Adjusted trendline on H4 as a bullish harami pattern formed which respected the new trendline. Sellers were pushing the market lower until price started to climb again after the formation of the bullish harami and the trendline being respected indicating that sellers are loosing power. Temporary move to the downside doesn't necessarily mean a change in direction of the momentum but we have to look if the market is either retracing or pulling back; in our case it was a pullback since the downside movement wasn't that hectic or require Fibonacci retracement.
Using a lower timeframe can make you fall victim to retracements and pullbacks thinking that the trend bias has changed whereas if you focus on higher timeframes from H4-Weekly you'll be able to see the bigger picture instead of a temporary move.
