Trends
Upward, downward and sideways moves. Highs, lows and timeframes.
An uptrend is a series of higher highs and higher lows. A downtrend is a series of lower highs and lower lows.
A sideways move (range) is when the price swings within a band without clearly making new highs or lows.
A trend is always tied to a timeframe: the daily chart can be rising while the 5-minute chart is in a pullback.
