Will an OTC stock sell immediately if I sell on market?

It is obvious that @JoeyV 's understanding of the OTCB and pennies in general is quite limited. There are many MARKET MAKERS on the OTCB

See JOEY under Market Activity....the tab titled MARKET MAKERS...click on the tab and educate yourself.

To answer the question....yes, you will be able to place a market order if you wish but I would not do it if I were you. You run the risk of getting less than you hope for as in the OTCB orders are not handled the same as on say the NYSE and market makers may manipulate the sale of your stock since you have not stated the price you want.

As always, whether your sell order is filled depends on the activity of the stock. If there is millions of shares traded/day and you have priced the stock right it should sell quite fast. If you price the stock wrong you can wait a long time...if there is little activity in the stock you can wait a long time as well.

It really depends on how hot that penny is. Selling at market may get you traded faster but you might be disappointed at the result.

I'll bet your broker won't even let you put in a market order. There is no market. There is no market maker. Why would you think you could sell it immediately when it is not clear that there are any buyers? Duh

challenging factor. search over google or bing. this can help!
