I trade 9:30 to at least 3:50 (most days till 4:00 and even after), but I am not too keen on logging into someone else's account and I have multitude of other responsibilities so don't think I am interested either. However, curious like others said to see how it goes.
I will say regarding the stealing of funds you mentioned - My brokerage will only send funds to the bank account that sent funds into it and in addition the title name of the account must match the bank account the funds are being transferred to. So if your broker has that, which I think a lot of them do for security reasons, no one can really directly steal your funds. They could just put on erroneous trades though to be a jerk and screw you. With that said I would certainly check someones post history to rule out trolls and also obviously like you said have a voice conversation. Anyone who is half way serious about something is willing to hop on voice, if they have even a second of hesitation regarding getting on voice, than obviously avoid them 100%.
Hope you find someone, but I've found it difficult myself to find people that are actually available 9:30 to 4:00 and are serious about trading.
