If you want to pay the least commish, try Fidelity or Schwab. Fidelity will not let you trade all pinkies, but it looks like Schwab will let you trade any and every bankrupt piece of junk just like E-Trade lets you do.
SNDD is far from junk, so you can trade it with either of those big brokers. Correct me if I am wrong, but the other two big ones, E-trade and TD will charge you full commission (3, 4, or 5 bucks?) on OTC companies. Schwab is supposed to be buying TDA, so maybe you will get the zero commission deal when they do. Note, even with the zero commission guys, when you sell, you do pay a penny or two for the privilege of collecting your profits.
Yes, profits, with SNDD. Should never be selling this one for a loss. If you have been a bagholder since 0.016, hang in there; soon we should test last week's intraday highs of 0.0125, then the resistance at 0.014, and then finally your bag will turn green, too.
My new goal in life is to be interviewed by Chantel Elloway. When that happens, my comments will be story, observation, opinion, maybe even enthusiasm. What I say will never be instructions on how you should risk your money. Same goes for these posts.
