EA for DEMO servers

The EA should place the stop loss in the middle of the spread on demo servers with fixed spreads. These EAs only work on DEMO servers due to the fixed spread and fictitious liquidity, and not on real servers as the spread varies and cannot be placed. the SL between the bid and ask. I need it to have the trailing stop function added, as it has to protect the trade at B.E when going from a positive tick, and close at SL when going negative. The instrument to negotiate I think it could be the US30. I am sending you an example video so that you understand exactly what I need, from min 8:44 to 12:30, https://www.youtube.com/watch?v=d3MjxezTDOw&t=458s. If you are interested in this project, please send me your proposal so that we can discuss the details and the budget of the project. Thank you."
