You are allowed to use Expert Advisor (EA) as long such practices not violate our terms and conditions. 

We strictly prohibit any kind of simulated high frequency trading. We also prohibit simulated tick scalping, simulated arbitrage of any kind, and any bot aimed to take advantage of or otherwise exploit the favorable conditions of a demo server and simulated trading environment. 

It's important to note that the use of EAs must follow all other guidelines in accordance with FCT's Terms of Service. 

This includes, but is not limited to:

• Copy Trading from Third-Party Signals
• Demo Account Management Services
• Arbitrage Trading (Latency or Reverse)
• Grid Trading

Please advise caution when using third-party or publicly available EAs. The parameters of the EA you are using must be unique to your simulated account as our internal systems may flag the account for copy simulated trading, which is a direct violation of our terms and conditions. In such cases, an investigation will be launched, which may result in the breach of the simulated account.

Any violations of our Terms of Use or prohibited simulated trading strategies found may result in the breach of the simulated account, rejection of simulated profits, and being banned from our services.
