This MASTC indicator is a combination of Moving Average & Supertrend with default value of 10 & 10,3.
SuperTrend is one of the most common ATR based trailing stop indicators.
A ( ) is an arithmetic moving average calculated by adding recent prices and then dividing that by the number of time periods in the calculation average
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.
