Hello Edina,
So, the only way to see the margin level percentage is by opening a position. You can open a small one manually to see how it is working and then close it.
But what the Bitcoin robots have as protection is a daily drawdown, which means that when the amount reaches to a specific amount that you have set as a loss, it will stop trading. So, with this option, it is not possible to get stopped out by margin if you set it to an amount that is not for example the whole amount of the account.
There is also an equity drawdown which means that if an open trade, reaches to an equity of the amount that you have set, it will close the position.
About the video, I have already provided you one on how to manage the EAs and there should be some settings as well. If you have not watched, I suggest that you do as it has most of the information you need!
In case you do not have the video, here it is:
Hope this helped!
Kind Regards,
Nikos
