A 'Supertrend' indicator is one, which can give you precise buy or sell signal in a trending market. As the name suggests, 'Supertrend' is a trend-following indicator just like moving averages and MACD (moving average convergence divergence). It is plotted on prices and their placement indicates the current trend.
The buy and sell signals are generated when the indicator starts plotting either on top of the closing price or below the closing price. A buy signal is generated when the ‘Supertrend’ closes above the price and a sell signal is generated when it closes below the closing price.
It also suggests that the trend is shifting from descending mode to ascending mode. Contrary to this, when a ‘Supertrend’ closes above the price, it generates a sell signal as the colour of the indicator changes into red.
A ‘Supertrend’ indicator can be used on equities, futures or forex, or even crypto markets and also on daily, weekly and hourly charts as well, but generally, it fails in a sideways-moving market.
