GOLD buy, last candlestick was a long tail, reversal setup

Last candle on XAUUSD printed a long tail, but closed in the upper third of the candle, meaning price could be exhausted from it's downtrend. There is alot of "room to the left" . Price has not traded here in the past 85 weeks, so there is no proper support. Expected reversals to the upside. I leave SL at 50 pips and TP at one of the consolidation zones
