How it works
Replay the market, read the numbers behind your trades, find out what to adjust. Three steps, one app.
01TestReplay
Jump from M15 to H4 whenever you like: you only see the candles you have already replayed. The future stays hidden on every timeframe.
When you close, add notes, tags, your strategy checklist and chart screenshots. When you read it back, you will know why you took it.
Set a profit target, daily and max drawdown, and trade under the same rules. Find out whether you would pass before you pay for it.
Paste the code and a developer converts it by hand for the replay chart. Backtest with the indicators you actually trade.
Draw a Long or Short position and it becomes a real order. Drag entry, stop and target, choose how much to risk and close in parts.
Misread the move? Rewind up to 50 candles without leaving the session and redo the read, not the whole day.
The details: manual backtesting, Pine Script® conversion and how to backtest a prop firm challenge.
02AnalyzeStatistics
Win rate, profit factor, expectancy and equity curve on a single screen. The short answer, before the detail.
See whether you win often or win big, and whether your risk stays steady. So you know what to keep the same.
Drawdown, recovery time and winning and losing streaks. See how much a bad run can hurt, before you live through it.
Results split by pair, direction, weekday, hour, session and tag. Find what makes you money and what to cut.
The same trades reshuffled a thousand times in a different order. See the unlucky, the likely and the lucky outcome.
Read every number in R, percent, money or pips. And when you have too few trades to trust it, it tells you plainly.
Trading live too? There's also a plain manual trading journal: separate from your backtests, same statistics engine.
Every metric is listed on the trading statistics page, and the sample size calculator shows when a win rate starts to mean something.
03ImproveFlow Coach
Hours, pairs, direction, risk and checklist discipline. Flow Coach looks at every side of how you trade and finds what you cannot see on your own.
A pattern makes the report only when there are enough trades to believe it. Coincidences stay out.
The report only quotes figures measured on your trades, and you can see where each one comes from. No invented numbers.
What works, what costs you, the pattern worth digging into and what changed since the last report. A few minutes to read.
The first one arrives at 35 trades, the next ones as you add more. Compare them to see whether you are really improving.
Flow Coach works only on the numbers of your trades.
Why sample size decides what a report can say: how many trades you need to backtest a strategy. When live results drift from the backtest: why backtests don't match live trading.
The Flow Report describes the trades you recorded. It isn't financial advice and says nothing about future results.

FAQ
A browser app for manual backtesting on historical data, with a journal for your live trades and one statistics engine for both. You replay the chart, trade it by hand and read the numbers.
No. You place every trade yourself on a real chart. Pine Script® indicator requests are optional, on the Max plan, and converted by hand.
There's a free plan, and you don't need a card to start.
No, on purpose. Backtest and journal are separate tools with their own history, statistics and Flow Coach reports: one measures the strategy, the other your execution.
Historical OHLC candles per instrument; each instrument shows the date its history starts. There is no tick data.
On the paid plans, you set a profit target, daily and max drawdown as % of the starting balance. Limits are checked on equity; the daily one resets at 00:00 UTC of the chart clock; the first pass or fail is locked. It's a simulation, not affiliated with any prop firm.
A numeric summary of your metrics. Note text and screenshots are never sent.
No broker or MetaTrader import, no multi-chart layouts, no tick or seconds data, no automated strategies.
