I don't think we can post links even for non-fish related sites but I will tell you that other than finacial sites to do due-diligence research, there are no expert sites for anything. Unless you know what you are doing, DO NOT JOIN OR TAKE ADVICE FROM MESSAGE BOARDS! (Except from me on this one.
)Most of these are "pump and dump" postings and penny stocks will break you in no time. You can pick a lucky stock every now and then and some people on these boards seem like experts, but it all boils down to the saying "Even a blind squirrel finds a nut every now and then."
If you want to have an advantange trading stocks, pick quality stocks (not penny) and learn a little about Technical Analysis. It's not that difficult and you will still make bad choices at times. The key is to protect your buys and win more than you lose. It's kind of like playing black jack. You can't win every hand, but if you can count cards and win more than you lose, you make money.
I'm not a day trader, but I buy and sell everyday in the market. I'm what they call a swing trader. I may hold a stock a few hours, a few days or a few weeks but not much longer than that. I don't fight the trend and I make money in bull and bear markets because I buy, sell, short and cover stocks as needed. On any given day, I'll have about 10 orders in on market open with buys, sell, short and covers sometimes totaling 6 figures. I never place market orders (limits only) so they don't always execute. On average, probably 3 a day get executed.
Sorry, I know you did not ask for a stock lesson, but I've been doing this for a long time. When I see someone asking for information about penny stocks, I just want to make sure they understand the risk. I only give you the above information to qualify my experience. I'm a big believer in the stock market and you can make some very good money in it, but it is a risk you have to manage or you will lose every time.
Good luck and go slow.
