The first sign is the lower top ,then 2 strong bearish candlesticks (the strongest since the uptrend began) followed by a lower high to form a busted symmetrical triangle (blown every logical stop order ) to close above the trend line again,MACD is screaming negative divergence ,all are signs of weakness ,but we still need a clear close under the uptrend to open positions ,a close under 1275 would be the safest to open a short position ,target and stop loss will be clear after the break.
