Moving Average Bounce on an Uptrend

BTC/USDT is on a clear uptrend on the 1h, 4h, and daily timeframes. I define my trend based on moving averages (6 EMA>18 EMA>50 EMA> 200 MA). Since price is on an uptrend, the best time to buy is during a pullback/retracement to area of support. Price as respected the 18 EMA previously multiple times so it is a reliable support (white circles). A bullish engulfing hammer was spotted at the 18 EMA average and also coincide with the 0.618 fib retracement (trigger candle). Buy stop order is placed right above the high of that trigger candle.
