Why Use Bands or Channels?

Markets In Relation to Moving Averages

How Far is “Far Away”?

20 SMA w/ 2.25 ATR Keltner Channels

Why Bands or Channels?

Markets behave differently in equilibrium compared to when momentum is driving them.

Looking at how close or how far a market is to a moving average is one way to measure momentum.

Bands are a structured way to measure distance from a moving average.

Types of Bands

Moving Average Channels

  • Offset from a central moving average by a percent of price

Bollinger Bands

  • Offset by a standard deviation (of price)

Keltner Channels

  • Offset by a multiple of Average True Range (ATR)

Keltner Channels

(20 per SMA, +/- 2 ATRs)

Bollinger Bands

(20 per SMA, +/- 2 Std Devs)

Overbought / Oversold

This is an important concept in technical analysis…

But it’s also a thorny concept!

An overbought market:

  • Is potentially over-extended to the upside (“too strong”)
  • And maybe due for a selloff

Oversold is the reverse.

Be Careful

Do not assume that something will or must happen.

At best, any tool only gives us a tilt in probabilities.

This is the definition of a trading edge.

  • Overbought/oversold markets can carry high risk:
  • These points come in strong trends

They can also come with extreme volatility

Overbought markets can get more overbought and stay overbought longer than anyone might expect!

At What Point Was the DJIA Overbought?

Momentum

Several definitions:

  • The difference between two closes (standard TA indicator)
  • Acceleration of the change of prices (slope of an MA)
  • The tendency for strong assets (relative to other assets) to become stronger

The tendency of prices to continue to move in one direction

Offsetting force is mean reversion
