The third suggested Directional Movement filter is: When ADX turns up or turns down.
There are several ways to measure this:
-
ADX today is greater than ADX
yesterday. This may be too volatile, requiring some
form of smoothing (as in the options below).
-
ADX has risen for x days (or fallen
for x days ). If the user inserts a value of "1" day,
the result is the same as for "1." above. If they insert a
value of "2" days, the security will be included only if ADX
has increased on 2 consecutive days.
-
ADX today is x points above (or
below) ADX from 5 days earlier. This way we need only keep 2
fields on the database: ADX today and ADX from 5 days
ago.
-
ADX is the highest (or lowest) in the last 5
days.
- ADX crosses to above (or below) a value x inserted by the user. For example: ADX crosses to above 20.
Please post your preferences at ADX
on the Chart Forum.
(Note that where I mention "5 days" we may offer alternative
options such as 2 or 10 days).
