Philosophy & approach

Most tools force you to pick: either a long-run wealth plan with smooth curves, or a trading terminal with greeks and order tickets. ArcLogic is built for people who need both in the same headspace — the “technician” who sizes lifestyle against capital, then stress-tests how positions behave when volatility and time do not cooperate.

Two engines, one story

We separate concerns on purpose. Engine A answers “what return behavior does my plan need to stay viable?” in largely linear, transparent terms. Engine B answers “how wide is the range of outcomes when returns are not a straight line, and how do my structures behave?” That split keeps strategic hygiene from being drowned in noise, and keeps tactical tools from pretending they replace a savings plan.

Numbers you can interrogate

The models in the app are not black boxes. Baseline maintenance (BMR), spread P/L, Black–Scholes greeks, and the Monte Carlo fan are implemented in shared, documented code (see the Engines and Strategies & lab pages for definitions and units). The goal is judgment with receipts — not a single forecast to believe, but a set of relationships you can test against your own assumptions.

Not advice

ArcLogic is for research, education, and internal discipline. It does not know your full balance sheet, tax picture, or constraints. Use outputs to ask better questions, not as instructions to transact. See our risk & disclosures for the full picture.
