Doubt there is a way to collectively play ET'ers sentiment... too diverse. However, the website Traders-Talk.com has some votes tallied by the moderator. Seems sometimes it's good to go with the majority vote, sometimes better to fade them.
Been using basic concept since late 1991, system goes against 9 year cycle extremes but has become a most complicated hedge/system in last 18 months as I have added physics to various components to curb risk/drawdowns even further. As Nasdaq made new highs, program waits for certain pattern to go short. System will also find areas where rally/dip against it long term positions exist and will hedge open positions as it did recently before mid February. Often times hedges comes from other instruments so as not to disrupt options in futures. I am now testing on stocks as many have similar personalities as commodities. I don't recommend to most others as takes abilities to counter-trend trade and years at least for me to get profitable, and for most people it goes against what "seems" right thing to do catching falling boulder. This method has extremely low winning percentages as it might take years to be considered a profitable trade but so is the losing percentages/drawdowns. As far as scalping/day/swing trading, 95% are against immediate trend. For me breakouts/trade with trend, never made much sense because risk was too high for me to fathom.
