(also watch oil this week, give it 3 days as well, don't risk 100% your account and jump to conclusions before this time passes. Also consider the news on the 27th).
Now, I wouldn't reccomend risking more than 2-5% per trade in general. If you're very experienced, perhaps you could get away with that, but even then, it's riskier than going with 1-2% risk max per trade. This forces you to have a bigger capital to achieve a decent profit per month.
