The Moving Average Technical Indicator shows the mean instrument price value for a certain period of time. When one calculates the moving average, one averages out the instrument price for this time period. As the price changes, its moving average either increases, or decreases.There are four different types of moving averages: Simple, Exponential, Smoothed and Linear Weighted.

Demarker Technical Indicator is based on the comparison of the period maximum with the previous period maximum. If the current period (bar) maximum is higher, the respective difference between the two will be registered. If the current maximum is lower or equaling the maximum of the previous period, the naught value will be registered. The differences received for N periods are then summarized.

Supertrend is a trending indicator, and like all trending indicators it works well in trending markets . When the Supertrend closes below the Price, a Buy signal is generated, and when the Supertrend closes above the Price, a Sell signal is generated. In Investar this is shown with green and red arrows, so that all you have to do is use the green arrow for Buy and red arrow for Sell.

Bollinger Bands Technical Indicator (BB) is similar to Envelopes. The only difference is that the bands of Envelopes are plotted a fixed distance (%) away from the moving average, while the Bollinger Bands are plotted a certain number of standard deviations away from it. Standard deviation is a measure of volatility, therefore Bollinger Bands adjust themselves to the market conditions. When the markets become more volatile, the bands widen and they contract during less volatile periods.
