In 1994 J.T. Jackson published his seminal book, Detecting High Profit Day Trades in the Futures Markets. In this book he introduced his "zone probabilities" methodology, which has gained increasing popularity over the ensuing years. Jackson’s statistical research indicated that by examining the relationship between the opening price of the day and the previous day’s close, there was a predictive relationship to the current day’s range.

Jackson’s original 1994 statistical work was updated in 2002 and the results of this update have been coded for the TradeStation platform by Jan Arps’ Traders’ Toolbox as the Jackson Zones^TM indicator.

The Jackson Zones^TM indicator plots the five Jackson zone boundary lines on any intraday price graph and displays on each line the probability that the price will reach that zone during the trading day and the probability that the price will find support or resistance in that zone during the trading day. The information displayed on the zone boundary is:

{Zone number} {Price} {R ( Probability of reaching this zone)} {S/R (Probability of support/resistance in this zone)}

The Zone Probabilities methodology uses the common Floor Traders’ Pivot Formulas to establish the zone boundaries for the current day.

An option is included to permit plotting the mid-line of each zone. This line often becomes a significant support/resistance line.
