Many traders ask themselves, when the S&P will make the next down-leg. Renko-chart indicates that it could be at 2870 or if stretched, at 3000. Indicators TSI and WT are also indicating that we have reached breaking levels. From my gut feeling I would guess that traders don't want to go with large positions into the weekend and a sell-off could start at Friday (Asia trading) going well towards middle of next week. What to watch is really: 1. Renko-chart and 2. candle types developping during the afternoon after which a descision for a short position into the weekend could be made or not.
