There is absolutely nothing wrong w signing a contract as long as you've reviewed it and fully understand the terms. I would be really scared if a firm allows me to trade w/o any contracts. Remember we are in a highly regulated industry and if they don't make u sign one, it would be a reflection on how they run their business overall. I guess other posters might mean lock-up covenants wherein you can't go from their firm to another inside of x months.ETG used to do that years ago .
