Hi, I have developed custom chart based on -BID_ASK_TRADE_SYNC data. Chart works quite fine and do exactly what I need. But I have discovered: I actualize Last but there is no "white box" showing actual Last price on Y axis. I'm not able to attach Market Depth Historical Graph to this chart. What do I need to change to solve this? If I try to attach Market Depth Historical Graph Message Log shows: "Custom DLL Study DateTime: Out of bounds array error at Index 7866 (it looks like last Index). How can I solve this? Thank you. SCSFExport scsf_MyCustom(SCStudyInterfaceRef sc)
{ SCSubgraphRef Open = sc.Subgraph[0]; SCSubgraphRef High = sc.Subgraph[1]; SCSubgraphRef Low = sc.Subgraph[2]; SCSubgraphRef Last = sc.Subgraph[3]; . . . if (sc.SetDefaults) { // Set the defaults sc.GraphName = "My Graph"; sc.AutoLoop = 1; sc.IsCustomChart = 1; // true sc.GraphRegion = 0; // First region sc.DrawZeros = 0; // false sc.StandardChartHeader = 1; // true sc.DrawZeros = 0; sc.FreeDLL = 1; // HIGH/LOW subgraf: High.Name = "High"; High.DrawStyle = DRAWSTYLE_STAIR; High.PrimaryColor = RGB(70, 70, 70); Low.Name = "Low"; Low.DrawStyle = DRAWSTYLE_STAIR; Low.PrimaryColor = RGB(70, 70, 70); Last.Name = "Last"; Last.DrawStyle = DRAWSTYLE_STAIR; Open.Name = "Open"; Open.DrawStyle = DRAWSTYLE_IGNORE; Open.PrimaryColor = RGB(70, 70, 70); . . . // inputs: sc.Input[0].Name = "pouze vetsi nez"; sc.Input[0].SetInt(0); . . . return; } if (sc.UpdateStartIndex == 0){ sc.ResizeArrays(1); } // persist vars: int& k = sc.GetPersistentInt(0); int& idx = sc.GetPersistentInt(1); . . . // first values: if (sc.Index == 0){ sc.DateTimeOut[0] = sc.BaseDateTimeIn[sc.Index]; Open[0] = sc.BaseDataIn[0][sc.Index]; Low[0] = sc.BaseDataIn[2][sc.Index]; High[0] = sc.BaseDataIn[1][sc.Index]; Last[0] = sc.BaseDataIn[3][sc.Index]; idx = 0; } // actualization: if (sc.Index > 0) { sc.DateTimeOut[idx] = sc.BaseDateTimeIn[sc.Index]; Open[idx] = sc.BaseDataIn[0][sc.Index]; Low[idx] = sc.BaseDataIn[2][sc.Index]; High[idx] = sc.BaseDataIn[1][sc.Index]; Last[idx] = sc.BaseDataIn[3][sc.Index]; Last.DataColor[idx] = sc.Input[10].GetColor(); } // new bar condition: if () { // add bar: sc.AddElements(1); // ++ custom index for next use: idx++; // reset other persist vars: k = 0; . . . } } Date Time Of Last Edit: 2017-02-14 13:54:17

You cannot use the Market Depth Historical Graph study on a custom ACSIL chart.

Are you sure? I tried to apply Market Depth Historical Graph to your example of custom chart called Copy of Base Graph and it works fine. In my custom chart i got in to situation, when Market Depth Graph is not fixed to price (screen attached). There is no error in message log after sc.GraphDrawType = GDT_OHLCBAR. You have no advice what should be missing to fix that Market depth Graph to actual price? |

Make sure the Scale Range for all of the studies in Chart Region 1 are set to Automatic: http://www.sierrachart.com/index.php?page=doc/Scaling.html#ScaleWindowStudy Sierra Chart Support - Engineering Level Your definitive source for support.

Is it still the case that one cannot use the Market Depth study on a custom chart or is there a method to do this? The suggestion to use the Automatic scale range seems to imply it may be possible?
