Advanced Trade Rules in Lightman's Currency: Price Fluctuation, Daily Trades, Whitelists, and Free Samples
Advanced trade rules in Lightman's Currency let you shape how customers interact with your trades over time. Instead of every trade behaving the same way forever, you can make prices drift, gate trades behind waiting periods, restrict who is allowed to trade, and hand out a limited number of free items. This guide covers four of those rules: price fluctuation, daily trade progression, whitelist/blacklist, and free sample.
Price Fluctuation
The price fluctuation rule makes a trade's cost shift randomly rather than staying fixed at its base value. It takes two inputs.
- The first input is a percentage. This sets how far the price is allowed to vary from the base price when the rule applies its change.
- The second input is a time input. This controls how frequently the price is randomly recalculated.
Together, these two settings decide both the size of the swing and how often a new price appears. A larger percentage means bigger deviations from the base price, while the time input governs the rhythm of the changes.
Daily Trade Progression
The daily trade progression rule locks trades in a sequence so a customer cannot simply jump to the last one. Each trade becomes available only after the previous one has been interacted with and the required wait has passed.
- The rule has a time input that defines the waiting period between sequential trades.
- The default value is one day, matching the rule's name.
- You can customize this wait. The shortest allowed setting is one minute, and the longest is thirty days.
When this rule is applied to a group of trades, only the first trade in the sequence is open at the start. Every trade after the first stays locked until the customer interacts with it. The mod also gives alerts that tell the customer how much time remains before they can use the next trade in line. An example setup with four trades shows how this plays out: the customer works through them one at a time, waiting out the configured interval between each step.
Whitelist/Blacklist
The whitelist/blacklist rule controls which players are permitted to use a trade. Its main input is a mode toggle at the very top of the rule's settings.
- In whitelist mode, only players who appear on the list are allowed to trade.
- In blacklist mode, players who appear on the list are denied, and everyone else is allowed.
Switching the toggle flips the rule between these two behaviors, so the same list of names can either grant access or block it depending on the mode you choose.
Free Sample
The free sample rule lets customers claim a set number of items at no cost before the rule stops applying to them. Its inputs are basic and mostly self-explanatory.
- The text box in the top-left corner defines how many free samples a customer may claim.
- Once that limit is reached, the rule no longer applies to that customer.
This gives you a way to offer a taste of a trade without letting it be claimed indefinitely.
Putting the Rules Together
Each of these rules addresses a different concern. Price fluctuation keeps costs moving. Daily trade progression paces a sequence of trades over time. Whitelist/blacklist decides who gets access at all. Free sample provides a capped giveaway. Because the rules are configured through their own inputs, you can combine the ones that fit your setup and adjust each one to match how you want your trades to behave.
