I find several dramatic inaccuracies/drawbacks in the current trade system.

1. Impossibility to stockpile resources. It is a common fact that production and consumption of resources varies greatly depending on construction projects needs and front line situation. For example, we may be focused on Navy buildup and need steel in huge quantities, but afterwards we plan to concentrate on Air Force. That is going to require aluminium, which we may not be able to trade for, because we are embargoed by that time (recall Germany, that had to buy almost all rare materials from USSR and all oil from Romania and Hungary after being embargoed and blockaded by British and French). This mechanic eliminates strategic materiel reserves as such. In real life it is virtually impossible to conduct economic life without resource stockpiles in peacetime, not to mention time of war.
Where is Germany/Italy going to get Aluminium after declaring war on Allies/Comintern? Where are we going to get natural rubber?
Historically, governments had huge influence on international trade focus, especially considering strategic resources. In the case of dictatorships like Axis powers and USSR (which had absolute state run economy and no trade deals, I repeat, not a single deal was ever struck as a private venture) regulation was nearly absolute.
And even if we somehow manage to trade through blockade as Germany, for example, AI having controls of convoys is going to drain our merchant Navy to naught. Germany is going to lose all (every single) merchant ship to British Grand fleet blockade within a month, at best. This system is absolutely unrealistic and not representative of the real WWII event line.

2. Inability of stockpiling oil/fuel/food is going to make strategic buildup and strategic military operations impossible. For example, we are mobilised and are preparing to launch Blitzkrieg into Poland as Germany. On the last day of August our fuel/oil consumption is going to be average, but immediately after hostilities commence, we are going to need unheard of amounts of fuel/ammo for our tanks/ships/planes. It is simply impossible to have industry/trade cover such a raise in demand in such a short time and keep the supply line rolling. We shall have no fuel within day. NO MORE BLITZ for "ze Germans". We shall have to get horses to tow tanks and give Bismark sails to sortie into the Atlantic...Uboats going to be powered by muscle power through bicycle drives :p?

3. Industrial production of weapons, especially heavy ones, is going to require large amounts of materials, that are simply impossible to trade for immediately and keep them coming, unless you're USSR/USA/GB and have unlimited supplies. Simply put, if we are Germany/Italy/Swededn/Finland etc, we shall first need to gather metal/rare materials/rubber needed to produce our ships/tanks/planes, before we can actually start construction. Otherwise, we're agoing to "enjoy" 100% construction penalties for our projects.

Now, lets consider some examples.

A) Nickel, tungsten are vital rare materials for armor/artillery/ammunition construction. Germany had stockpiled those for they had nowhere to buy them from. By 1944 they completely ran out. Germans HAD to use their uranium for armour piercing ammunition instead of tungsten and lower amount of nickel in their tank armour alloy. German nuclear program was effectively ruined by that (and, please, don't say it was all because of Norwegian resistance and their little heavy water plant venture). Read Albert Speer and see what he had to say about Germany's strategic resources and war effort.

B) Oil/fuel demand in time of war DOES NOT depend on on its production. It ONLY depends on military NECESSITY. We cannot forsee exact amount of fuel necessary to be produced and delivered, but rather we need a certain amount of ready to use fuel stockpile, that we can take from without having to wait to trade for oil or make synthetic fuel.
During D-Day invasion allies unloaded millions of tonnes of fuel into Normandy bridgehead and even built a fuel line across the English Channel in order to have it ready for use, because refineries simply cannon produce such amounts of fuel as needed for combat in a day and have it delivered instantly.

C) It is a well known fact that during the war Germany was dependent on iron ore from Sweden for its heavy weapons. But it isn't a well known fact that German Navy (Kriegsmarine) ordered and accumulated relatively large numbers of highest grade armour plates and sheet steel for its warship construction programs BEFORE the war. German shipbuilding and even tank production ran on those long after hostilities broke out. Without those stockpiles there would have been no Uboat construction program for Doenitz and no Elephant tank destroyers :p

D) To show that even USA could find a way around supply stock pile, lets take a look at their nuclear project. USA had to conduct geologic recon, build mines and start mining for uranium ore long before theoretical nuke was ready and even long before uranium ore processing plant in Tennessee was ready. Otherwise, it would have taken years longer to have the bomb ready. Perhaps, we're not going to have uranium as a resource in our game, but example itself shows that even nations as USA HAD to stock pile.

To conclude it, I'd like to say that present economical/trade mechanic is not viable and does not even remotely represent trade/economic system that actually took place during WW2.

Dear developers, please, be so kind to reconsider trade/resource/economic mechanics and, perhaps, affect changes into the game, so that we (buyers/gamers) could have a fun and accurate game on release.

P.S. If anyone is interested in resource trade numbers during WWII, I could either start a thread or provide some references to read about it.

Thanks.

The notion of "No stockpile. It is assumed your factories are consuming 100% of what there is." is unrealistic and won't work with any supply system. What if we dont have enough factories to handle our metal or we cant trade the surplus away, or we're are busy making infantry and don't even have necessity or technology to make large warships or tanks. Our factories maybe busy working on other projects, so why not save metal for when we need to make tanks later on?

Agree that trade was way to easy in HOI3 - no trouble to get 99999 of everything before the war starts as Germany. And what was strange, it was easier the harder difficulty you choose because AI had more resources to sell...

And when war starts, you still have resources traded from Soviet, I usually break the trades with the US at that point, but nevertheless, I might go a few short of "rare materials" but nothing serious.

But stockpiles would still be good, but not the amounts that where in HOI3. It was just to easy to have everything. From time to time I chose AI trade - but the AI also did it's job quite nicely - except for trading with countries that you would need convoys for. I have never experienced being out of any resource in HOI3.
One factor you overlook by doing AI trade is that by micro management trade you can get 200 relation level with a lot of countries and attract them towards your faction.
Having Brazil, Spain, Portugal and Persia in your Faction (but not in the war) means strategic naval bases for your subs keeping the British occupied so Italy can win the Med.

When the supply DD comes out i am almost sure fuel is merged with regular supply produced by the civilian factories.

The non stockpile rule is not really based on history (like many things in HOI4). The main reason for it is to make strategic warfare more decisive. Stockpilling still exist but now you stockpile equipment not resources.

You can decide who to import from but not who to export to (which is the importers problem since it's their convoys being used).
Not sure what you mean with automatic trading.

Even if convoys are the importers problem, you will automatically export valuable ressources to a potential foe.

Yes, it will be embargoed if you are at war, but still you will give your future ennemies the means to build the weapons that will destroy you later until the day they declare war on you ?!

Sockpiling equipment, unless you're ready to use it is a waste of IC. You'll have to make tanks in 1936 to "save" your IC and then send them back in 1938 and make new ones and use IC 2 times over just to preserve resources. Instead, just make ships all the way :p and only a few tanks to gain production bonus later. This is way too gamey for HoI franchise.

This resource system actually sounds really good. Stockpiles were kind of a buffer, and this system seems to represent that in a way. Even if you lack in inflow, you have some production efficiency (unless, as stated, lacking all resources) meaning you take from the abstract national stockpile. I guess it would have been cool to have a shared gradual efficiency loss curve for all related prod. lines when lacking, but this sounds like a perfectly fine system.

The trade system likewise seems nice, countering hind-sight effectively while being reasonably historically representative. The hoi3 trading was a serious exercise in boring.

I find several dramatic inaccuracies/drawbacks in the current trade system.

1. Impossibility to stockpile resources. It is a common fact that production and consumption of resources varies greatly depending on construction projects needs and front line situation. This mechanic eliminates strategic materiel reserves as such. In real life it is virtually impossible to conduct economic life without resource stockpiles in peacetime, not to mention time of war.

So how big of stockpiles do you think there was? Maybe do some historical research but be prepared for a shock.

Where is Germany/Italy going to get Aluminium after declaring war on Allies/Comintern? Where are we going to get natural rubber?
Maybe the same place that almost all countries got their rubber during WW2 from. Synthetic.

This system is absolutely unrealistic and not representative of the real WWII event line.
What is unrealistic is you knowing that WW2 will happen. This corrects for that.

2. Inability of stockpiling oil/fuel/food is going to make strategic buildup and strategic military operations impossible. For example, we are mobilised and are preparing to launch Blitzkrieg into Poland as Germany.
That falls under supply. Wrong topic there.

3. Industrial production of weapons, especially heavy ones, is going to require large amounts of materials, that are simply impossible to trade for immediately and keep them coming, unless you're USSR/USA/GB and have unlimited supplies. Simply put, if we are Germany/Italy/Swededn/Finland etc, we shall first need to gather metal/rare materials/rubber needed to produce our ships/tanks/planes, before we can actually start construction. Otherwise, we're agoing to "enjoy" 100% construction penalties for our projects.
You keep saying things like this but it doesn't match history. Germany produced way more after the war started despite all these things you claim they didn't get.

A) Nickel, tungsten are vital rare materials for armor/artillery/ammunition construction. Germany had stockpiled those for they had nowhere to buy them from.
Once again do some research. Try Portugal as the German supplier for tungsten. And the lack of tungsten resulted in different types of shells and anti-tank weapons, I.E. shaped-charged.

B) Oil/fuel demand in time of war DOES NOT depend on on its production. It ONLY depends on military NECESSITY.
Fuel is supply so once again wrong topic.

C) It is a well known fact that during the war Germany was dependent on iron ore from Sweden for its heavy weapons. But it isn't a well known fact that German Navy (Kriegsmarine) ordered and accumulated relatively large numbers of highest grade armour plates and sheet steel for its warship construction programs BEFORE the war.
Maybe because most of the German navy was built BEFORE the war. The keels were already laid and most ships were well along in construction.

Most of this post was so far off of historic reality that it's actually funny. Provide us with how many days supply Germany had stockpiled during August 1939 and they KNEW war was starting very soon. After doing the research you will find that the majority of your post is simply inaccurate and flat out wrong.

There is no interaction with coal? Coal was huge back then as it determined te overall production of the factories, railroads etc.
For Germany it was also a source of Oil (maybe this is integrated?) and it was an important export product.
Did you guys just lave it out because of simplicity?

Screens look good btw!

Good point. Coal was primary source of energy for all industrial nations, even though it was phased out from military ship propulsion systems. Coal meant energy for factories and oil substitute fuels. Coal is a must in HoI4, espeacially for Axis powers, since it was about the only resource they had sufficient amounts of.

P.S. If some one doesnt agree that coal was main energy source during WW2, please, provide you opinion of what was the main energy source.

You'll have to make tanks in 1936 to "save" your IC and then send them back in 1938 and make new ones and use IC 2 times over just to preserve resources.
You can't send tanks or other equipment "back", by which I assume you mean scrap them to re-use the resources, or put new armour/guns on them. You can't upgrade a tank which is already produced. You can only produce new tanks to replace the old ones, which then go into your stockpile. You could then re-issue the old equipment to second rate units.

Good point. Coal was primary source of energy for all industrial nations, even though it was phased out from military ship propulsion systems. Coal meant energy for factories and oil substitute fuels. Coal is a must in HoI4, espeacially for Axis powers, since it was about the only resource they had sufficient amounts of.

As Podcat so eloquently said. Socks are a must but everyone had socks. Everyone had coal so its really dumb to include something that you don't need to worry about. Should we also include hydro-electric dams for energy?

they have the same end value, so end up being allowed to buy 50% of the exports. if there was no competition and only one buyer they could buy 100%, but with this particular competition case they are guaranteed 50% at least.

Okay, let me make sure I understand it all.

If only one country is buying the resource, they get to buy 100% unless there is an embargo in place preventing it. (They don't have to buy 100% of it, but they can.)

The moment another country wants to buy, the trade relations mechanic comes into play. Now you have to compete with someone for the resources based on the formula provided.

The longer trade is in place, the more impact relations/influence has on how much you can buy.

So, would I be correct in assuming that it is to your advantage, as a player, to get your grubby little trade fingers into as many trade pies as possible, as early as possible, to start building influence. Furthermore, countries with economic clout like the US can "buy up" extra resources, like Tungsten from Portugal for years on end, to counter Axis influence even if the US doesn't need the tungsten.

Does this mean that the US may have to make some choices regarding their wartime economy? As in, keeping some extra civilian production in play to buy up extra resources if only to deny them to the enemy (or force the Axis to attack neutrals she otherwise wouldn't want to attack)?

A mining company doesn't normaly mine as much ore as they possibly can.
There are simple rules of demand and supply.
You produce the quantity you expect to sell.
If demand is low you decrease the production.
The idea of builing up stockpiles as large as the total demand for years to come is not realistic at all.

Yes but apparently from the numbers he used its a minor impact. It helps but simply being the wrong type of government is a bigger impact. Putting troops or ships near the country is an influence. So unlike HOI3 I doubt if you can get that big of an impact.

Finally it's proportional. Even if US did that and got to say 200 relations (max??) that doesn't mean Germany is cut off. If Germany gets to 200 then they get 50%.

Now here's the great little gem that is hidden. If the US has excess capacity then why not buy up some strategic stuff? They did exactly that in WW2. Of course it's an opportunity issue. Using that CIC for trades means you can't build things with it. And heres the other kicker. USA has to trade away some of their resources unless they embargoed you. So they buy from Portugal but you buy from the USA till they are at war!

Even if convoys are the importers problem, you will automatically export valuable ressources to a potential foe.

Yes, it will be embargoed if you are at war, but still you will give your future ennemies the means to build the weapons that will destroy you later until the day they declare war on you ?!

You mean like the Germans and Soviets?

You do know that the German workers on the Lutzow were still in place as the war began. And Lutzow was part of the trade agreements negotiated between the two countries. (The Soviets, apparently, let the workers go.)

There were German ships laden with resources leaving Soviet harbors the day before Barbrossa began.

Given how important the trade agreements between Germany and the Soviet Union were to the war (they weren't small), I'd say that the system seems realistic even in hindsight.
