The first DEX version (1.0) will be without charting. This version is already being tested on devnet. Sasha has already posted a preview about the UI on his twitter account. Version 2.0 will have charting, I have chatted with the front-end dev on Waves' Slack a few days ago and he confirmed that.
Good news. This should blow up the price What is ETA for in-wallet exchange?
The price has already reacted. With such a pace, I do not think that in-wallet exchange will be available before summer 2017.
I think it would be pretty stupid for the devs to raise expectations of investors and let them down (again), I'm sure this time they will stick what they have said.
If not, well investor confidence is going to be very low.
