I am finding that the use of Standard Pivots on Day/Week/Month combined with 5,10,20 Avg Daily Ranges are often very accurate Hgh/lows of the day, had two winners recently.
Key was no High Impact News near the trades. Actually I traded these prior to high impact news expecting chop and scalped of Pips.
GBP/USD 5/10 SOLD 1.6170, High of day 1.6181 11 Pips minus spread
EUR/USD 5/14 BUY 1.2832, Low of day 1.2825 7 Pips minus spread

Using Fast Track Trader Thermal Price Grids, Day/Week/Month Pivots , and Avg Daily Range...is very simple and powerful approach. I draw Trend lines and Support/Resistance lines and read Price Action.
I watch M5, M15 and H1 charts
