A FundingPips trader says a stop loss intended to cap risk at roughly 0.5% turned into a much larger loss during a high-impact news event, automatically breaching a profitable $50,000 account.
The October 4 complaint, posted on Trustpilot, alleges that the trader had a $50,000 “experiment” account with a 1% daily-loss threshold and was approximately $3,000 in profit before the incident.
According to the reviewer, the same trade was open with another proprietary trading firm at the time. The other firm allegedly closed the position for a loss of approximately $540, while FundingPips recorded a loss of roughly $1,800.
The trader said the FundingPips execution pushed the account beyond its daily drawdown limit and resulted in account closure. They said support attributed the outcome to slippage.
The allegation has not been independently verified. The reviewer did not publish the instrument, entry price, stop price, execution price, order ID, exact timestamp or tick data required to reconstruct the fill.
There is also an important numerical inconsistency in the complaint: $1,800 represents 3.6% of a $50,000 account, not the 1.8% stated by the reviewer. Likewise, $540 would equal 1.08% of $50,000 rather than 0.54%. The second trade may have been held on a different account size, but that is not specified.
FundingPips Explicitly Warns That Stops Can Slip During News
The existence of slippage itself would not conflict with FundingPips’ published trading mechanics.
In its official execution documentation, FundingPips explains that a stop loss is not a guarantee of the final execution price. During major news releases or periods of low liquidity, the market can move through the stop level before an order can be filled.
The company describes negative slippage as execution at a worse price than expected and says it becomes more common around news releases, weekend reopenings and other periods of extreme volatility.
FundingPips also specifically warns traders that account-equity breaches caused by market movement remain breaches regardless of what caused the price move.
That makes the October 4 dispute more precise than a simple complaint that “slippage happened.”
The real question is how much slippage occurred and whether the recorded execution was consistent with the market available to FundingPips at that moment.
A Stop Loss Defines an Exit Trigger, Not a Guaranteed Loss
This distinction becomes especially important on prop accounts with tight daily drawdown limits.
A trader may calculate position size so that reaching a stop level should produce a $250 loss on a $50,000 account, equivalent to 0.5% of starting capital.
But when a stop-market order is triggered, the system generally sends an instruction to close at the next available executable price. If liquidity disappears and prices gap, the realized loss can exceed the original calculation.
In ordinary trading that creates a larger-than-planned loss.
In prop trading it can create an additional consequence: the execution itself can cross an account rule and terminate the entire account.
That distinction makes execution quality unusually important. A few additional ticks do not merely reduce P&L; they can determine whether the trader is allowed to continue operating the account.
Dave Finances recently examined a similar accountability problem after a Propr trader alleged platform lag, missing orders and an incorrect trade direction. In both situations, screenshots and customer recollections can identify a dispute, but server-side execution records are needed to establish what actually happened.
The Comparison With Another Prop Firm Is Interesting but Not Proof
The reviewer says the same trade at another firm produced a far smaller loss.
If both positions involved the same instrument, direction, stop level, lot size and timestamp, that comparison could provide useful evidence about execution quality.
But two prop firms do not necessarily use the same price feed, liquidity source, spread, server location or execution simulation.
Even apparently identical trades can therefore close at different prices during a fast news release.
The comparison becomes much stronger only if the trader provides the exact trade reports from both companies.
The relevant evidence would include the instrument, stop price, trigger time to the millisecond if available, final fill price, bid and ask at the moment of execution and the price path immediately after the news release.
Without those records, the difference between $540 and $1,800 remains an allegation rather than proof that FundingPips produced an unreasonable fill.
The Review’s Own Numbers Need Reconciliation
The arithmetic discrepancy is not a minor detail.
The trader describes the FundingPips account as $50,000, says the position was intended to risk 0.5% and reports a final loss of $1,800, described as 1.8%.
On a $50,000 account, those numbers would instead imply approximately $250 of intended risk and a realized loss equal to 3.6% of starting account size.
That would mean the final dollar loss was more than seven times the nominal 0.5% risk calculation.
If the account really had a 1% daily-loss threshold, the difference is even more consequential: $1,800 would be 3.6 times a $500 daily allowance.
However, FundingPips currently operates multiple account models with different drawdown structures, and Dave Finances has not independently established which specific experimental product the reviewer was using.
The account statement is therefore essential before drawing conclusions from the percentages.
FundingPips Treats Loss-Limit Breaches as Immediate Events
FundingPips’ current rules generally treat hard drawdown limits as point-in-time thresholds.
On models where a daily-loss limit is classified as a hard breach, touching the relevant equity floor can close the account immediately. Recovery afterward does not undo the violation.
This creates an awkward question when the event that crosses the line is itself disputed execution.
A trader may have placed a stop specifically to remain comfortably inside the risk limit, only for the eventual execution price to take the account through it.
The firm’s position can still be logically consistent: market slippage is part of trading risk, so the resulting equity is the trader’s responsibility.
The competing argument is that because FundingPips operates a simulated trading environment, traders need enough execution transparency to establish that an unusually large fill genuinely reproduced available market conditions rather than an idiosyncrasy of the simulation.
That evidence problem has appeared elsewhere in prop trading. Dave Finances recently reported on FundingPips account terminations involving device-ID matches, where the central dispute similarly became less about whether the company had a rule and more about whether customers could understand the evidence used to enforce it.
This Does Not Yet Establish a FundingPips Execution Problem
The October 4 complaint should not be treated as evidence that FundingPips systematically applies excessive slippage.
FundingPips has tens of thousands of public reviews, many of them positive, and a single trader’s execution cannot establish platform-wide behavior.
There are older community complaints alleging unusually large slippage or disputed breaches, but those reports are also unverified and involve different instruments, dates and market conditions.
The broader prop-firm industry regularly produces disputes when profitable accounts meet automated risk controls. Dave Finances has covered cases where Trade the Pool revisited trading activity during a later $50,000 payout review and where FunderBlu traders challenged account closures linked to alleged copy trading.
The recurring issue is not that every enforcement decision is wrong. It is that a trader can lose the economic value of weeks or months of profitable simulated performance based on a single automated event, making the underlying evidence unusually important.
The Tick Data Would Resolve Most of the Dispute
The October 4 case is unusually testable if the trader provides the missing details.
The first requirement is the instrument and news event. Different assets can experience radically different liquidity during the same macroeconomic release.
The second is the intended stop price and exact executed price.
The third is the FundingPips bid-and-ask history surrounding the stop trigger. A sell position, for example, can be stopped by the ask price even when the bid-only chart appears not to reach the same level.
Finally, the equivalent execution from the second prop firm needs to be normalized for account size and position size. The percentages quoted in the review currently do not reconcile with the stated $50,000 FundingPips balance.
If those records show that the market genuinely jumped across the stop with no executable liquidity in between, FundingPips’ slippage explanation would become considerably stronger.
If other market feeds and FundingPips’ own tick history show executable prices much closer to the stop while the account was filled dramatically further away, the complaint would raise a much more serious execution question.
Until then, one thing is already clear: in a prop account with a hard daily-loss threshold, a stop loss does not necessarily cap the amount of account risk.
And when slippage itself can trigger account termination, the quality and transparency of the fill matter almost as much as the stop the trader originally set.
