To explain Ardor, it is a complimentary token to NXT which allows all it's childchain to utilize NXT technology. Therefore we can pair them both up when there's a price movement.
Upcoming next few weeks, there will be an Jelurida ICO which requires NXT to purchase. As the next three rounds of Jelurida ICO sale, the price of NXT to Jelurida ratio decreases, we can assume that NXT prices will continue to rise if one were to purchase an equivalent amount of Jelurida. (NXT News)
NOTE!!!: (I haven't consider if the NXT collected were to be dumped back into the market.)
Also, For 1 JLRDA token the participants in the ICO will receive 1 IGNIS coin at the time of the Ardor Genesis Snapshot. Snapshot will be taking place in Q4 as well. (Positive Ardor Sentiments)
Next for the Ardor roadmap, 2017 Q4 has one of the biggest update, which is the launch of Ardor mainnet launch. Which allow the spawn of child chains and necessary migration. (Positive Ardor Sentiments)
Lastly, to be honest, NXT is undervalued in my opinion. And I chose to do a TA in NXT and not Ardor simply because NXT isn't receiving enough attention.
