"What do you show as the 200dma ?
What data feed?"
I am trading CLK3 (May 2013 contract).
I am feeding Sierra Chart ($36/month) from IB data (free with account) for this. (I use Iqfeed ($85/month) for stocks because IB data is no good for time and sales which is key to my identification of turning points for individual stocks and the indexes (time and sales for SPY in conjunction with ES futures as a pair is an amazingly predictive thing to watch due to the arbitrage between the two).
Anyway, for CLK3:
20 day SMA: 92.60
50 day SMA: 95.11 (rolling over and acting as overhead resistance)
200 day SMA: 92.45 (more or less flat)
"They" had reversed CLK3 at or just above the 200 day several times in the last several sessions, without gunning the stop loss orders just below, and that, for me, said it was going to break (may seem counterintuitive, but a lot of tape tells involve reverse psychology (used by the bigz to wrongfoot the Green Peas)).
