What is RecentHighLowAlert Indicator?

RecentHighLowAlert for MT4 plots the highest high and lowest low from a selected number of bars. The two horizontal references remain visible on the chart and can be monitored for price touches.
N controls the lookback range, while SoundAlert, PopupAlert, and EmailAlert control the available notifications. The indicator offers a simple level display for reviewing recent chart boundaries.
How to Use It in Practice

Read the two lines as the highest and lowest values from the preceding N bars. The band-like spacing can expand or contract, so do not treat the display alone as a reversal explanation.
- Adjust N to compare a shorter or wider lookback before reviewing the new high and low boundaries.
- Compare a touch of either line with the nearby candle history and the rest of the chart rather than using the touch alone.
- Enable SoundAlert, PopupAlert, or EmailAlert only when a touch of the displayed boundary needs to be noticed.
Recent high and low lines are calculated from a clear lookback setting, and three optional notification methods are available without adding extra chart objects.
