Test Your Trading Strategy Across 4 Hidden Market Regimes
One backtest shows how your rules did in one kind of market. Run them through a gap, a crash, a war trend and a whipsaw, blind, and find out if the edge is real.
Same rules. Different market.
A strategy backtested on the months that inspired it will always look good. The edge you measured belonged to that market, not to your rules.
The backtest most traders run: one trending stretch, a beautiful curve.

Four shocks and a range
Named here, hidden in the app. Each one breaks a different part of a strategy.
You can't game a market you can't date
Recognise the date and you know what happens next. So in validation the chart shows only the weekday and time, and each event's name appears once you pass it.
The date gives the answer away.
Weekday and time only. You trade the price, not the headline.
One session. Every regime.

Testing a strategy across market regimes
What is a trading strategy test across market regimes?
It is a backtest that deliberately runs the same rules through several very different kinds of market instead of one convenient stretch of history. A market regime is the character of price over a period: trending, ranging, crashing, gapping on a shock, or whipsawing on headlines. A strategy that only ever saw one regime has not been tested, it has been fitted. FxBacktest runs your strategy through four historical shocks and an optional ranging market and marks each one validated once it has enough trades and enough replay behind it.
Why are the events hidden while I trade?
Because knowing the date is knowing the future. If you recognise the day a famous crash started, you already know which way to trade it, and the test measures your memory instead of your rules. While a validation session runs, the chart shows only the weekday and the time, the jump-to-date controls are hidden, and the events appear as Event 1 to Event 4. Each name is revealed only once that event is validated.
How many trades do I need per event?
100 trades on M1 to H1, or 30 trades on H4 and above, entered between the start of the event and the start of the next one. The replay also has to run at least 30 days past the event's start, so a burst of trades in the first afternoon does not count as surviving the regime.
Which markets can I validate on?
Gold (XAU/USD), the Nasdaq 100 (US100), EUR/USD and GBP/USD. All four carry price history back to the oldest event, including minute data. Existing sessions on other instruments are listed too, as long as their history reaches the event.
Do I need a separate backtest for every event?
No. One session collects all of them. When an event is validated, a banner on the chart reveals which event it was and offers to jump the same session to the next one. Your trades and balance carry over, and each event only counts the trades taken inside it, so the report shows the return for every period separately.
Is strategy validation free?
The free plan can validate one event per session, on M15 and above. Pro raises the limit to 600 trades per session, enough for all four events plus the optional ranging market in a single session. Minute data (M1 to M5) that old is part of Ultra.
What is the optional ranging market test?
A fifth, recommended event: the tightest 30-day range on your market since 2016, measured as the window's high-low range against its average daily range. Shocks test whether a strategy survives violence. The range tests whether it survives boredom, which is where most trend-following systems quietly bleed.
A trading strategy test is only as honest as the market it runs on. Backtesting rules on one recent stretch mostly measures how well they fit that stretch, which is why so many strategies fall apart within weeks of going live. Testing across market regimes asks a better question: where does the strategy stop working? Sample size matters as much as variety, and the measured sampling error of a backtest shows why 100 trades per regime is the floor, while how long 100 backtested trades takes breaks the time down by timeframe.
