This is a very common technique used to plan an entry by placing a buy stop above the last candle high. The ATR at the point of entry was about 14pips and I typically use a 1.5 to 2 times ATR. The trade is still opened at this point and time and i'm waiting to move my stop loss higher to protect my profit.
I do not know the extend on this rally but I know momentum was strong and a breakout has taken place yesterday. I'd try definitely to stay in the trade as long as possible with the trend.
