At the start I want to emphsise: I was focusing most of my ingame time on trading mechanics. It was my main goal in this server run to test it.
- How often do you need to restock? How many times a day?
I tried to restock the machines twice a day. Like every 12 hours (that also depended on my free time i could spent in the game). Normally it took me two runs for each market: once to see what is missing and second - to deliver goods.
- Is the storage capacity enough?
Well, hard to say. On one hand, it could be bigger -> more goods will be stocked. On the other hand, when TS is destroyed, more goods will be lost too. Sometimes i wished to have more display options (in big machine u can set up up to 6 products). So, yes, 4 slots in storage and 2 in display could be useful.
- In trading stations that buy items - how do you control how many of each items you want to buy?
In the current system it is mostly impossible. Mostly because of its simplicity. The only way I see to control my demand is to set every single needed product/resource in separate machine. And control it by amount of coins in each one.
- How many coins do you typically keep in each trading stations?
Like mentioned before, I tried to leave about 30% of my income in the buying machines. So, when after 12 hours I grabbed like 1500 coins, 500 was reinvested. It could change slightly depending on my ongoing needs and prices set for buying. Now I don't keep more than a 1000 coins in every buying machine.
- How do you decide how much of each type of goods to stock?
To use storage space to maximum, stack was my main number. But I had always keep in mind that TS can be destroyed and then I lose what is inside. So all resources were in one stack maximum. Usable items, like bandages, cigars, vodka - up to 5 stacks. Ammo - up to 4 stacks maximum. For unitary items, like hazmat suit, armour, weapon - up to 3 units. For low tier unitary units, like leather armour - up to 5 units each type. Very important! U need to leave one slot in storage free - for coins.
- Do you advertise your services in any way?
Yes, I did. I wanted all players to know about my market. So, almost every time i restocked the machines I gave info about that on global chat with coordinates to the place. And it worked pretty good. But of course it would be nice to have a possiblity for more "agressive" marketing, like banners, TV commercials (when eletricity is introduced). And more building options in area of trading would be good too. Like - "welcome" entries, signboards, etc...
- Do you have regulars? If so - do they leave any feedback to you about your trading stations? Have you made any changes based on their feedback?
U mean returning customers? Yes, I did. And that was the most satisfactory part of that test. People were asking for restocking certain products, or giving me the info what is missing at the moment. And I did adjusted prices of few products based on their feedback. After few days of running the market i noticed that when a new player was asking on chat where to find lithium or plastic, sometimes he got answered like: market, coords, cheap. So, the info was spreading around on itself. And in some way I got respected (I am not boasting myself here now, just giving my expressions). Funny moments: One called me "the king of trade" and one hand love to me

- Would you change anything in the current trading system?
Partially this question is already answered above. Little more storage slots. Little more display slots. More paying options - not only goods for coins, but also goods for goods. Maybe a dedicated landclaim that will make TS area PVE (but still with raiding option). I didn't liked the fact, that when two TS were buildednext to each other, u could freely move between them. That knowledge "costed" me two trading stations. To make them unaccesible from behind to the third party, u need to separate them with wall. And of course statistics.
In one of the future versions we are also going to introduce detailed statistics to make keeping track of your sales easier. Do you have any requests for this or additional features?
Well, I have a master degree in economics and work all my life in trading, so.... some basic statistics could be very helpful. Now i used my memory and a sheet of paper for that. And had no competition - did not have to worry about their prices and stock. More sophisticated solutions will mostly depend on how trading will develop in the future. Options are limitless.
