Really excited to see improvements on Black Market, great work on this so far! The multiplier based on relative research tier is the biggest selling point for me, the buy/sell differential is also really big.

1) The buy/sell differential is also a little confusing, the "gun" category for example is 135/120? This means guns cost 135% of a base price and sell for 120% of a base price, but is there a reason for not normalizing it to 100? Can these be adjustable, especially as far as disabling an item or category?
2) 3600 is the default refresh interval, 18000 is the max, but changing doesn't seem to affect it, it's always every couple of seconds for me.
3) The combinator method works fine, but I don't understand the difference between a Fill Order and Autobuy, and I don't even really want the option to buy directly to my inventory. Might be some opportunity for streamlining this a la Black Market.
4) Factory vs Player money completely lost me. Money comes and goes, sometimes the factory side would lose money from my sale, and I can transfer between and I have no idea how or why. This made it impossible to tell basic info e.g. what I earned from a sale.
5) I would rather see a Buy Price per Unit and Sell Price per Unit when selecting an item, rather than Price per Unit and Price per Second for buy or sell side depending on which box I was in.

This is awesome work, like I said before I'm extremely excited to find this and I hope it does really well. Other than the above issues everything worked great, keep up the great work and thanks.

Hi there!

Well .. it's not black market. ITC has been programmed totally independently from black market since there were some problems with data structure in black market which didn't support some features included in ITC. The multipliers are fully independent from research tiers and only scales up with time necessary to create a product. The paygap + enhanced prices on finished goods should emphasize long production chains with finished products at the end.

For your list:
1) Basically it means that if you really really want a shotgun you either pay more if you do not produce it by yourself while also being preferred as a selling good. If you look into the control file you can see those values somewhere at the top. You can change them as you prefer. If you set them to 0 they should be disabled in the process.
2) It doesn't seem to affect it, since this option is opted for hugely modded saves where calculations may be quite heavy. You see, there is some variable calculation system where a list is being processed and there will at least be one entry that is read every tick. So for very small (vanilla-y) lists, there will be little to no difference.
3) So the basic difference betweem the two is that auto-buy is for your private needs while the fill order is solely for chests. Yes, in the beginning you will buy/sell a lot of things through your inventory but in the late-game it will be a little portion of your trading. If you don't want to use it, simply feel free to do so!
4) The difference of the factory money shows the total amount of money being transferred. So basically things get sold from chests, then buys from chests are being processed. Occasionally this will result in negative differences, which should totally be fine in the long run. Sometimes you will hit that timing where you sold something from your inventory and it will directly be used for buying things to chests. Totally fine, as said. There is also a window to look into buys and sells when you click on the book in the ITC menu. Please note, that this features is also under development and entries are not being summed up yet nor show any time stamp.
5) :) ... it's not a price per second but a price per stack (hold) number. Like if you hold 5 iron plates the /s price will show five times the price of an iron plate if you sell it. It is solely for quick-sell information purposes since there is no way to actively buy items from a cleared gui. If you would like such a feature, I will include it into my notes. When time will come again, I will process all requests.

Thank you for your extensive feedback so far. I wished there were more people putting such work into giving feedback.
Cheers!
