There is a strong Support/Resistance area between 250 and 252, which hasn't been broken. It is at the tip of an ascending wedge with a negative momentum divergence, along with very little orders beyond 2000. Which can be read as few institutional participation since it reached the third wave in the uptrend. If this level is not broken then Today's close is still weak. if the support trend line is broken on Monday then a downtrend will be ignited.
