Dear All! I'm currently trying to implement an automated trade strategy into a custom study DLL. Unfortunately, I have no C++ experience at all. I have spent the whole day reading the sierra chart help guide on programming, but I am still a bit confused. The question I have will be very simple for someone who has done any coding in Sierra Chart. Here we go: In my initial study I have 2 lines crossing and giving buy or sell signals. Now this will cause "endless" trading, because you are always in a position. All i want is to implement a take profit/stop loss condition to my strategy so that the position could be closed not only when the lines cross, but when a stop or take limit has been reached. Ideally, I would like to make stop/take size and order size changeable in Study options, without the need to tweak the code. Sierra Chart have the following example of a study where 2 lines cross, but it does not contain the stop/take orders.. SCSFExport scsf_SC_TradingCrossOverExample(SCStudyGraphRef sc) { SCInputRef line1Ref = sc.Input[0]; SCInputRef line2Ref = sc.Input[1]; SCSubgraphRef bullish = sc.Subgraph[0]; SCSubgraphRef bearish = sc.Subgraph[1]; if (sc.SetDefaults) { // Set the configuration and defaults sc.GraphName = "Trading CrossOver Example"; sc.StudyDescription = "An example of a trading system that enters a new position or \ reverses an existing one on the crossover of two study Subgraphs. \ When line1 crosses line2 from below, the system will look to be long. \ When line1 crosses line2 from above, the system will look to be short."; sc.AutoLoop = 1; // true sc.GraphRegion = 0; sc.FreeDLL = 0; sc.CalculationPrecedence = LOW_PREC_LEVEL; line1Ref.Name = "Line1"; line1Ref.SetStudySubgraphValues(1, 0); line2Ref.Name = "Line2"; line2Ref.SetStudySubgraphValues(1, 0); bullish.Name = "Bullish"; bullish.DrawStyle = DRAWSTYLE_POINTHIGH; bullish.LineWidth = 3; bearish.Name = "Bearish"; bearish.DrawStyle = DRAWSTYLE_POINTLOW; bearish.LineWidth = 3; sc.AllowMultipleEntriesInSameDirection = false; sc.MaximumPositionAllowed = 5; sc.SupportReversals = true; // This is false by default. Orders will go to the simulation system always. sc.SendOrdersToTradeService = false; sc.AllowOppositeEntryWithOpposingPositionOrOrders = false; sc.SupportAttachedOrdersForTrading = false; sc.CancelAllOrdersOnEntriesAndReversals= true; sc.AllowEntryWithWorkingOrders = false; sc.CancelAllWorkingOrdersOnExit = true; sc.AllowOnlyOneTradePerBar = true; sc.MaintainTradeStatisticsAndTradesData = true; return; } // only process at the close of the bar; if it has not closed don't do anything if (sc.GetBarHasClosedStatus() == BHCS_BAR_HAS_NOT_CLOSED) { return; } // using the line1Ref and line2Ref input variables, retrieve the subgraph arrays into line1, // line2 arrays respectively SCFloatArray line1; sc.GetStudyArrayUsingID(line1Ref.GetStudyID(), line1Ref.GetSubgraphIndex(), line1); SCFloatArray line2; sc.GetStudyArrayUsingID(line2Ref.GetStudyID(), line2Ref.GetSubgraphIndex(), line2); // code below is where we check for crossovers and take action accordingly if (sc.CrossOver(line1, line2) == CROSS_FROM_BOTTOM) { // mark the crossover on the chart bullish[sc.Index] = 1; // Create a market order and enter long. s_SCNewOrder order; order.OrderQuantity = 1; order.OrderType = SCT_ORDERTYPE_MARKET; sc.BuyEntry(order); } if (sc.CrossOver(line1, line2) == CROSS_FROM_TOP) { // mark the crossover on the chart bearish[sc.Index] = 1; // create a market order and enter short s_SCNewOrder order; order.OrderQuantity = 1; order.OrderType = SCT_ORDERTYPE_MARKET; sc.SellEntry(order); } } } Can anyone help,please? Very much appreciated!
