The FX transaction-cost intelligence platform
Banks price every FX trade off the interbank mid-market rate. The distance between that rate and what you actually paid is the fee nobody shows you. Midarx measures it on every trade, in basis points — and defends the number with an evidentiary chain.
The fee nobody shows you
There is no line item. The cost is folded into the exchange rate you were quoted — a few basis points here, a wider spread on the small or off-hours tickets, a drift that compounds across a year of flow. Midarx reconstructs the mid-market rate for each trade, measures the distance you paid above it, and turns a number you never saw into one you can defend in a negotiation.
How it works
The same pipeline the analysis tool runs — intake to export, every figure traceable to its source.
Upload trade history as CSV, Excel, or pasted bank-confirmation text — the files as you receive them. Columns are resolved and every row is normalized to a canonical currency pair.
Duplicates, implausible rates, spot-vs-forward mismatches, and outsized tickets are flagged against stable rule IDs — surfaced for human review, never silently corrected.
Price against the bundled reference, or bring your own licensed market-data exports — your licensed data never leaves your environment. Sources are cross-reconciled and disagreements flagged.
Load your negotiated pricing agreement. Midarx tests every trade against target spreads and variance bands, and assembles a refund-claim schedule where the bank charged above the agreed rate.
Produce an audit-grade PDF, a monthly exception-led draft, and trend views — markup by provider, currency, ticket size, and month-over-month movement.
Ask questions in plain language and export the normalized dataset. Answers cite the rule, the record, and the source — or say when they can’t.
Who it’s for
For advisory firms
FX advisors, treasury consultants, and bank-fee audit practices run Midarx as their own platform. Your methodology stays yours — it runs only in your tenancy, never in the shared engine — while the deterministic pipeline does the reconciliation work that used to eat analyst days per client.
For mid-market corporates
Upload a sample of your recent trades and see your markup against the mid-market rate — by currency, by ticket size, over time. It’s a preliminary review: a fast, concrete read on what your FX is really costing, positioned as early access to the platform.
DefensibilityPatent pending
A number is only useful in a negotiation if it survives scrutiny. Midarx is engineered so every figure can be independently re-derived, and every inference is on the record.
Every markup, exception, and compliance verdict comes from a rule with a stable ID — the same inputs always produce the same output. No black box.
Where the engine infers — a timezone, a carried-forward reference date — it says so, in the report and in the record, with its rationale attached.
Advisory methodology and client data run only in your tenancy. Nothing crosses into a shared engine or another tenant.
Client data is never used to train shared or public models. It is analyzed, reported, and left in your environment.
Each analysis is committed to a SHA-256 hash chain. Any later change to a record breaks the chain — tampering is evident, not silent.
Use your own licensed intraday exports. They are cross-reconciled against the reference and never leave your environment.
