I do not speak Polish, but I can help you with your other questions,
If the stop loss parameter is zero or lower than the current spread, this will submit an order with no stop loss, as shown in your last image and explained by Sebastian and Sophia. It is the cTrader platform that does this and not cBot.
You will never have the same results with a backtest compared to your actual results when you start the tests; even 1 hour can make a big difference, but the biggest problem is your backtest settings, as shown below.
Use tick-data for the closest match.
It would help if you provided your backtest settings as shown above and your cBot parameter settings together with a backtest start and end date; with this, I can run a backtest on my PC.
Please understand that if you are getting different results on a backtest compared to a live test, it is either your backtest settings that are not using tick data or an issue with cTrader; in this case, you will need to contact Spotware.
Why not use a stop loss like 50? Just because the optimizer recommended a spread of 0.8 does not mean you should use it; it is well-known to never use such a tight stop loss with trading.
