Overall momentum is clearly judging by the higher timeframes.
For Longs :
For a buy to be validated we should anticipate a 1H continuation pattern past the last lower high at 3508.5 precisely .
For a short term sell (higher risk) we should wait for a continuation patter around the 3480 mark. If we get this we can take sell to 3439.8 precisely. Again the sell is of higher risk.
