Trading against a defect in FPT's pricing, market data, fill simulation, balance calculation or dashboard is prohibited. If you find one, stop trading on it and report it — reporting is never penalised.
This rule is narrow on purpose. It is not about strategies FPT dislikes, and it is not about trading fast. It is about profit that comes from the platform being wrong rather than from the market being read correctly.
What Counts as Exploitation
- Acting on a stale, frozen or visibly incorrect price — a quote that has not moved while the underlying market clearly has, or a price that is obviously outside the market's real range.
- Exploiting a latency gap between FPT's simulated market view and the underlying market, including entering after an outcome is effectively known but before the platform's view updates.
- Routing size through a market chosen because a figure is malfunctioning — a broken 24-hour volume number that unlocks a larger position than the real 5% cap would allow, a wrong liquidity reading, or an incorrect resolution status.
- Trading a market whose balance, drawdown or objective calculation you know is misreporting in your favour.
- Repeatedly probing the platform — placing orders you do not want, in markets you have no view on, to locate a defect of any of the kinds above.
- Using automation to do any of the above, to place orders faster than the intended interface allows, or to evade a position limit.
The test is knowledge and intent together with effect. A trader who has spotted that a price is broken and sizes into it is exploiting it, whatever the strategy is called.
What Does Not Count
FPT is not trying to outlaw ordinary skill. None of the following is a breach:
| Activity | Status |
|---|---|
| Reacting quickly to real news in a real market | Permitted |
| Trading a market that is mispriced by other participants | Permitted |
| Taking a view that a market's implied probability is wrong | Permitted |
| Trading around a scheduled event, data release or resolution | Permitted |
| Using tools, spreadsheets, models or alerts to inform your own decisions | Permitted |
| Sizing into a price you believe is stale on FPT's side | Prohibited |
| Automating orders to beat the platform's intended interface | Prohibited |
A mispriced market is the whole reason prediction markets exist. A mispriced platform is a bug.
Simulated Fills Are Not a Stale-Price Guarantee
FPT accounts are simulated. Fills consider live market price and available liquidity, and FPT does not promise a fill at a stale price. Any estimated slippage or price impact shown before you commit is an estimate and is not guaranteed.
This has a direct strategic consequence: a strategy whose entire return depends on the estimate being wrong in your favour is not a viable strategy on FPT, and building one deliberately falls under this rule. Detail is in How Simulated Fills Are Determined and Estimated Slippage and Price Impact.
The same logic sits behind the 5% market-volume cap. A position that is large relative to a market's real trailing 24-hour volume could not fill at the screen price in the underlying market, so FPT will not let a simulated account pretend otherwise. See Max Open Size and Market-Volume Limits.
Markets Depend on Third-Party Data
FPT's market view is built from third-party prediction-market data. Feeds go down, resolve late, correct themselves and occasionally publish something wrong. FPT is not affiliated with, sponsored by or endorsed by Polymarket or Kalshi, and cannot guarantee the accuracy or availability of their data.
Where a market's data is unreliable, FPT may restrict or suspend trading in it. That is a protective action, not a penalty. See Market Resolution and Data Dependencies and Temporary Market Restrictions.
Systems Integrity
Separately from trading conduct, it is prohibited to attempt to access, probe, reverse-engineer, overload or interfere with FPT systems, other customers' accounts, or the platform's protective controls. That includes scraping beyond ordinary use, attempting to bypass an order block, and testing the platform's limits by trying to break them.
How to Report a Defect
- Stop trading on it immediately. Close or leave the position alone; do not add to it.
- Note the market, the approximate time, what you saw, and what you expected to see.
- Take a screenshot if you can.
- Email support@fundedpredictiontrader.com with "platform defect" in the subject line.
- Do not post the details publicly before FPT has had a chance to fix it.
Reporting a defect is never penalised. FPT would rather pay for a bug report than pay out on one. A trader who reports promptly and stops trading is treated as having complied with this article, even if a position was already open when the defect appeared.
What Happens If Exploitation Is Established
Proportionately to the conduct, FPT may void the affected trades or the affected result, deny a payout, reset, suspend or close the account, close related accounts, and terminate the program relationship. A discretionary refund is not available after an account-rule violation.
FPT applies the least severe response that addresses the conduct. A trader who happened to be on the right side of a bad tick once, and who did not press it, is not treated as an exploiter. A trader who found the tick and repeated it is.
The review sequence, the notice you receive and the appeal route are in Rule Violations and the Review Process. The binding conduct rule is Good-Faith Trading and Prohibited Conduct.
Still Need Help?
If you are not sure whether an edge you have found is a market inefficiency or a platform defect, treat it as a defect and ask. Email support@fundedpredictiontrader.com with the specifics before you trade it further.
