hello, I'm trying to get some practice on the demo account. I entered Bershire hathaway tonight at 8.30pm 5th October entry point 27945 stop 27090 target 29364 at 10pm roughly it kicked me out saying it reached my stop of 27090.53 but it didn't reach that figure , in fact no where near. I even checked the minute chart. what am I doing wrong ? I need to trust this platform before I invest real money . can someone enlighten me ? Claudy {novice Trader}
