Taking a look at shorter-timeframe chart (hourly chart: 1 bar = 1 hour) we may see mixed sentiment, yet, with bullish dominance (see S&P 500 chart below). When I mention hourly charts I assume 3-day and smaller trends. Majority of technical indicators on this chart have bar period setting less than 20 and multiplying it by 1 hour (bar time frame) you will have maximum 20 hour coverage which is about 3 trading sessions (one trading session is six and half hours long). However, the market is still volatile (see ATR, VIX and other volatility indicators) and I would not bet on this chart for longer than a day ahead. Furthermore, this chart should be monitored during the trading hours.
Overall, as I have already mentioned above, my technical analysis applied to hourly charts show dominance of bullish sentiment (see direction of arrows for each technical indicator). There are still two negative signs: declining SBV and declining Advance/Decline oscillator, however, SBV is almost flat and previous Adv/Decl red area is much bigger than the recent green one.
