After looking into dogecoin pumps in detail, I discovered that there was a strong correlation between impressive doge rallies and the general theme of the altcoin market.
I decided to turn what I learned into an indicator, shown above. The green/red area represents the strength of dogecoin's trend and its direction, and the white/blue histogram is the derivative of the green line.
This pattern is obvious on XLM , but you can see it on nearly every alt. Happy trending
