Forex trading comes with a slew of trend trading tools, including trend lines. These lines are a simple approach to determining bullish or bearish forex market runs. Traders can apply these lines to forex charts and use them to figure out how trends can help further their trade. Smoothing out the oscillations within the price action, these lines allow you to plot the rough course of any movement. You can identify a potential bull or bear run. Higher highs indicate a sign of an uptrend, while higher lows demonstrate a downtrend.
