Today we look at S&P 500 Index because we have seen a very interesting week waiting for the decision of the FED, scheduled for Wednesday March 22nd. We have already discussed in the latest analysis about the possible scenarios that could appear after the announcement of interest rates, so today our focus is on the medium-long term by looking at the weekly chart. From a technical standpoint, our large time frame analysis has not changed, and the corrective structure still remains valid. Also on the intraday chart, we have an unfinished bearish pattern with a target around $3,700 and this area represents an important medium-term support. On weekly chart the support is around the previous low and this week we will know if this Pattern will fail or work correctly.
