Self sufficient Trading robot

I am looking for a programmer to create a robot whose function will be to protect my capital, let me explain.

I have been using trading robots for years and it always ended up causing me to lose my capital. I'm currently using a trading robot but I'm still afraid of seeing my account go up in smoke, especially since I'm gone for the week for work and I can't take the only family computer I have because the members of my family need it. I would therefore like to create a robot which will work in addition to the robot that I already have but which will aim to stop the positions taken by the first robot when, for example, my capital is in negative. I would have to be able to configure the robot by choosing the negative balance that I want, that is to say that I can, depending on my capital, choose to stop the first robot when my balance is less than 200th or 300th or other, this way I can have peace of mind knowing that my first robot will not be able to make me lose all my capital but that I will be able to lose at most the amount that I would have configured thanks to the robot that you will have created. I don't know if this is clear to you. THANKS
