Part 1 established the following:

A stock’s movement is its volatility.
Average True Range (ATR) is a measure of volatility.
ATR can be used to position-size to account for volatility.

And we examined the chart below and performed some calculations…

Using the ATR(10) indicator in the bottom pane of the chart, we divided the ATR(10) by the [...]

Customary position-sizing has the trader buy X number of shares and set a stop to so that he does not lose more than X dollars. One drawback of this method is that it does not account for the volatility of the security being traded. Volatility is a measurement of change in price over a given [...]
