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

Andre Vorster · Thu, 07 Aug 2025 15:17:51 +0000

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] $RangeLow[RangeIdx] = High[BI – 1] $RangeIndex[RangeIdx] = RI ENDIF IF High[BI + 1] < Low[BI – 1] THEN RangeIdx = RangeIdx + 1 $RangeHigh[RangeIdx] = Low[BI – 1] $RangeLow[RangeIdx] = High[BI + 1] $RangeIndex[RangeIdx] = RI ENDIF NEXT IF DEBUG = 1 THEN DRAWTEXT(“Imbalance found: #RangeIdx#”, BarIndex[0], Low[0]) ENDIF // Remove mitigated imbalance FOR RI = 1 TO RangeIdx DO IF DEBUG = 1 THEN DRAWRECTANGLE($RangeIndex[RI] – 1, $RangeHigh[RI], $RangeIndex[RI] + 1, $RangeLow[RI]) COLOURED(0,0,200) //DRAWRECTANGLE($RangeIndex[RI] – 1, $RangeHigh[RI], $RangeIndex[RI] + 1, $RangeLow[RI]) COLOURED(0,0,200) ENDIF Valid = 1 FOR B = $RangeIndex[RI] + 2 TO TotalBars DO LB = Low[BarIndex[B]] HB = High[BarIndex[B]] // Candle is above or below our zone, ignore it IF LB >= $RangeHigh[RI] OR HB <= $RangeLow[RI] THEN IF DEBUG = 1 THEN DRAWTEXT(“Out”, B, High[BarIndex[B]]) ENDIF CONTINUE ENDIF IF LB <= $RangeLow[RI] THEN // Candle engulfs our zone, so imbalance is mitigated IF HB >= $RangeHigh[RI] THEN IF DEBUG = 1 THEN DRAWTEXT(“Mitigated”, B, High[BarIndex[B]]) ENDIF Valid = 0 BREAK ENDIF IF DEBUG = 1 THEN DRAWTEXT(“High”, B, High[BarIndex[B]]) ENDIF $RangeLow[RI] = HB ELSE // In this case, Low is within the zone IF DEBUG = 1 THEN DRAWTEXT(“Low”, B, High[BarIndex[B]]) ENDIF $RangeHigh[RI] = LB ENDIF NEXT IF Valid = 1 THEN DRAWRECTANGLE($RangeIndex[RI], $RangeHigh[RI], TotalBars+2000, $RangeLow[RI]) COLOURED(0,0,0,0) FILLCOLOR(173,194,201) //COLOURED(0,0,0,0) FILLCOLOR(173,194,201) //(0,0,0,30) 201,40,51 ENDIF NEXT ENDIF RETURN

Roberto.

FVG-00.itf = The original indicator.
FVG_Zones_TradeSignal.itf + FVG-Status.itf = Changes suggested by Ai to start AutoTrade when conditions are met.

The indicators does show but trade does not start when indicator is triggered.
It seems to work but I don’t understand coding to know what to change where to make it work. Each step with Ai sometimes become more complicated than getting clear development
(I’ve been in IT for many many years but in different sectors but code writing/understanding I can’t do)

See att pdf that’s copy of interaction with Ai.
You will understand it better than I do.
