Hallo !
What about these options from the AmiBroker User's guide ?:
LOWESTSINCE
- lowest value since condition met Lowest/Highest
(AFL 1.4)
SYNTAX lowestsince( EXPRESSION, ARRAY, Nth = 1 )
RETURNS ARRAY
FUNCTION Returns the lowest ARRAY value since EXPRESSION was true on
the Nth most recent occurrence.
EXAMPLE lowestsince( Cross( macd(), 0 ), Close, 1 ) returns the
lowest close price since macd() has crossed above zero.
OR maybe:
LLV
- lowest low value Lowest/Highest
SYNTAX llv( ARRAY, periods )
RETURNS ARRAY
FUNCTION Calculates the lowest value in the ARRAY over the preceding
periods (periods includes the current day).
EXAMPLE The formula "llv( close, 14 )" returns the lowest closing
price over the preceding 14 periods.
SEE ALSO The hhv() function (see Highest High Value ).
Kind regards,
Louw
