Consider this example. I have done this three times lately with PNMS.
Buy 2,000,000 shares @ .0012 for $2400.00 (9.99 commission)
Sell 2,000,000 shares @ .0015 for $3000.00 (9.99 commission)
Net Profit $580.02 or 24.17% for a $2400.00 investment and 2 days of trading.
You can raise the numbers or lower them as you see fit. I usually look for high volume whenever possible. If the ask is stacked very deep, I will typically sell at .0001 less than the stacked portion. (easier to take profit before it peaks)
Slow and steady is the way to go
