Guild Wars 2

The new TP API updates very rapidly, every few seconds instead of minutes compared to the gw2spidy API. Using this, a web app can check an item’s price and compare it with prices you entered, so for example when a sell price is below the your threshold, the program will talk to you to buy it!

Web app: http://gw2timer.com/tp

The web app superficially shows a spreadsheet of rows containing item name, current buy price, and current sell price. Each row is actually a calculator, and to use it you click on the longest textbox and type a search query—results (items) will show up as you type. Click on a result and the calculator will retrieve the price data and do investment infos automatically.

The data is very condensed so they also fit in the overlay app To know the function of each input (black)/output (gray) textboxes, hover your mouse on the first row/calculator in the spreadsheet, and hover over each textboxes to read the explaining tooltip. If you need more help, click the [+?] link near the buttons.

When you open that web app section of the website, the app will by default refresh price data every 30 seconds; you can change the frequency in the Options page (cog icon) under Trading, and the number of calculators and search results too.

To use the voice notification, look at the 6 bottom-most textboxes:
Your Buy Price (A) < Actual Buy Price (B) < Your Buy Price ©
Your Sell Price (D) < Actual Sell Price (E) < Your Sell Price (F)

Cells A, C, D, F are what you can put in (or leave empty), and cells B and E are given by the calculator’s search result. Let’s say that silk scraps are 2.13 (2 silver 13 copper) and you want to buy them when they are less than 1.9 (1 silver 90 copper). To set the notification, just type 1.9 in cell F, which means Actual Sell Price < Your Sell Price. As another example, let’s say you want to sell silk scrap when their prices are 3 silver or higher, then simply put 3 in cell D. To turn off notification, either erase the price you typed, or click the “Notify” checkbox on that calculator.

The app was rushed released today after yesterday’s release of the new TP API, so please do give suggestions on improving it.
