The major Support at 4137 was tested on Thu and Fri and pre-RTH today it has been tested again but Value Areas have been generated above that level so I say the Support has held so far.
The other level we are monitoring is 4159 and that Resistance was in play on Friday and again on Monday.
ST: The minor (7week) Control has now migrated to 4151 and may come in to play today as a level of Resistance.
