Two Ways to Draw Channel Lines in MT4
What are Support Line, Resistance Line, and Channel Line?
A support line is basically located below the candlesticks and represents the lower bound of price.
A resistance line is, conversely, located above the candlesticks and represents the upper bound of price.
A channel line is basically two lines drawn parallel to each other, with candlesticks moving up and down between them.
Applying to Trading
In trading, you either aim for a reversal from the upper or lower bounds, or you break the lower or upper bounds to
target an acceleration of upward or downward movement (the start of a trend).
In MT4, you can draw various lines such as supports and resistances, or a channel line where two lines are parallel.
There are many ways to draw lines.
I have summarized how to draw lines on my blog, so please refer to it for trading guidance.
