Post-Edit: Never mind. Ignore all of these numbers, the entire trading formula has been changed. It's no longer true that each skill in trading reduces the trading penalty by 10%... in fact, with 10 trading under the new system you will be skinned more than you were with 8 under the old one. When I have free time today I'll update this list to reflect the new formula.
EDIT: Numbers updated to reflect new skill cap!
Just doing some quick math, here are some approximate formulas for relative buying and selling penalties based upon your trade skill:
Ia = Item cost adjusted for your trading skill
Ib = Base item cost
T= Trading skill
For armor and weapons:
Buying:
Ia = (2.0093 -(1.0093*T)/10) * Ib
A person with 0 trading skill will pay slightly double the base cost of the item.
Selling:
Ia = (.331 +((1-.331)*T) /10) * Ib
A person with 0 trading skill will sell goods for roughly one third the base cost.
In order to afford a given good through trading, you have to sell about six times that good's value worth of items to obtain it.
Trade items:
Buying:
Ia = (1.2 - .02*T) * Ib
A person with 0 trading skill will pay 20% for a trade good than its base cost.
Selling:
Ia = (5/6 + T/60) * Ib
A person with 0 trading skill will receive 5/6ths of a trade good's base cost when selling.
A person with 0 trading skill has an exchange rate of 1.44; in other words, you would have to sell items totalling a base cost of 1440 to purchase items totalling a base cost of 1000.
Exchange rates based upon levels of trading skill:
Trade Goods exchange rate = (1.2 - .02*T)/(5/6 + T/60)
Weapons and gear exchange rate = (2.0093 -(1.0093*T)/10)/(.331 +((1-.331)*T) /10)
Trade good rates by level of trading skill:
0 trading: 1.440 (1440 coins worth of items sold per 1000 coins worth of items bought)
1 trading: 1.388 (1388 coins worth of items sold per 1000 coins worth of items bought)
2 trading: 1.338 (1338 coins worth of items sold per 1000 coins worth of items bought)
3 trading: 1.291 (1291 coins worth of items sold per 1000 coins worth of items bought)
4 trading: 1.244 (1244 coins worth of items sold per 1000 coins worth of items bought)
5 trading: 1.200 (1200 coins worth of items sold per 1000 coins worth of items bought)
6 trading: 1.157 (1157 coins worth of items sold per 1000 coins worth of items bought)
7 trading: 1.116 (1116 coins worth of items sold per 1000 coins worth of items bought)
8 trading: 1.076 (1076 coins worth of items sold per 1000 coins worth of items bought)
New with .700:
9 trading: 1.037 (1037 coins worth of items sold per 1000 coins worth of items bought)
10 trading: 1.000 (1000 coins worth of items sold per 1000 coins worth of items bought)
Armour / Gear trade rates:
0 trading: 6.070 (6070 coins worth of items sold per 1000 coins worth of items bought)
1 trading: 4.796 (4796 coins worth of items sold per 1000 coins worth of items bought)
2 trading: 3.889 (3889 coins worth of items sold per 1000 coins worth of items bought)
3 trading: 3.210 (3210 coins worth of items sold per 1000 coins worth of items bought)
4 trading: 2.682 (2682 coins worth of items sold per 1000 coins worth of items bought)
5 trading: 2.261 (2261 coins worth of items sold per 1000 coins worth of items bought)
6 trading: 1.912 (1912 coins worth of items sold per 1000 coins worth of items bought)
7 trading: 1.630 (1630 coins worth of items sold per 1000 coins worth of items bought)
8 trading: 1.388 (1388 coins worth of items sold per 1000 coins worth of items bought)
New with .700:
9 trading: 1.180 (1180 coins worth of items sold per 1000 coins worth of items bought)
10 trading: 1.000 (1000 coins worth of items sold per 1000 coins worth of items bought)
And so there you have it. I hope that was enough detail to gag an elephant.
Woot! Equal trading at ten skill!
