SP500. Is the Fun Over?

The previous target price set in February is in doubt. The large options spread closed down 50%, with a move to the profitable side along the way. The sentiment is negative.
The large option level (see chart) may act as a support level on the downside.

評論:

It draws attention how a major player can accurately determine resistance levels and exit positions on the way to such a level. Are there any other publicly available market analysis tools that allow for this? This may be a rhetorical question aimed at participants who do not consider studying option analysis necessary and base their market view on lagging technical indicators and unclear fundamentals.
