In the wake of the European markets, while Pékin and Washington would consider returning to certain customs taxes before signing a "phase 1" agreement, the S&P500 index should start the session slightly higher by 0.2%. 
The U.S. index ended with a gain of 0.37% to 3078 points yesterday, driven by the progress of trade negotiations. 

>On a macro-economic level, operators expect the Final PMI services index and the ISM services index at 15:45 and 16:00. The latter are expected to be 51 and 53.5. 

Graphically, no change, the trend remains positive in hourly data above the 3066 points, the lower bound of a gap left open yesterday. Only the lowering of this level would militate for some profit taking towards 3050 points then 3038 points.
