Finance::GeniusTrader::Indicators::ENV

An envelope is composed of two moving averages. One moving average is shifted upward and the second moving average is shifted downward. Envelopes define the upper and the lower boundaries of a security's normal trading range.

The standard envelope (ENV 25-6) can be called like that : Finance::GeniusTrader::Indicators::ENV->new()

If you need a non standard ENV : Finance::GeniusTrader::Indicators::ENV->new([21, 5])

Finance::GeniusTrader::Indicators::ENV::calculate($calc, $day)
