So the script... some details!
What I've created is a MACD Wilders based study. By using this study, in TradingView you can take guesswork out of the "curls" and "I think it's curling up? Let me check the blue line and subtract...". Screw all that. It alerts you with big red arrows and big green arrows, and a banner and a message. And it makes sounds. Alert for bullish and a different sound for bearish.
It also has a confirmation component.
If you don't think it's worth it I'll gladly refund your $. I also help you set it up and answer any questions you have.
