SPI Monthly and Weekly cycles
3rd quarterly 50% level forms resistance, and whilst below that level there is always the chance that the market makes its way down towards the July lows, & then 3784.
However, it would need to be trading below the Weekly 50% level @ 4078 to help verify that move.
Otherwise, keep an eye on the Weekly 50% level, & if it bounces off this level and next week closes above the 3rd Quarterly 50% level..
Then the UP trend will last for 2-months:- August/September. (#B)
