Coral Trend Alert Indicator

New Coral Trend Alert indicator

This is a new redesigned and improved well-known coral trend indicator.

Coral is a powerful trend following indicator that uses 3 indication to define and to clear a trend direction signals.

The green line indicates a buying trend, the red line indicates a selling trend, and the yellow line indicates is a neutral.

We have accelerated the calculation of the indicator, added arrows and two signal modes: when the line color changes, when the price crosses and the candle closes above / below the coral line.

We also added trend filters and the ability to connect this indicator to any of our indicators as a signal filter, as well as the ability to connect the indicator to our Expert Advisors for automatic trading.

We also added the ability to change the parameters of the indicator, which was not in the original version.
