Library "LocalLimit"
Calculates the local upper or local lower limit for a given series. Applying multiple passes produces what appears like support or resistance levels.
See Local Limits for more detail.
upper(src) Produces the recent local upper limit for a given series.
Parameters:
src: The source series to derive from.
lower(src) Produces the recent local lower limit for a given series.
Parameters:
src: The source series to derive from.

Release Notes:
v2 Added option for padding.
Updated:
upper(src, padding) Produces the recent local upper limit for a given series.
Parameters:

Updated:
upper(src, padding) Produces the recent local upper limit for a given series.
Parameters:
src: The source series to derive from.
padding: Gives some extra room when lowering the level.
lower(src, padding) Produces the recent local lower limit for a given series.
Parameters:

Release Notes:
v3 Fixed issue with na padding causing nothing to show.
Release Notes:
v4 Handle NA values.
Release Notes:
v5 Restored previous demo code. Added trend function.
Release Notes:
v6 added trend function (missing export).
Added:
trend(src) Determines the local trend of a series that and persists the trend if the value is unchanged.
Parameters:
src: The source series to derive from.
@return +1 when the trend is up; -1 when the trend is down; 0 if the trend is not yet established.
Added:
trend(src) Determines the local trend of a series that and persists the trend if the value is unchanged.
Parameters:
src: The source series to derive from.
@return +1 when the trend is up; -1 when the trend is down; 0 if the trend is not yet established.
Release Notes:

of(level, padding)
Creates a Level object representing the local upper and lower limits.
Parameters:
level: The source levels to expand of.
