You describe an economic perpetuum mobile. It is no more realistic than a physical perpetuum mobile.I thought everybody understood all this.
Oh well.
Take the worlds Tammuz and Ascalon in the Solomani Rim, two non-descript high-pop worlds.
Buy trade goods on Tammuz (A-F Im) for kCr 4 [base] -1 [HiPop] -1 [Starport A] +1.5 [TL F] = Cr 3500. Sell on Ascalon (TL E): Cr 5000 + 500 [TL] with a rented Broker-4 and Bribery-2. Sell at an average of 210% = Cr 11550 minus a commision of 27% is Cr 8430. You made a profit of about Cr 5000 / dT every jump.
If you are a megacorp you of course toss in a few megaton bulk-freighters carrying ~770 000 dT cargo at a cost of MCr 850 per jump. 770000 dT × Cr 5000 /dT ≈ MCr 3850, so you make a profit of about GCr 3 / jump. If you jump one ship in each direction every day (using 20 ships or so) you make GCr 3 × 2 = GCr 6 every day or 365 × 6 ≈ TCr 2 every year. Business is booming so you add a few more ships and jump one ship per hour in each direction, the markets magically expand and you now make TCr 48 / year shipping 770000 × 2 × 365 × 24 = 13.5 billion dT goods. You also turn over about 15% of the entire trade volume of the Solomani Rim sector.
You now do the same between Vanefa-Suleiman, Vanefa-Azaremiid, Sulaiman-Azaremiid, and Azaremiid-Al Jabry. Since you need J-2 you can only carry 650000 dT cargo at a cost of MCr 970 / jump, so you only make about GCr 2 / jump or TCr 32 per year for each route or TCr 48 + 4 × 32 = TCr 176 per year. Guaranteed, risk free. In a single subsector you are shipping 770000 × 2 × 365 × 24 + 4 × 650000 × 2 × 365 × 24 = 59 billion dT cargo using 5 × 20 × 24 = 2400 megaton freighters.
But why stop there, lets jump a ship every minute on each route. Again the markets magically expand to swallow everything at the same price, so we now make PCr 10 shipping 3.5 trillion dT cargo / year. Note that our profit is now about the same as the sector's GDP.
Note that we have no in-house broker skill, we bought external services for that. The brokers made about Cr 11550 × 20% = Cr 2310 / dT or about half as much as we did. So the brokers on these 6 systems made about PCr 5, that is much more than the subsector's GDP.
The speculative trade system works for free traders, but does obviously not scale up to megacorp level.
