A common psychological trap the market sets for us is buying right when the price reaches a resistance level, hoping it will break through. Of course, we've been on an uptrend, and it's easy to think it will continue, so we buy.
But then, right after we buy, the price pulls back, leading to losses and giving the impression that someone is watching our position.
Therefore, it's always better to buy after the resistance is surpassed or on the pullback towards it because a broken resistance becomes support.
