Hi, I'm having issues reading all orders each time a study function is called. If I place some orders and start the study the code below can see the orders, but only once on the first call to the study function. If I place a new order while the study is running, the code doesn't see the newly added order? The following study code is called every second when enabled on a chart. I expected it to print all the orders as they are placed but it doesn't. It only prints the orders on the first startup call to the function. I'm I missing some extra step? TIA SCSFExport scsf_TradeCopierFunction(SCStudyInterfaceRef sc) { int orderIndex = 0; while(true) { s_SCTradeOrder order; if(sc.GetOrderForSymbolAndAccountByIndex(EMPTY_STRING, tradeAccount, orderIndex, order) < 0) break; orderIndex++; // code that prints details about each order } } Date Time Of Last Edit: 2025-02-21 19:51:50

Try adding sc.UpdateAlways = 1; and using sc.GetOrderByIndex() instead. Something like this: SCSFExport scsf_TradeCopierFunction(SCStudyInterfaceRef sc)
{ sc.AutoLoop = 0; sc.UpdateAlways = 1; int orderIndex = 0; while (true) { s_SCTradeOrder order; //next order if (sc.GetOrderByIndex(orderIndex, order) == 0) { break; } //order info SCString msg; msg.Format("Order #%d | Account: %s | Symbol: %s | Qty: %d | Type: %d | Status: %d | Price: %.2f", orderIndex, order.TradeAccount.GetChars(), order.Symbol.GetChars(), order.Quantity, order.OrderType, order.OrderStatusCode, order.Price1); sc.AddMessageToLog(msg, 1); orderIndex++; } } Date Time Of Last Edit: 2025-02-19 19:17:28

and using sc.GetOrderByIndex() instead
That works great but it only get orders for the symbol on the chart. For example I have 2 orders open: EURUSD and BTCUSD... the study is on the EURUSD chart and only orders happening for EURUSD are being seen by the code. UPDATE: I just rebuilt everything and restarted SierraChart and changed my original code... SCSFExport scsf_TradeCopierFunction(SCStudyInterfaceRef sc) { int orderIndex = 0; while(true) { s_SCTradeOrder order; if(sc.GetOrderForSymbolAndAccountByIndex(EMPTY_STRING, tradeAccount, orderIndex, order) < 0) break; orderIndex++; // code that prints details about each order } } to use this from your example... while(sc.GetOrderForSymbolAndAccountByIndex(EMPTY_STRING, tradeAccount, orderIndex, order) != SCTRADING_ORDER_ERROR)
and now it works... I get all order actions for all symbols on one chart. Thanks Date Time Of Last Edit: 2025-02-19 20:52:14

UPDATE: I'm back to square one... today I noticed the "sc.GetOrderForSymbolAndAccountByIndex(...)" function will all of a sudden just stop looping through market orders that are only a few seconds old. If I play around with the chart update interval setting the orders will start looping again but that solution only seems to work for a while. Anyone have any possible ideas why that is happening? Perhaps some flag that needs to be set in the default section of the study? TIA Date Time Of Last Edit: 2025-02-21 19:56:27
