People were waiting for market crash last week. Now after a joyous 300pts rally, market is loaded with long contracts, fantastic liquidity for institutions to accumulate short positions.
Tomorrow they will begin to let the market slide. 22300 to 22250 is crucial. Retailers failing to hold the market there will result is stoploss triggers and panic selling.
Candle stick, price action with respect to trendlines, behaviour of the trend, I see several indications for the beginning of a crash.
