End of Day Trade

[aqr]

what's the best way to trade SABcfd using only the last price of the day? say the 16:50 price before the closing price at 17:00? i'm using pivot analysis and I seem to be bleeding cash all round.. can't really say I gave up on the Index using pivot analysis too - to me it appears the 5 min chart if you have the time will work wonders..
