FVG(Fair Value Gap) indicator – convert to Trading Code

• 08/07/2025 at 4:17 PM #249481
  Andre Vorster

  Hello.

  Can someone please help me modify this indicator so that it can be used in AutoTrader to open and close trades?
  The indicator works, but I need it to open buy/sell positions when it displays an indication on the screen.
  Also needed only run between certain times of the day as well as position Qty and TS options.

  Thank you.

   

  // FVG (Fair Value Gap) indicator

  DEFPARAM DrawOnLastBarOnly = true
  DEBUG = 0

  // Start of code, don’t change anything below

  IF IsLastBarUpdate THEN
  $RangeHigh[0] = 0
  $RangeLow[0] = 0
  $RangeIndex[0] = 0
  RangeIdx = 0
  BI = 0
  B = 0
  RI = 0
  TotalBars = BarIndex[0]

  IF DEBUG = 1 THEN
  DRAWTEXT(“Total bars: #TotalBars#”, BarIndex[0], High[0])
  ENDIF

  // List all imbalance
  FOR RI = 1 TO TotalBars – 2 DO
  BI = BarIndex[RI]
  //drawtext(“#BI#”, BI, High[RI])
  IF High[BI – 1] < Low[BI + 1] THEN
  RangeIdx = RangeIdx + 1
  $RangeHigh[RangeIdx] = Low[BI + 1]

  Post your topic in the correct forum:
  _ ProRealTime Platform Support: only platform related issues.
  _ ProOrder: only strategy topics.
  _ ProBuilder: only indicator topics.
  _ ProScreener: only screener topics
  _ General Discussion: any other topics.
  _ Welcome New Members: for new forum members to introduce themselves.

  I moved it from the ProScreener support.

  There you go:

  The script is working – does open/close trades.
  Will it be possible for the script to only open positions when the indicator(grey) is activated. When the indicator draws on the screen and not trade at any other time.
  The earlier attached images shows what I try to say in words when to open positions.

  It uses the same code, so it can only enter when the indicator detects a FVG.ù

  If it doesn’t, please post the name of the instrument traded, timeframe used, date and time of one or more incorrect enrtries.

  @ ROBERTO

  Sorry, but I feel that with all the //  that you’ve placed, this script is only selecting these lines:

  IF High[BI – 1] < Low[BI + 1] THEN              or

  IF High[BI + 1] < Low[BI – 1] THEN

  where, however, B1 is always = 1.      Therefore the lines become:

  IF High[0] < Low[2] THEN       or

  IF High[2] < Low[0] THEN

  Is it right or maybe there should be less //  to filter more variables?
