Past news indicator for backtesting

Hello,
I know there's a lot of very good news indicators. But I'm wondering if there's something I can use as reference for backtesting.
I'm testing a strategy based on ranges, and the spikes kill me. So I'm wondering if someone knows about an indicator that shows past high impact news, or if there's an indicator for news in which I can configure the days back so I can at least test two or three months.
Thanks in advance.

Have you seen this?
