Why short?
First, the uptrend on the higher timeframe (4h-1d) has showing a weakness by breaking a previous higher low.
Second, the price now has reached the strong supply zone from a CHoCH (Change of Character) structure.
Third, There is an imbalance of a candlestick at price 1785.07-1786.10 on 4H timeframe that must to be filled.
Fourth, RSI on the high point.
Fifth, Got a bearish RSI divergence from a previous higher low.
These five reasons is enough for me to execute.
Thank me later and always #DYOR (Do Your Own Research) :)
