Hey guys.
I've been meaning to ask in the forums for some time in regards to this. I figured it was better to post it here rather than in Guru seeing as it won't be around soon
I have been attempting to speed run the guild wars games for some time now. It takes a lot of careful planning to do so. When planning eliminating inconsistencies where possible is ideal. However, buy/sell price fluctuations at these traders is a constant issue. My speed running projects mean that I need to buy materials to craft armor or farm materials to sell for gold.
For example, in my Factions speedrun, I need to buy exactly 50 bolts of cloth at Seitung Harbour, as I get there to craft armor with it. Getting the armor at this point of the game is crucial for time efficiency and progression. I usually have only enough money to buy them at 140g per 10 (perhaps 150 or so? I forgot exactly where the cutoff is). Should the price increase too high, it would make doing efficient runs impossible.
Another example is in Prophecies where I need to farm feathers from outside Lion's Arch to get enough gold to buy high AR armor as soon as possible. This is the most accessible way of farming at that point in the game whilst also power leveling. Now, if feathers start only selling for 500g per 10, that means that the ability at how fast I can farm is diminished, whereas if the price jumps up to say 800, it suddenly becomes much quicker to get the gold I need to progress in the run.
Being able to understand these price changes may or may not help in trying to find a solution to my issue, but either way I feel like understanding their mechanics would help regardless. A few specific questions I had regarding the changing prices were:
1. Are the prices the same at every trader in the game at the same moment, or does the price vary from trader to trader (ie. in Seitung Harbor vs in Lions Arch, between different servers, etc.)?
2. Is there a price ceiling/floor in place on prices (I don't think they can sell for less than 100g per 10, is there an upper limit)?
3. What causes a material's price to either increase or decrease (is it based on supply/demand)?
4. How often do price changes occur (daily, hourly, instantaneously, etc.)?
5. Is there an artificial way of manipulating the prices offered at traders?
Any answers or additional information you think might come in handy would be much appreciated!
