Minor Resistance today is 4145.50. Price above that level would be a stronger position.
The minor VAL is at 4087 (dashed on chart) – if Bulls are in control of the minor time-frame this level could Support.
More important Support at 3989.
In the longer-term the reduce risk point remains at 4048.50 (triggered by a RTH close below that level) and this level has not been threatened since the start of the month.
