A simulator of trading in a tester with a breakeven trailing

I know, I know that you miss your favorite job, your hands are itching to do something good and eternal)) Here's a program for warming up your fingers - a simulator of trading in a tester with trailing for breakeven. Today I improved my trailing a bit, and since I couldn’t test it on Sunday, I slammed two buttons for buy and sell there.
It turned out to be a funny thing, maybe someone will do it for manual testing. It’s a pity that you can’t change the TF in the tester, you could make a normal simulator.
