Top reversals are characterized by candles with wide ranges (900 points in this case or a 12,85% taking 7000 as the reference point) and heavy volume (5k vs 1k average), signaling possible trend reversal. Furthermore, the high and low exceed the previous candles creating an "outside candle".
The RSI is also indicating an overbought situation, candles in the upper Bollinger Band, and a possible bearish crossover in the MACD.
