8) Long the CAC with a stop-loss order below 4390 then short

As mentioned before, there is a massive convergence at 4666 (scenario 2). 4600 could be shorted too, but be ready to suffer some losses if the CAC 40 goes to 4666 thereafter.

My bet would be that the CAC could run down either today or tomorrow to as low as about 4400. Long @4423 seems to provide a good risk-reward ratio.

The afternoon session could become a good scalper's day.

I would be very surprised if the CAC 40 goes much lower than 4400
