I normally backtest everything by writing my own code so I can't recommend software to do so. I saw people at other forums using Pro Real Time and similar platforms. They have an easy way to setup workflows with the graphical UI.
There is a really good option with TradingView but requires writing Pine scripts, so you won't escape coding.
If it is not too much work I might have something already for it. Trailing stops are a fairly common setup.
Metatrader 5 is a good option as well, there are tons of scripts on their site that can help you.
