Anyone actually using stock trading signals as part of their investment process?

I spend hours every weekend reading macro commentary from like 5 or 6 different sources and they all contradict each other. By Monday morning I'm more confused than when I started. Starting to think stock trading signals from a systematic approach might cut through that noise better than me trying to synthesize everything myself. Has anyone used a signal service long term and actually found it worthwhile? Mostly interested in S&P 500 or broad equity exposure, not individual stock picks.
