The absolute best? Simple…

Always remember that you are using real money to invest in an essentially unregulated market.

Yes, we see ‘regulated by’ in all the fine print – this does mean may be regulated on a retroactive basis – something goes very wrong? Apologies will be made previous oversights, won’t happen again, we assure you, and the the long litigation will begin. You might see a 15cent in the dollar check after 6 years waiting.

And you are using real money, easy to start seeing pips as something in themselves, which they’re not.
