Very clear S/R neckline

The neckline shown a clear cut resistance and support for the highlighted area.
In a downtrend, when price retraces back to the area between 8ema & 20ema, any candlestick bearish signal can produce pretty reliable sell signal.
After two high spin doji, i shorted at 132. Taking 50% profit last night.
Now, price will try to retrace back to 20ema again, any rejection candlestick pattern will allow me to let my remaining 50% run.
