How to use the Gann Pressure Dates:
Best way to use them is to mark the top and bottom of that date and whenever price breaks out of any of these levels and sustains, positional entry can be taken.
Gann used to believe that 21-March is the financial year start date. So, all pressure dates calculated by taking 21-March as start date are called static gann dates. Trend changes are expected around those dates every year.
Similarly, dates calculated by taking a major trend change date from the past as starting point provides the dynamic Gann dates having the same effect.
In case, any date fall on a trading holiday, nearest trading date can be taken into consideration.
