There is a clear upward sloping triangle on the chart with a previous false break to the downside. However, with the climactic action of the last days, it seems a breakout pullback entry would be warranted.
There is a small rejection candle with a tail rejecting the price below the last few candles. It is a little bit weak since the price has been in a range but the lower tail did break below. It is also rejecting the trend line and the line parallel to the trend channel line.
Put an alert on the lower extended line and come back to short it if it breaks down. Be careful, a few support lines can be traced with slightly different angles using different low. Price action should give more indication as it approaches it.
