Hello,
I'm not sure why this algorithm is sending so many 1, -1, and other small orders. Do you now how I can stop those small orders from trickling through?
Thanks!

Hello Sean
The order quantity depends on the cash in hand, the unit price for target securities, and the number of securities in the basket. To increase cash in hand, we could change
self.SetCash(100000)toself.SetCash(1000000). In order to choose securities with lower unit prices, we can add conditions to screen out securities with a price of less than $100. We could also limit the number of target securities from 100 to 50. These two goals can be achieved by updating code inself.CoarseSelectionFunction:sortedByDollarVolume = sorted(coarse, key=lambda x: x.DollarVolume, reverse=False) filtered = [ x.Symbol for x in sortedByDollarVolume x.Price < 100] return filtered[:50]Please check this page for more variation about universe selection.
I attached a backtest updating the code provided for the demonstration. Hope this could help.
Best,
Yuxin Guan

Hi Yuxin,
Thank you for your response! I'm OK with the SetCash and the price of the securities being traded. The question I was actually wondering about is why I'm seeing so many orders like these in the above backtest:
2020-05-18T13:59:23ZCCL14.43-4MarketFilled-57.722020-05-18T13:59:23ZUAL22.71-1MarketFilled-22.71From what I understand, 3% is the default portfolio percent allocated to each insight or order with the "AccumulativeInsightPortfolioConstructionModel." But the total value of each of these trades is $57 or $22, very very far below that 3% default portfolio percent. Do you know why the algorithm is sending orders so far below that 3% default?
Thanks,
Sean

Hi Yuxin,
Sorry those two example orders didn't come through correctly! The two example orders that you can see if you clone the above algorithm are these:
Time Symbol Price Quantity Type Status Value
2020-05-18T13:59:23Z CCL 14.43 -4 Market Filled -57.72
2020-05-18T13:59:23Z UAL 22.71 -1 Market Filled -22.71
Thanks,
Sean

Hi Derek,
Ah OK I missed the fact that this PCM also rebalanced every time a new insight is generated. Thank you so much as always!
Thank you,
