Signals for trading

Hello everyone! Has anyone here traded with the vfxAlert app? I downloaded this app and to me, it seemed very useful. Signals are very accurate in most cases, they work with many brokers. I’ve appreciated this app and I’ve obtained the Pro account. The Pro-account is also good, but I still don’t understand clearly how to work with the heatmaps. That’s why I would like to know how to use it properly. If anyone works with vfxAlert, please, share your opinion.
