[Programming Help] - Footprint Chart - Indicator for imbalance

I am using a footprint chart and at the bottom I have added the buyer/seller imbalance amount (red/green) for each candle. Is there a way to add an indicator when the buyer/seller imbalance is does not correlate with the direction of the candle? I want to see when for instance I have buyer imbalance but I have a down red candle.

There may well be a way to do it with vanilla Sierra but its trivial to write something of your own. This takes the delta subgraph (SG1) of a number bar calc values study on the FP chart as an input to get the delta and plots an up arrow if a HH is made (since the last up bar) on the current up bar with negative delta and vice-versa. You could just remove the HH,LL (eg. sc.High[Index] > sc.High[Index-2]) checks for your case. EDIT: I should have added I use P&F so you will have to use another direction indicator method (which I can't remember currently) than PF_DIRECTION_ARRAY. SCSFExport scsf_DeltaDivergence(SCStudyInterfaceRef sc) { SCSubgraphRef OutputDown = sc.Subgraph[0]; SCSubgraphRef OutputUp = sc.Subgraph[1]; SCInputRef NumBars = sc.Input[1]; SCInputRef Offset = sc.Input[2]; if (sc.SetDefaults) { sc.AutoLoop = 1; sc.GraphName = "Delta Divergence"; sc.GraphRegion = 0; OutputDown.Name = "Down Divergence"; OutputDown.DrawStyle = DRAWSTYLE_ARROW_DOWN; OutputDown.PrimaryColor = RGB(255, 0, 0); OutputUp.Name = "Up Divergence"; OutputUp.DrawStyle = DRAWSTYLE_ARROW_UP; OutputUp.PrimaryColor = RGB(0, 255, 0); NumBars.Name = "Num bars calc values study"; NumBars.SetChartStudySubgraphValues(sc.ChartNumber, 13, 1); Offset.Name = "Bar offset (ticks)"; Offset.SetFloat(0.05f); return; } SCFloatArray Delta; sc.GetStudyArrayFromChartUsingID(NumBars.GetChartStudySubgraphValues(), Delta); if (sc.BaseData[PF_DIRECTION_ARRAY][sc.Index] == 1) { OutputDown[sc.Index] = sc.High[sc.Index] > sc.High[sc.Index - 2] && Delta[sc.Index] < 0 ? sc.High[sc.Index] + Offset.GetFloat() : 0; } else { OutputUp[sc.Index] = sc.Low[sc.Index] < sc.Low[sc.Index - 2] && Delta[sc.Index] > 0 ? sc.Low[sc.Index] - Offset.GetFloat() : 0; } } Date Time Of Last Edit: 2022-06-16 09:00:41

User431178: I like you're chart and I'm not much of a programmer. Is there an easy way to add a total volume to each candle in your chart?

Modified chart to show volume below bar and delta above.

User431178 How do I change the color of the candlestick outline in the footprint? Up is blue and down is pink, and I want a green and red outline.

You can find the info about number bars at these links https://www.sierrachart.com/index.php?page=doc/NumbersBars.php#s328 Numbers Bars: Drawing Open to Close Boxes on Side of Numbers Bar The particular settings are Open Marker / Up Box Color and Close Marker / Down Box Color |
