lib_fvg

Mis à jour
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
    idx (int): the bar_index of the FVG gap bar
    top (float): the top level of the FVG
    btm (float): the bottom level of the FVG
    filled_at_pc (float): the ratio (0-1) that the fill source needs to retrace into the gap to consider it filled/invalidated/ready for removal
    config (FVGConfig): the plot configuration/styles for the FVG
  Returns: a new FVG object if there was a new FVG, else na

detect_fvg(mode, filled_at_pc, precondition, filter_insignificant, filter_insignificant_atr_factor, live, config)

    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
    config (FVGConfig)
  Returns: a new FVG object if there was a new FVG, else na

method update(this, fill_src)

Notes de version
v6 improved calculation
Notes de version
v7 bugfix
Notes de version
v8 added a fix for insignificant FVG detection before xth candle, did not work due to ta.atr(x) preventing detection earlier.
