The SHI Channel Forex Indicator is a popular and free MT4 indicator that is useful for traders of all levels. The indicator works by plotting two lines on a chart. The first line is a support line, which is plotted along the lowest points of the chart. The second line is a resistance line, which is plotted along the highest points of the chart. These two lines form a channel that can be used to identify trends in the market. The SHI Channel Indicator is a powerful tool that can be used to help traders make informed decisions and maximize their profits.
