Home retail traders tend to be private. Thus, not sure what you meant by "get to know other" traders considering you're already here at this forum. Simply, seems like this forum is not what you're talking about because if it was...you wouldn't have started this thread.
I highly recommend you try to meet traders in person nearby your city of residence and then use online personalities as secondary. Meeting others in person in my opinion could result in opening the door to other things that may be useful in your trading.
In person is what I mean. Sure, retail traders are a private bunch. Still, it would be good to have trading 'colleagues', the way all normal working people do. The issue is how to reach out and find them.
