PINE LIBRARY
Atualizado lib_fvg
Library "lib_fvg"
further expansion of my object oriented library toolkit. This lib detects Fair Value Gaps and returns them as objects.
Drawing them is a separate step so the lib can be used with securities. It also allows for usage of current/close price to detect fill/invalidation of a gap and to adjust the fill level dynamically. FVGs can be detected while forming and extended indefinitely while they're unfilled.
method draw(this)
Namespace types: FVG
Parameters:
this (FVG)
method draw(fvgs)
Namespace types: FVG[]
Parameters:
fvgs (FVG[])
is_fvg(mode, precondition, filter_insignificant, filter_insignificant_atr_factor, live)
Parameters:
mode (int): switch for detection 1 for bullish FVGs, -1 for bearish FVGs
precondition (bool): allows for other confluences to block/enable detection
filter_insignificant (bool): allows to ignore small gaps
filter_insignificant_atr_factor (float): allows to adjust how small (compared to a 50 period ATR)
live (bool): allows to detect FVGs while the third bar is forming -> will cause repainting
Returns: a tuple of (bar_index of gap bar, gap top, gap bottom)
create_fvg(mode, idx, top, btm, filled_at_pc, config)
Parameters:
mode (int): switch for detection 1 for bullish FVGs, -1 for bearish FVGs
