From that link of yours;

"However, the key is knowing the difference between two types of overbought: Climax Action (which usually occurs near major tops) and Kickoff Action (which usually occurs near the start of a major run). They look the same as the market goes straight up for two or three weeks, but the difference is when the action occurs within a stock’s overall run
Kickoffs, on the other hand, usually occur after long periods of no progress and are a sign of strength"

Sounds more like Ladbrokes  giving advice on a soccer match.
