How to use portfolio percentage/currentholdings for stopmarket and limit methods

 Edit: I found  a solution using -self.Portfolio[symbol].Quantity

Hi Victoria Butler ,

If you want to place the three orders in sequence. I would recommend using:

quantity = self.CalculateOrderQuantity(symbol, 0.2)
if quantity != 0:
    self.MarketOrder(symbol, quantity)
    self.StopMarketOrder(symbol, -quantity, stop_price)
    self.LimitOrder(symbol, -quantity, limit_price

because -self.Portfolio[symbol].Quantity is right after the SetHoldings order is filled which is an asynchronous operation in live mode, so we can have:

self.SetHoldings(symbol, 0.2)
quantity = self.Portfolio[symbol].Quantity   # <-- quantity is zero and the following orders will be invalid
self.StopMarketOrder(symbol, -quantity, stop_price)
self.LimitOrder(symbol, -quantity, limit_price

This will work well in backtesting mode since the orders are filled synchronously and market orders (created by SetHoldings) are filled immediately.

Best regards,
Alex
