As you can see on the chart the 'A' up trade signal has been given but has drifted the last few hours. The only way to prudently get long at this point would be to buy on a close above the key resistance of the 3 Day Rolling Pivot Range (RPR) as shown on the chart.
Once the price pushes higher bring the stop loss up to the Daily Pivot Range low.
This is a good way to see a potential trade despite the market not taking off at the time the trade signal was shown ('A' with the up arrow). This trade still has merit but must reveal a confirmation to the upside before taking a new position.
