Could several people please give insight into the follwoing at different firms: I'm about to start trading with one of the prop firms that is mentioned on here frequently. For example, like a Worldco, a Bright Trading, a Shill, a Hold. Do these firms require you to be in the office trading for a fixed amount of hours each week. i.e, you have to be there every day of the week trading. Or, maybe you just need to be there enough each week to make your seat worth their efforts. I mean, these jobs do say that you are "an employee trader". So, will it affect your benefits (ie helthcare etc) if you decided to take a week or so off here and there to attend to things in your outside life. The reason I'm asking is because I'm trying to figure out if it is reasonable for me to think that I will be able to take time out of my trading week every so often to put time into a business that I am starting as well. Any and all insight would be appreiated by everyone at different firms. Thanks very much.
