If you're on the hunt for a reliable semaphore signal indicator that’s all about price action, then the Alpha Trend Spotter is worth a look. This tool is designed to pinpoint the strongest intraday trends and can give you a heads-up when there's a trend shift. It does this by generating alerts, sending emails, or pushing notifications straight to your mobile device.
