What does "trading range" mean here?

Great question!
Sometimes a stock will bounce around in a certain price range - for example between $8 & $12 over a long period of time. This is referred to as the 'trading range.' The chartist that you were quoting is essentially advocating that you would want to wait to buy a stock until it breaks OUT of the identified trading range. So, in our example, if the stock that has been bouncing between $8 and $12 for 18 months suddenly jumps to a new high of $14 because of more profits and earnings due to a new project, product or service, then this may, according to your quoted authority, be an opportune time to pick up the stock.
Hope you found that most helpful....
Best,
