I purchased an E8 Funding evaluation account on 10 October 2025 (£738.54) expecting a functional simulated trading platform to assess performance fairly.
Instead, the TradeLocker platform’s automatic 1 % risk tool produced untradeable positions, inflating lot sizes to as high as 128 lots on a £192 k account and triggering “not enough margin” errors.
This means trades could not be placed even when using standard, low-risk settings.
I provided full screenshots, videos, and email evidence to E8 Technical Support (Luke), who confirmed the inflated figures but denied any fault, claiming it was “user misunderstanding.” Their own calculations showed a $341 k margin requirement on a $192 k account, yet they still refused a refund.
When questioned further, support became dismissive and stopped responding, insisting the system was “working as intended.”
This makes the service unfit for purpose under the Consumer Rights Act 2015 and, in my view, structurally unfair to traders who are paying for a legitimate evaluation.
⚠️ Prospective traders should be extremely cautious.
If you rely on TradeLocker’s percentage-risk feature, you may find yourself facing untradeable orders, misleading risk exposure, and no recourse when you raise it.
I have filed a formal dispute and refund claim via my card issuer and provided full evidence of the malfunction.
Technical and Legal Commentary on Systemic Miscalculation
During live testing on a GBP/USD trade in the London session — a highly liquid pair with no scheduled news or volatility events — the TradeLocker platform produced an incorrect lot-size-to-margin conversion while set at a fixed 1% risk.
Despite multiple refreshes of the interface, the underlying error persisted.
On execution, the trade risk exceeded the selected 1% by 0.2%, and once the stop-loss was triggered, a further 0.6% risk was deducted.
In total, the system extracted 0.8% additional risk exposure from the account without user input or consent.
This behaviour is mechanically inconsistent with the principle of fixed-percentage risk management, which by design should cap total loss at the percentage selected by the trader.
The fact that the over-exposure occurred on a major pair under normal market conditions demonstrates a systemic defect in TradeLocker’s risk-engine logic, not a situational anomaly.
Such functionality failures constitute a breach of:
• Section 34 (Digital content to be of satisfactory quality), as the software’s calculations were unreliable and materially impaired usability;
• Section 35 (Fit for purpose), as the product failed to simulate realistic trading conditions; and
• Section 36 (As described), as the service did not perform according to its advertised risk-control features.
E8 Markets’ continued use of this defective platform without acknowledgement or rectification represents a deliberate tolerance of a known fault, unfairly skewing evaluation outcomes in favour of the provider.
This conduct places traders at a systematic disadvantage, compromising both fairness and transparency under the Consumer Rights Act 2015.
Note on Platform Control and Configuration
TradeLocker operates as a white-label trading interface whose execution parameters are defined by the hosting firm.
In E8’s implementation, the risk-to-margin scaling error occurs even though the same logic works correctly on TradingView’s native simulator, which uses the same charting engine.
This indicates that the fault lies within E8’s own configuration or risk-management overlay, rather than the base TradeLocker software.
If intentional, such configuration would artificially increase trader failure rates and breach the implied term of fair dealing under the Consumer Rights Act 2015.
