i am not familiar with that EW and what it stands for, but seems a good idea if the purpose of creating a group is for sharing an idea and technical analysis something like that.
Btw i use to analyze and making ideas in the market when day trading but only crypto. So if this is for crypto trading then i am interested to join because it will be more fun IMO.
I think that the already existing telegram groups are enough for everyone to find for themselves what they want. You just need to make the right choice among the existing channels. The creation of a new channel and community will take a lot of time and it is not a fact that it will be successful.
