EveTrader is an algorithm with several functions:

1. The main function is a trade bot that will update market order prices to undercut your competitors. EVETrader can update buy and sell orders for the current station, system or regional. EVETrader can detect non-profitable operations and stop updating those orders while no income from buy and sell operations is possible. EVETrader can detect low volume, temporary orders created by competitors to provoke you into changing the prices of your high volume orders and ignores them. EVETrader has a user defined limit for the maximum price change and is measured as a percentage of the initial order price. User may also define minimal sell order and maximal buy order prices, which bot cannot ovecome. This multi level protection scheme must meet requirements to safely compete with real players and other market bots.
2. EVE Trader automatically installs buy and sell orders. You need to define what items you want to buy and resell, maximal buy and minimal sell prices and quantity of items to buy. If you dont want that control, use autotrader instead.
3. The Market Exporter will export regional market order data to files in-game. Market Analyzer can process export files and suggest the best places to start buying and selling. Market Analyzer can also download market data via eve API. This is much faster then collect data in game, but rely on api server online status. Also regional data downloaded by api call missing citadel orders (besides regional buy orders). More information about market analyzer is here.
4. Traveling function and Deliverer. EVETrader is able to update orders in several regions as part of the same route and EVETrader can haul items from station to station with the Deliverer addon. More information about Deliverer is here.
5. The PlanetManager addon can be used with EVETrader. More information about PlanetManager is here.

EVETrader will require a full version license to start. Trial version of EVETrader will allow to trade skillbooks only due to the unavoidable sharing of the market, with other full version EVETrader users who must have priority. To start EVETrader, select EVETrader from the drop down menu on the front page and place the full version license into program installation directory.

As with any EVEPilot function, EVETrader requires a first run to be completed. The first run manual can be found here. After the first run has been completed, you can setup and start EVETrader.

Trader Settings Panel:

To turn on existing order updates, check the 'Enable Trade Function' checkbox. Order installation settings defined here.

To close the market window once the work has been done you need to check 'Close Market When Done'. If the market window is left opened, it might prevent the traveling function from working.

Tick 'Process Sell Orders' and 'Process Buy Orders' if you want to update prices for sell and buy orders respectively.

The 'Sell orders comparison method' group box has three methods to update sell orders:

1. 'Station sell orders only' is used to compare market prices from within the same station and update your order based on this information.
2. 'Same system sell orders' will compare your order price with system orders and update your order if any of system orders has better price.
3. 'Sell orders of region' will consider orders from the whole of the region and maintain the regional best offer for your items. This is good for zeroes.

The 'Buy orders comparison method' group box will do the same as the sell orders the with exception of the regional range buy orders which are treated as same station orders.

'Max Price Change' sets the maximum percent of a price that an order can change it's price to. Each time when you start bot or add an order while bot is paused or using order installer, EVEPilot saves the initial state of the order to memory and calculates limit price. The maximum price change is a percentage of the initial price. If the maximum price change is set to 5% and the initial price of your sell order is 1000 then the minimum price for the order will be 950 and in the case of buy order will have a maximum possible price of 1050. Please dont set this value higher then 10% if you dont use overpriced orders in the first place. A small tick box 'Real Time Editor' will allow to edit limit price manually without bot restart when price of the order reached limit price and order cannot be updated automatically. Maximum price change is a property of already exisiting orders. You may install order manually or use order installer and this limit will apply to the new order in both cases.

'Min Volume To Outbid' sets the minimum volume of the competitors orders to take notice of and react. This volume is measured as a percentage from the current quantity of items in the order.

The most valuable parameters of EVETrader are: 'Sell if profit more then' and 'buy if profit more then'. The profitability of sales, is calculated as the real profit you can achieve from buy-resell operations within the same station, system or region. The profitability of buy-resell operations depends on brokers fee and sales tax. Sales tax is paid by owner of the sell order when another person purchases items. Brokers fees are paid when the owner of an order sets the order up. Buy-resell operations will require the brokers fee to be paid twice and sales tax once. Weak trading skills might prevent you from getting income from a buy - resell operation. EVETrader will calculate your real profit and disable order updates if profit of the operation is less than the value defined by user. EVETrader does not prevent non-profitable operations but allows the user to make the decision of what to do with these orders.

During profit calculation, a few rules are applied:

• Profitability is calculated using the same range as buy and sell orders. If the comparison method is set to in-station only, buy orders that are in the same station are the only once that are taken into the profit calculation.
• If the 'Min Volume to Outbid' is enabled, EVETrader will also cut off low volume orders from it's profit calculation. The lowest volume is defined as a percentage of the initially entered quantity of the order.  
• If there are no sell or buy orders present, profit will be detected as negative (-1) and the order update suspended.

'Brokers Fee' and 'Sales Tax' are where you must enter you brokers fee and sales tax. These values can be found in the market window, in statistics of the personal orders. If you trade within the same station, take the brokers fee from the order setup window. This value considers your standings to the corporation and faction of the station where your order is setup. To level standings use courier bot. Minimal possible values for brokers fee and transaction taxes are 3.00% and 2.25% respectively.

'Price update interval (minutes)' is the minimal update interval that EVETrader will check and update orders. The minimum price update interval is 6 minutes. This setting works differently after CCP introduced relisting fee for updating orders. You can only increase update interval selected automatically, but not override it. Now bot works on first come first serve basis. Older, but not abandoned, market orders are never outbid. Update interval increases based on the update count of the order. 

Bot may skip order update if profit is low. As soon as profit never change very fast, bot will recheck profits every X minutes as you may define in Cache Duration

Real Time Editor allows you to change minimal sell order and maximal buy order prices without restarting bot. These limiting prices are taken from order installer tables or calculated from initial price, if max price change setting is enabled and hit first. Real time editor window appears every time, when order price reached limits:

This window will autoclose in 10 seconds and bot will continue its operation. To start work with Real Time Editor click 'Stop' button to have more time. Editor will show name of the item, current buy and sell order prices from regional export file and your limiting price. To change limiting price edit value of the box. To select new price faster you can use buttons: Average + 50%, Average and Average - 50% or vertical scroll bar. When new price is set, click 'Set New Price' button to close editor and continue.

Real Time Editor supports autoupdating of limiting prices. If autoupdate is activated, bot will slowly shift limiting price by X% every Y minutes if current market price for the item reached limiting price. X and Y may be defined by a user. Slow limiting price correction allows to follow weekly price change fluctuation, but filter out temporary price change when one person installed unprofitable order to manupulate prices or due to an error.

Please dont install orders of the same items with the same entered amount to buy or sell. As soon as such order updated, vertical position of the order in order list may change and bot will generate desynchronization error and skip processing of all orders below!
