Eyes parity level
The USDCHF is breaking below the 100 day MA at the 1.0036 level and trades at new session lows. The pair is approaching the parity level at 1.0000 (natural support. The 38.2% of the move up from the May 4 low is at 1.0006.
Other support targets include the 200 hour MA AND 50% retracement at 0.9977-79. When the 200 bar MA and 50% converge (and the 100 and 200 bar MA are a good distance away from each other - see smoother blue and green lines), there tends to be support buyers/profit takers. Be aware.
The 200 day MA at 0.99589 is also a key support level.
As Adam points out, the EURCHF is also on a move lower.
