Painting the tape, marking the close.... All the same idea... MARKET MANIPULATION.
And I actually didn't get in trouble, but got a warning from my broker.
Here's what COULD happen:
Accounts directly or indirectly engaged in manipulative trading practices may be subject to trading restrictions, account closures, and/or regulatory penalties. We urge you to be careful not to engage in the sort of trading activity described above in order to avoid these penalties in the future
