Many traders use different analysis toolkit to make trading decisions. one of which is candle stick confirmations on a major trading zone which could be a support or resistance zone. Most time we trade this candle stick without a double check if it's occurring at a major zone sometimes it could be a setup and if not carefully analyzed could keep a trader stucked.
Also having this candle in a major zone is still not enough confirmation as fake breakout occurs in the market as well. For me i prefer trading the third candle when ever a candle forms any where around a trading zone, be it a breakout or a reversal.
