Support and Resistance in Amibroker

I need to identify 4 different highs and lows

first high is when

HIGH POINT =
VALUEWHEN

HIGH < REF (HIGH ,-1) AND REF (HIGH, -1) > REF(HIGH, -2)

REF(HIGH,-1) IS "HIGHPOINT"

we call above condition as "High Point"

Second High

HIGH =

VALUEWHEN

HIGH POINT < REF ( HIGH POINT, -1) AND REF ( HIGH POINT, -1) > REF ( HIGH POINT, -2)

REF(HIGH POINT, -1) IS "HIGH"

Third High

RESISTANCE =
VALUEWHEN

HIGH < REF (HIGH,-1) AND REF (HIGH,-1) > REF (HIGH,-2)

REF(HIGH, -1) IS "RESISTANCE"

Fourth and Final high

TOP =

VALUEWHN

RESISTANCE > REF ( RESISTANCE ,-1) AND REF ( RESISTANCE ,-1) > REF ( RESISTANCE ,-2)

REF(RESISTANCE,-1) IS "TOP"

First Low

LOW POINT =

VALUEWHEN

LOW > REF ( LOW , -1) AND REF ( LOW , -1) < REF ( LOW, -2);

REF(LOW,-1) IS "LOW POINT"

Second Low


LOW =

VALUEWHN

LOW POINT > REF ( LOW POINT, -1) AND REF ( LOW POINT, -1) < REF ( LOW POINT, -2)

REF (LOW POINT,-1) IS "LOW"

Third Low

SUPPORT =

VALUEWHEN

LOW > REF ( LOW ,-1) AND REF (LOW ,-1 ) < REF ( LOW , -2)

REF( LOW,-1) IS "SUPPORT"

Fourth Low

BOTTOM =

VALUEWHEN

SUPPORT > REF ( SUPPORT, -1) AND REF( SUPPORT ,-1) < REF ( SUPPORT ,-2)

REF( SUPPORT, -1) IS "BOTTOM"

THAT IS THE GENERAL IDEA
I COULD ABLE TO PLOT HIGHPOINT, LOWPOINT
AND HIGH LOW VALUES

BUT NOT ABLE TO FETCH RESISTANCE / SUPPORT AND TOP BOTTOM LINES
