Unfortunately, it happens in every book. A bug creeps in and evades the best efforts of the proof readers. These are usually corrected in the second edition. We apologise for the inconvenience. Below are the known 'typos'. They either have been, or will be corrected in the next editions.

**Share Trading**

P 41 Correct address for Australian Technical Analysts Association is:

P 144, fourth line from the bottom of the page:

It uses a scale of 5 with a 1 box reversal.

**Bear Trading**

On page 61 (Original edition) there confusion is between the average price calculation based on share price alone - $4.00 - and the average value based on total purchase cost. In fact we buy 1,000 shares at $7.00 for $7,000, and then buy another $7,000 worth when they are selling at $1.00. We spend $14,000 to collect 8,000 shares at an average value of $1.75. (This error has been corrected in the 2nd edition)

**Snapshot Trading**

There was a format shift between the final proof read and when Snapshot Trading was delivered to the printers, so some of the formulas have been squashed together. This causes problems when they are entered into Metastock. The correct structure is Column Identifier, Column Name and then the Formula details. The correct typical divisions are shown below and should be followed when you transfer the formulas to Metastock.
