Open one of your shop configs, find the product you want to enable dynamic price.
Like I want to enable for this product:
A:
display-name: 'Custom Name!'
price-mode: ALL
product-mode: CLASSIC_ALL
products:
1:
material: sea_lantern
buy-prices:
1:
economy-type: exp
amount: '5+({buy-times-server}-{sell-times-server})*0.2'
max-amount: 15
min-amount: 1
start-apply: 0
placeholder: '{amount} Exp'
sell-prices:
1:
economy-type: exp
amount: '5+({buy-times-server}-{sell-times-server})*0.2'
max-amount: 15
min-amount: 1
start-apply: 0
placeholder: '{amount} Exp'First, you need set price-mode to ALL or ANY.
Set amount option to the value you want here, like put a common dynamic formula here, if your math is not good, let me explain it:
5 is base price, which means the start price.
0.2 is each time one player buy or sell one this product, then the price will up or down.
We also added
max-amountandmin-amountoption, to avoid price is too high or too low.
The formula you set here is not limited, but you need carefully check whether player can earn money by purchase them then just sell them without do anything. Because of this, the max-amount and min-amount option is very important. For example, you set:
Buy Price Formula:
2.8+{buy-times-server}*0.1-{sell-times-server}*0.06Sell Price Formula:
2.38+{buy-times-server}*0.1-{sell-times-server}*0.06
In this way, your max-amount option should be lower than the price at the n(th) purchase or sellling time.
How to get the number called n? This number must meet:
[(Buy Price Base Price - Sell Price Base Price)/(Buy Up Price - Sell Down Price)] >= Accumulation from 1 to n.
In this example: (2.8-2.38)/(0.1-0.06) >= 1+2+3+4 (if up to 5, the formula will not meet), so n max number is 4 in this example.
Remerber: Your different formulas require reasonable setting of different values in max-amount and min-amount. The safest approach is to set the price of each purchase or sellling change to the same value.
Another common dynamic price formula is price changed based on the percentage, like: 100 * (1.5 ^ ({buy-times-server}-{sell-times-server})). In this example:
100 is base price.
1.5 is the multiplier of the price after each purchase or sellling.
In this example, first time buy with no sell is 100, then is 150 (+50%), then is 225 (150 + 150 * 50%).
Don't forget set
min-amountoption to a number near 100 to avoid the price become too low!
Available Placeholders
You can set placeholders (including PlaceholderAPI) and Math Calculate Format in buy-prices, sell-prices section's amount option and buy-limits, sell-limits section's value in shop configs.
Available built-in placeholder, for more info about them, please view Built-In Placeholders page.

Also in buy-prices and sell-prices section, you can set new 2 options:
max-amount: Price max amount, useful for dynamic prices. Optional.
min-amount: Price min amount, useful for dynamic prices. Optional.
Please carefully note that if you want to use our PlaceholderAPI extansion's placeholder, you have to use our new format, for example:
buy-prices:
1:
economy-plugin: Vault
amount: '15 - {sell-times-player} * 0.1 + %ultimateshop_farming_B_sell-times-player% * 0.1'
# We use the new format without { and } symbol.
placeholder: '{amount}$'
start-apply: 0Additionally, you need to set menu.shop.click-update to true if the related to product is also in the menu you opened. Otherwise this price won't auto update after you sell B product.
Dynamic Price per player
As long as you can ensure that the placeholder used in the formula is per player, the calculated price result will naturally be per player. In the above example, we used global placeholders such as {buy-times-server}, and you only need to replace the server with the player to display the player's own buy times value. The relevant content is explained in detail in the Placeholders page.
Set buy / sell limits for your products
Please view Products page for info and example.
Reset dynamic price
Many people ask this question, and I feel that the person asking this question simply does not understand the essence of UltimateShop. The dynamic price is determined by a formula, so you cannot reset the price directly. To reset the price, the variables used in your formula must be reset. If you use variables such as {buy-times-server} exactly as described in this section, they can be reset.
You can reset the buy times or sell times by our auto reset feature, you can find more info at Buy/Sell Times Reset page.
