions and the magnitude of difference from the average price and not the profit or total credits made. This means buying and selling energy cells one at a time from cheap to expensive sources is a good way to boost this rank early on. This rank affects the amount of credits offered by missions and what ship classes can be found by return ship/return abandoned ship/return stolen ship missions. If For example if the player buys energy cells from a solar power plant at 12 credits and sells them at an ore mine for 20 credits the players rank would increase as the average price for energy cells is 16 credits. Thus, as one may expect, the sale of wares at equipment docks and trading stations do not count (even if highly profitable) as the sales price is always average nor do Credits earned from missions as they are not considered to be trading. If SETA is left on without player input for long periods the player Trade Rank will drop 0.25% every game hour (6 minutes on 1000% SETA).

The race rank you have represents how much the faction loves or hates you and affects the prices at which they are willing to sell/buy ships, if you are allowed to purchase certain factories and ships, which stations you can dock at or at, or if they want to shoot you out of the sky. Race ranks go from -5 to +10 and is based on a point system dependent on trade, missions and kills. The higher the class of ship killed the larger the influence it has on Race Rank.
