Hello,
I tried cloning the Sentiment and style Rotation strategy, it gave quite decent results up until Jan 2018 where there is a huge drop in equity. Could anyone please help me to figure out the cause?
Thanks!

Hey Prashant,
The massive drop in equity is caused by a buggy trade which occurred on 01-03-2018.
Time: 2018-01-03 00:00:00, Ticker: DISCB, OrderType: Buy Market On Open, FillPrice: $199,999.95 USD, Quantity: 45, Status: FilledThis order for the ticker DISCB fills for 45 shares at $199,999 dollars per share. However, the price of DISCB at that time is $26.20 per share. This causes a massive drop in the value of your portfolio, putting your account into a margin call. We are investigating this issue; for now you can work around this error by reducing the size of your universe. Instead of selecting all equities with fundamental data, you can select the top 1000 most liquid ones. You can use Universe.Unchanged to signal to your algorithm that no changes need to made to the universe.
def CoarseSelectionFunction(self, coarse): if self.month_start: # drop stocks which have no fundamental data or have low price fundamentals = [x for x in coarse if (x.HasFundamentalData)] sorted_fundamentals = sorted(fundamentals, key=lambda k: k.DollarVolume, reverse=True) self.filtered_coarse = [x.Symbol for x in sorted_fundamentals][:1000] return self.filtered_coarse else: return Universe.UnchangedBest
