The Target Bands Indicator is a popular and free Forex indicator for MT4 that is useful for traders looking to identify and take advantage of breakouts. It works by plotting two bands on the chart, one above and one below the current price. These bands represent the upper and lower targets for the market. When the price moves outside of the bands, traders can take a position in the direction of the breakout. The indicator also includes a signal line that can be used to confirm the breakout. This makes the Target Bands Indicator a powerful tool for traders who want to take advantage of breakouts in the Forex market.
