Expert Advisors (EAs)
Using an EA / trading bot on Simulated Funded Accounts is not allowed.
You are welcome to use Expert Advisors (EAs) on 1-Step and 2-Step accounts during challenges to enhance and optimize your trading strategies. However, it is crucial for each trader to ensure that their EA settings and trading parameters are tailored to their individual trading style and account.
While it is permissible for traders to use the same EA or indicator as others, each trader must customize their settings to differentiate their trades. The use of hidden EAs or tools designed to conceal the use of an EA is strictly prohibited. Additionally, commercially available EAs with automated trading algorithms are not allowed under any circumstances.
External API usage
External API usage is not allowed on Simulated Funded Accounts.
To maintain fairness and ensure the long-term sustainability of the firm and its traders, all external API usage has been disabled. This includes any third-party tools, applications, or services that connect to trading accounts via API, regardless of whether the access is read-only or execution-based.
As a result, analytics platforms, journaling tools, automation software, trade copiers, and similar services that require API access are not permitted. This policy applies equally to all traders, with no exceptions, to ensure fairness for all traders.
High-Frequency Trading (HFT)
High-Frequency Trading (HFT) is strictly prohibited. Similarly, the use of Martingale strategies or latency-based trading is not permitted. We are committed to maintaining a fair trading environment and upholding the highest standards of integrity.
