How to limit the number of open trades

I cannot seem to limit the number of open trades. I have tried two methods to limit open trades to only one (1): Method 1 - sc.MaximumPositionAllowed Although I have the following line of code in the sc.SetDefaults section: sc.MaximumPositionAllowed = 1; the Trade Activity Log is showing thousands of open positions. (see the attached screenshot of my Trader Activity Log) This is occurring with a Single Chart replay in ver 1841. Method 2 - PositionQuantity in Buy and Sell code Following the documentation here: Automated Trading From an Advanced Custom Study: sc.GetTradePosition my code includes the following: s_SCPositionData PositionData;
sc.GetTradePosition(PositionData); int Quantity = PositionData.PositionQuantity; // Access the quantity ... // Buy Order if (Quantity == 0 && sc.CrossOver(Cross_CloseOrLow, LowOfDay) == CROSS_FROM_TOP) { Result = (int)sc.BuyOrder(NewBuyOrder); ... } The crossover works fine, but when I print out the Quantity in the Message Log, it is always showing as zero. Therefore the strategy keeps on buying. Note: Setting sc.AllowOnlyOneTradePerBar to true significantly reduces the number of trades, but I would like to get the above two methods working properly. Any suggestions on how I can get both Method 1 and 2 working? |

Try adding parentheses around the two parts of the AND statement: if ((Quantity == 0) && (sc.CrossOver(Cross_CloseOrLow, LowOfDay) == CROSS_FROM_TOP)) and see if that helps. Sometimes the logic isn't always what you want unless you are very explicit.
{ Result = (int)sc.BuyOrder(NewBuyOrder); ... } |

Thank you for the suggestion. But unfortunately adding parentheses did not help. I think the issue is that Quantity is not being populated or is being cleared by the time Buy and Sell is being called. Although I don't think it's necessary since Quantity should not be changing until it's called again, I did assign Quantity to a Persistent variable... but that didn't help either. The following is a snip-it code I am using: s_SCPositionData PositionData; sc.GetTradePosition(PositionData); int Quantity = PositionData.PositionQuantity; // Access the quantity int& Quantity_Persist = sc.GetPersistentInt(6); Quantity_Persist = Quantity; ... // Buy Order if ((Quantity == 0) && (sc.CrossOver(Cross_CloseOrLow, LowOfDay) == CROSS_FROM_TOP)) { Result = (int)sc.BuyOrder(NewBuyOrder); ... SCString DebugString; DebugString.Format("Quantity: %d, Quantity_Persist: %d", Quantity, Quantity_Persist); sc.AddMessageToLog(DebugString, 0); } |

We tested sc.MaximumPositionAllowed = 1; In the sc.SetDefaults code block and it did work properly: Auto-trade: Replay 60X: YMZ18 1 Min #1 | Trading Test 2 | BuyEntry | Bar start date-time: 2018-11-13 21:13:00.000 | BuyEntry signal is ignored because maximum Long Position quantity allowed has been reached or would be exceeded with new order. Max. Position allowed: 1. Resulting Position without working orders: 2. Resulting Position with all working orders except exits: 2. Resulting Position with Market working orders: 2 | 2018-11-14 01:48:26
