From a TA/chart perspective, this 2nd big up day is important. Without those 2 big beautiful white candlesticks from the last two days, the chart forecast would be much more dire.
The market will come back down, back + fill, but at least the case can now be made that a bottoming process is underway, which wasn't the case before.
The chart no longer looks like a falling knife, and suggests a wide sideways consolidation is possible in the weeks ahead. Falling dramatically through the previous lows is still possible, but seems a lot less likely now.
Anyway, that's my 'non-professional' analysis fwiw..
