I have been using the power gauge for a few years now and get value out of relative strength graphs and money flow indicators. I do generally check it before making a stock purchase, but I feel it's more like driving while looking in the rear view mirror. It seems to go negative after the price drop and positive after the price increase. I have found other tools that are better as early warnings. Most of the recommendations and dire / urgent warnings either duplicate other services I subscribe to, or don't pan out. Reminds me of chicken little, if you're old enough to know that story. I have never had a need to contact customer service (a plus). Coverage is pretty broad. Some micro cap stocks sometimes don't show - but that's to be expected.
