This semaphore indicator is based in the standard RSI, which is applied over the Envelopes indicator that shows an envelope or envelope fluctuation borders. This is a version of RSI vs Envelopes drawn in the symbol window.

A sell signal emerges when the upper envelope/border is broken by the RSI indicator from top to bottom.

A buy signal emerges when the lower envelope/border is broken by the RSI indicator from bottom upwards.

The indicator can draw arrows on the indicator, draw vertical lines to keep track of where the entry is located on the chart, play a sound alert upon an entry signal, and send push notifications to your mobile.

If you only need signals upon crossing of the RSI indicator and the standard signal levels, use the RSI alerts indicator.
