The bulletin board is a non regulated market so there’s no way you can have any advantage over any else trying to "mess" around.

I’ve been in the industry for over 40 years and have never seen or heard of a "pre market boom" and I have managed all types of trading functions in various markets

You’re looking for something that does not exist, if it did most firms would be out there participating and as of the close of business on Friday, none of them are out there.

You buy 1000 shares of $.10 stock that jumps to $.20 and you sell. You make 100% on your money…right? Well not so quick need to do the math. You made .10 x 1000 = $100 plus you have your original amount of $100 for $200. You forgot the broker fees….to set up the broker account might be a small fee of $5 or $10. There is also the transaction fee to purchase of $10-$20 and to sell there is another fee we’ll say $10.

So….you started out with $100 and spent $5 to set up the account and $10 (or more) to do the purchase so you actually only have $85 to invest. You buy 850 shares (at .10) and they double in price and you sell for $170 (.20 x 85). But when you sell you have to pay $10 so you end up with a total of $160 on investment of $100 or only 60% net return. NOW remember you owe taxes on your gain so come tax time deduct a 10% capital gains rate on $60 for another cost of $6. Net profit $54 with a lot of risk.
