Mql5官网 RAVI Multicurrency 外汇EA

Description

A universal colored multicurrency/multi-symbol indicator RAVI. Was proposed by T. Chand as a trend indicator. RAVI means Range Action
Verification Index.

The indicator may be used with any broker, irrespective of the name of the financial instrument since it is necessary to manually enter the
name as an input parameter. If you enter a non-existent or incorrect name of a financial instrument, you will receive an error message that
this financial instrument is unknown (does not exist).

The indicator is constructed with the period of moving averages 7 to 65 (7/65) and has reference lines recommended by T.Chand: +/- 0.3 and
+/-1.0. When the market is bullish, intersection of these lines with the indicator line is colored blue, for the bearish market – red. This
determines the direction of the trend.

2. MA_Method – the averaging method for the MA.
