Share New Research 
Hello,
Thanks for anyone who can help. Its really much appreciated :)
I have a Parabolic SAR algorithm. If PSAR < Price, I want it to buy with a limit order 2 cents above current price--
if self.Portfolio["TCMD"].Quantity <= 0 :
if self.psar.Current.Value < self.Securities["TCMD"].Price:
self.Log("BUY >> {0}".format(self.Securities["TCMD"].Close))
self.LimitOrder(self.forex.Symbol, 1, ( self.Securities["TCMD"].Price + .02))
This triggers Lean to send a limit order in for 1 share, once every minute, for the rest of the day. I end up with 24 shares after I realise, all orders for 1 share each.
Can someone help me so that it doesnt spam orders?
Thanks for any and all help-

Hey Christian,
If a limit order is not filled right away, the algorithm needs to know that a limit order has already been placed. We can use self.ticket to keep track of our limit order. (i.e. If self.ticket is not None there is a limit order placed and if it is None, there is no limit order.) We could also have used a boolean to accomplish the same thing, but this method also lets us control the attributes of our limit order after its been placed if we need to.
class MyAlgo(QCAlgorithm): def Initialize(self): self.SetStartDate(2019, 11, 20) #Set Start Date self.SetCash(200) #Set Strategy Cash equity = self.AddEquity("TCMD") equity.FeeModel = ConstantFeeModel(.02) self.symbol = equity.Symbol self.psar = self.PSAR(self.symbol, .005, .005, .05) self.ticket = None # define a small tolerance on our checks to avoid bouncing def OnData(self, data): holdings = self.Portfolio[self.symbol]; price = holdings.Price if (self.ticket is None and holdings.Quantity <= 0 and self.psar.Current.Value < price): self.ticket = self.LimitOrder(self.symbol, 1, price + .02) if (self.ticket is None and holdings.Quantity > 0 and self.psar.Current.Value > price): self.ticket = self.LimitOrder(self.symbol, -1, price - .02) def OnOrderEvent(self, orderEvent): if orderEvent.Status == OrderStatus.Filled and orderEvent.OrderId == self.ticket.OrderId: self.ticket = NoneBest,
