These alerts track the stochastics for a stock on a 5, 15, or 60 minute chart.  If the stochastics say that the a stock is overbought, the server reports an alert as soon as the stcok is no longer overbought.  If the stochastics say that the a stock is oversold, the server reports an alert as soon as the stock is no longer over sold.

The formula watches the 80 and 20 lines to determine overbought and oversold.  It reports as soon as the %D for the fast stochastic or the %K for the slow stochastic crosses the line.  We use our own proprietary analytics to filter out noise when the stochastic is hovering near a line, constantly crossing back and forth.

This alert is signaled by an individual print.  We do not wait for the end of the candle to report it.  This means that we report the condition sooner.  It also means that a historical chart might not always match the alerts.
