You may not find this as interesting as I do but here goes.
if you look at the two charts below you will see I have marked the 1/2R levels that have provided clear Support for the emini SP500 and the Spyder.
The interesting thing is that the 1/2R on the ES chart comes from the Range since the August high and the 1/2R on the SPY chart comes from the Range since the Aug low.
The other interesting thing to note is that they have both just broken down. This is minor stuff but is a first indication of weakness if the charts remain below those levels.
