An uptrend describes the price movement of a financial asset when the overall direction is upward.
In an uptrend, each successive peak and trough is higher than the ones found earlier in the trend. The uptrend is therefore composed of higher swing lows and higher swing highs. As long as the price is making these higher swing lows and higher swing highs, the uptrend is considered intact. Once the price starts making lower swing highs or lower swing lows, the uptrend is in question or has reversed into a downtrend.
