Decreasing volume, classic topping patterns, predictable fib level resistance appearing.
The whole rally got stopped by the daily 200 moving average; there are some interesting patterns going on on the daily to suggest this is just a little correction in a downtrend.
Short below the lower of the two thin black trendlines for a bounce to the thicker one, back up to thin or nearest fib.
Short more if we fail to bounce there, look for support zones.
Then there will be a ' double bottom ' bounce around 6600 or even on the confluence of bottom trendline, red fan line, 0.5 fib @ 6950
that bounce isn't really sign of bullish reversal until back above the thicker black trendline that we would have lost a few days before.
I've drawn this on an hourly chart but it might take longer, and play out on the 4h or daily instead, i'm just identifying levels here.
