I just started using QuantConnect recently, and I must say it's one of the best cloud platform I've used. However I'm finding it difficult to understand the S⊤MarketOrder stop order. Let's say I'm holding 500 shares of SPY, and I want to close the position immediately SPY reaches a particular price
self.StopMarketOrder(self.spy.Symbol, -500, 0.90 * self.Securities[self.spy.Symbol].Close)
When the stop price is triggered, does it close the position or it SELL/SHORT it. ?

Hi Seine,
The second statement does not work because it is comparing `self.momfiveDayWindow[0]` (which is of type IndicatorDataPoint) with a float. We can get the float value of `self.momfiveDayWindow[0]` by calling `self.momfiveDayWindow[0].Value`. Thus, a working statement would read
Share New Research 
long_signal_1 = self.momfiveDayWindow[0].Value > float(0)In addition to that error, the algorithm was also running into issues with checking the `self.ticket.Time` while `self.ticket` was set to `None`. We can resolve this by ensuring
self.ticket is not Nonebefore checking `self.ticket.Time`.
See the attached backtest which has both of these issues resolved.
Best,
Derek

Hi Obimba,
If you hold 500 SPY, it will sell your 500 SPY. A negative quantity is selling, a positive one is buying. If you sell something you do not hold, you are short selling. It will put you in a negative position (-500 SPY for instance). Then, when you buy back 500 SPY, you'll reach 0 and you will then exit your short position.
In an nutshell…

Thanks for your reply. But I'm still not getting it.
I'm trying to update my ‘MarketOrder’ ticket to a new stop loss: that's exciting the position
