Hi, I am trying to buy stock using a market order, and then have a stop-loss using a stop market order if the price goes at or below a certain price. As I understand from this post:
https://www.quantconnect.com/forum/discussion/8514/stop-market-order-not-triggered-in-backtest/p1a MarketOrder() using a positive number of shares followed by a StopMarketOrder() with a negative number of shares and a stop price below the current price, should be used. However, when I implement this in my code it seems to purchase the stock and then immediately sell the stock, despite the current price being above the stop price. Would someone know what the issue is? Thanks.

I think I was misreading the Orders tab results actually, it may be working as intended. Couple other bugs but seem unrelated. Not sure how to delete Discussion posts, sorry.

Hi Dahui,
The orders are working as intended. However, it appears to be exiting so quickly sometimes because the algorithm can place trades shortly after the market open. At that point in time, the LOD is very close to the entry price.
The algorithm could be improved by removed AddEquity from the CoarseSelectionFunction. The algorithm automatically subscribes to the symbols returned from this method, so AddEquity is not necessary.
In addition, when creating indicators for securities in a dynamic universe, we should use the full class name (VolumeWeightedAveragePriceIndicator, ExponentialMovingAverage) instead of the helper methods. See the EmaCrossUniverseSelectionAlgorithm for an example.
Lastly, the `isMarketHours` method can be replaced with our IsMarketOpen method, which accounts for shortened trading days.
Best,
