- Four cards: chance-pass rate, detection limit, rank, countdown.
- All computation stays in the browser.
How to use Tape Check on the website.
Getting in
- Choose file – trade export (CSV) from your journal or platform. The header row is read automatically.
- Paste table – copy a table from a spreadsheet; tab or comma separated.
- Example trader – one built-in example trader (fictional) to try it out.
On the Tape Check page you can also open How to read the numbers below the app.
What you enter
| Input | Required | Notes |
|---|---|---|
| Trades (result per trade and trading day) | yes | Result in R when possible; otherwise derived from money result and risk per trade. |
| Cost per trade | yes | Commission, fees, slippage – you enter the number; we do not guess. |
| Account rules (target, max loss, floor type, daily limit) | optional template | Generic template; no firm presets. |
| MAE / MFE per trade | optional | With MAE and MFE we bound the path. Exact computation for stop/target brackets; for other exits, assumption and span. |
Before computing you see what was recognised (trade count, contracts, total).
Reading the result
Four cards:
- Chance-pass rate – of 100 traders with no edge, how many pass with your rules and costs.
- Detection limit – smallest edge per trade your sample could detect with 80 % probability at your trade count.
- Rank – where you sit among simulated no-edge traders. Rank is not the probability that you have skill.
- Countdown – roughly how many more trades you need before an edge of 0.10 R per trade would be measurable (planning value, preliminary rule set).
Plus “Save receipt”: the proof receipt is stored as a file on your device.
Planned after the beta: edge band (from 150 trades), verdict levels, stamped forecast, sharing as a card.
Limits
- Figures depend on the rules and trade shape you enter; they are not statements about any firm or real pass rates.
- Without MAE/MFE, trailing-floor chance-pass rates can be overstated; the UI then shows a range.
- Planned: below 20 trading days the rank will be marked uncertain. The beta does not show this yet; with so few days the rank is very uncertain.
- No signals, no buy recommendations, no firm names.
Privacy in short
On the web, trades are computed in your browser; the trade file is not sent to us for analysis. Details: Privacy.

Why no firm names?
The rule templates in Tape Check are neutral example values you adjust. You can enter your own rules. We are not tied to any firm and we do not earn money from evaluations run by other providers.
This page is the user guide. It does not add promises beyond what the app and the Privacy page already say.
