Sierra Charts Coding

[viamal 10]

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!

i use SC, but i dont code in C++

 

What you are wanting to do here might be easily acheiveable (and simpler for a non coder) using their spreadsheets for trading AS WELL AS attached orders (with each entry having easily adjustable take profits and stop loss orders associated with the original entry)
