Whatever you trade, the news moves it. Know how much — and what it costs.
Impact measures what actually happened after every economic release: how far each instrument moved, second by second, and what the spread did at the moment the number printed. Across FX, metals, oil, indices and crypto.

The problem
The calendar tells you the number. It doesn't tell you what it did to your book.
Every calendar shows you that CPI is at 13:30 and what the forecast is. None of them tell you how far your instrument actually moved when it printed, how long the move lasted, or what your spread looked like at that exact second — which is often the difference between a trade that works and one that doesn't.
If you hold risk through economic releases — and almost everyone does, whether they trade the news or not — that's the information you're missing.
What nobody else shows you
What the spread did at the moment it printed
Impact records spreads continuously across a panel of more than 250 brokers, so for any release you can compare the normal spread against the spread at news time. A move you can't afford to trade isn't an opportunity.
| Instrument | Normal spread (median) | At news time (median) | Change |
|---|---|---|---|
| EURUSD | 2 | 6 | 3.0× |
| USDJPY | 3 | 11 | 3.7× |
| GBPUSD | 3 | 8 | 2.7× |
| XAUUSD (gold) | 16 | 100 | 6.3× |
| US 30 index | 12 | 125 | 10.4× |
| BTCUSD | 236 | 5,401 | 22.9× |

What you get
Three things, for every release we track
The move, second by second
A chart per affected instrument, marked at the exact release time, down to one-second resolution — plus tick-level bid and ask when you need to see inside the move.
The cost of trading it
Normal spread against spread at news time, measured across 250+ brokers, with the share of accounts trading at or below the median. The honest answer to whether a release was tradeable.
The size of the surprise
Forecast, actual, prior and revision — with the deviation calculated for you, on both the headline figure and the revision. The surprise is what moves the market.
Coverage
Not just FX
A single US CPI release renders around thirty instruments. Economic data moves everything, so Impact measures everything it moves.
- FX majors and crosses — plus a deep exotics book: TRY, ZAR, MXN, PLN, SEK, NOK, CZK, HUF, SGD, CNH
- Indices — US 30, US 500, DAX and more
- Metals — gold and silver
- Energy — oil
- Crypto — BTC and ETH, which now react to US macro like everything else
1,773 event types, 22 countries
From Non-Farm Payrolls and CPI to rate decisions, PMIs, inventories and regional releases — roughly twenty a day, scheduled ahead and measured afterwards.
Every release is timestamped against when the data actually reached us, so you can see the delivery latency rather than take it on trust.
Who it's for
Professional traders who carry risk through events
Discretionary traders
Know what's coming, how far it typically moves your instrument, and whether the spread makes it worth touching.
Systematic and quant desks
Event-aware sizing and blackout windows, built on measured reaction distributions rather than assumptions.
Prop-firm traders
Drawdown limits make event risk existential. Being caught by a release you didn't know was coming can end an account.
Execution and risk
Spread at news time across a 250-broker panel is a cost-of-trading and best-execution question, measured rather than estimated.
How the data is built
Measured, not modelled
Price data comes from an institutional feed and is stored at tick and second resolution. Spread data is recorded continuously by our own software across a panel of more than 250 brokers. Release figures are collected from primary calendars and timestamped on arrival.
Impact is a post-event analysis tool, not a live feed. Charts for a release become available roughly ten minutes after it prints, and the data is historical rather than streaming. We would rather tell you that up front than have you find out after you've paid.
Impact reports what happened. It does not tell you what to trade, offer recommendations, or make any claim about returns.

Questions
Before you sign up
Is this a live feed?
No. Impact is a post-event analysis tool. Charts for a release become available about ten minutes after it prints. If you need sub-second live execution data, this isn't that product.
Do you tell me what to trade?
No. Impact measures and reports what happened — price moves and spread costs. It gives no recommendations, signals or advice, and makes no claims about returns. What you do with the data is entirely your decision.
Where does the spread data come from?
Our own software records spreads continuously across a panel of more than 250 brokers. "Normal spread" is the observed median across that panel; "spread at news time" is what was observed at the moment of the release.
How far back does the history go?
Release data goes back to 2001, covering 97,428 releases across 1,773 event types and 22 countries. Reaction chart depth varies by instrument.
What happens after the trial?
The 7-day trial is free. If you continue, it's $249 per user per month, billed monthly, cancellable at any time. You're also covered by a 30-day money-back guarantee after your first payment.
Does it work on a phone?
Impact is built for desktop — the reaction charts and spread tables need the screen space. It's best used at 1920×1080 or similar.
Who is behind Impact?
Impact is operated by Dostum Amigo SL, a company registered in Spain. The underlying market data infrastructure has been run for over a decade by a specialist FX technology team.
