About the competition, I'd trade maximum leverage or close to that (if it's above say 200) with no S/L (or wider than account balance can afford if you must enter one) on a direction that seems very likely to you at the moment (for example long on E/U or short U/Y) use a wide trailing stop of at least 50 pips when you're in profit and add to your position from what you've earned.
Good luck
