The 54.70 level corresponds to a gap fill and a 61.8% Fibonacci retrace. I'd consider taking this trade on a hit of this level with a confirmation stop just below it. If this level breaks, there will be secondary support at the pivot low of 53.16. This trade is somewhat higher risk due to the precipitous fall it has seen recently, but could bounce as it's very oversold.
If the level holds, look to take profits at the 200 moving average and use a trailing/breakeven stop thereafter.

Please be advised that if the market looks to fall early next week, I will not take this trade. Always be aware of overall market conditions when taking any trade and never fight the market.
