I am counting on first second tp, if 1% will be hit put your stop loss in the entry point and leave it be, after each tp do the same, so tp2 hit put stop loss to tp1 and so on.
This is high risk idea ! if it won't succeed I will publish second one similar to this one.
If you have small account and silver is to expensive for you so this idea is more than 10 % of your bankroll don't invest.
