I had a limit order sit with my broker for several days, OTC issue, sell. The reported exchange data showed that the price had been above my limit on each of the previous 4 days. I emailed them to see why no transaction and got the following message: ==Dear Trader, This security, SALN, trades on the OTCBB where quotes are not firm. Quotes on the OTCBB are indications only and market makers are not held to those quotes or obligated to transact at the indicated prices. If you have any further questions, please feel free to contact us again. == Wow, how does one trade these issues then? I had no problem getting into the position, trades fired off like crazy but I could not unwind it. I got out at breakeven eventually. I think the main problem was that I was trying to sell more than is sold in the typical day, this thing was too thin to get into in the first place. I can overcome that in the future but still, it looks like the MM's can do as they please to some extent.
