For me moving average crossovers are good only to confirm the direction we are heading.Even with the 6/50 cross it comes late in the game and you need to rely on other things to pick the tops and bottoms.
I use multiple time frames,equity p/c ratios and 10 day Trins to try to pick the direction along with the tops and bottoms.
I think the next stop will be in the 1700-1750 range.Of coarse not straight up.
