S&P500 about to test zone

We can see the trend channel on the 4H and hours before the NYSE ope we will be sitting at key diagonal support levels. S&P tends to flash crashes in march and it won't be big of a surprise if we see a quick 4-8% test to lower levels. We also have the FOMC this week which could be the catalyst for such a move. The current bullish move looks exhausted already and the trend struggles to get more power towards the north.
