DieselFlow Pro Evergreen: Fuel Supply-Shock, Tanker Tracking and Refinery Margin Toolkit (Lifetime Licence)

Buy once, use for years. Model any fuel supply shock (a supply deal, a sanctions waiver, an export ban, a refinery outage) and keep it current yourself from free public data. No subscription, no updates needed.

DieselFlow Pro Evergreen turns a fuel-market headline into numbers a trading desk can use: which reported cargoes check out, when they could land, how far the volumes could move US diesel prices, whether the arbitrage is open, and what it means for US and European refinery margins. You describe the event once; the dashboard, Excel model and Python engine do the rest.

What you get

• Flow monitor (HTML dashboard). Volume gap, cargo register with five verification levels, voyage map and progress, ETAs, price-impact ranges, crack outlook and arbitrage, in one file that opens in any browser.
• Excel model with 1,370+ live formulas. 12 sheets, including a Keep It Current checklist of every input, how often to refresh it and a free source. Enter up to 12 months of event volumes; positive adds supply, negative removes it. No macros.
• Python engine with 56 tests. One-command price refresh from EIA data via FRED (no API key), scenario files you can switch in one command, sea-lane routing for 11 export ports (Russia, India, Saudi Arabia) and 9 destinations with your own ports addable, planned and live ETAs, optional AIS tracking, supply-shock Monte Carlo, landed cost and netbacks with price-cap checks, and a mean-reverting crack outlook.
• Worked example and templates. The October 2026 US–Russia diesel arrangement (about 4.8 Mt, OFAC General License 135), plus blank templates for a supply deal and a supply disruption.

How it stays current without updates

• NY Harbor ULSD, Brent, WTI and US retail diesel refresh automatically from free public data; diesel cracks are recomputed.
• Exchange prices (NYMEX futures, ICE gasoil), freight and duties are entered by you; the Excel sheet and guide say where to find them.
• A new event is one JSON file or a few Excel cells: volumes, dates and an optional licence deadline.
• About ten minutes a month keeps it fully up to date.

Good to know

• Price effects are scenario ranges from stated assumptions, not price predictions.
• Results are only as current as the inputs you give it. The worked example's market data dates from October 2026.
• Live AIS tracking is optional and uses your own free aisstream.io key; coverage depends on that service.
• Delivered as a downloadable ZIP. Lifetime licence for one organisation, internal use. One-time purchase: no updates, support or data service included or needed.
• Not legal, investment or sanctions advice.

Who it is for: physical and paper distillate traders, refinery economics teams, shipping and chartering analysts, energy-focused funds and research desks.
