ZigZag Larsen arrow indicator out & alerts - is a modification of the popular Larsen's Zigzag indicator, which eliminated the redrawing of signals and their lag.
At price reversal points, the ZigZag Larsen out & alerts indicator draws arrows of appropriate color and direction.
Additionally, the indicator has built-in sound and text alerts, as well as sending a message to e-mail.
Note that on the zero bar the indicator signal may still disappear, but on the first bar it will appear unambiguously without re-rendering.
To eliminate the price noise that causes a large number of signals, it will be very effective to use ZigZag Larsen out & alert arrow indicators on the Renko graphs.
