Envelopes Indicator Usage

Envelopes indicator consists of two Simple Moving Averages. SMAs together figure a flexible feed in which the price evolves. The averages are plotted around a Moving Average in a stable percentage distance which may be familiar according to the current market volatility. Each line provides as a margin of the price oscillation range.

This indicator gives to trader the following trading signals:

  • Buy when the market price goes the upper line
  • Sell when the market price goes the lower line

Envelopes Indicator Calculation

The upper line is the SMA of the closing price, and is shifted upwards.

Upper Band = SMA(CLOSE, N)*[1+K/1000]

The lower line is the SMA of the closing price, and shifted downwards.

Lower Band = SMA(CLOSE, N)*[1-K/1000]


SMA — Simple Moving Average;
N — averaging period;
K/1000 — the value of shifting from the average (measured in basis points).
