This was today's SPX Forecast, you might find it of interest:
The daily chart below shows our present situation - I outlined earlier in the week the "Platform of Lows" support and this time we outlined that the platform of lows also features the first candle in the sequence which is the anchor for the present trading range... as it is the "LAST DAY OF EXTREME VOLUME" from the September OPEX... So that range is 2131.20 - 2146.48 and as you can see we're breaking down out of a LONG SIDEWAYS MOVE, we had a lower low this week on Thursday and then a lighter volume bounce on Friday... and that move failed to break the low of the REFERENCE CANDLE from 9/16 (last day of volume). Yet we closed near the low and the SPX closed up fractionally. Closing inside that reference candle however, offers a HINT of strength going into Monday. Overall though we can see that the SPX has it's work cut out for it as it was unable to break and hold the high of the reference candle at 2146... we had two attempts at it including Friday and they were both rejected. We do have another OPEX on Friday, so indeed the next few days will be important. So with that HINT, we move forward into Monday... we know there is little room here for any failure to rally, because the Longer term daily support at 2131.20 is directly underneath this 2132.98 close.
