Hello, I am creating a new algorithm that uses the MACD indicator, but I would like to use Energy ETF Basket Universe Module from the algorithm creator through "self.SetUniverseSelection(VolatilityETFUniverse())" in the Initialize method.
How do I get the indicator to get the MACD values on each individual stock in the Universe, and then how do I reference that in OnData? Here is a sample:
def Initialize(self):
self.SetStartDate(2021, 1, 1)
self.SetCash(1000000)
self.SetExecution(ImmediateExecutionModel())
self.SetRiskManagement(MaximumDrawdownPercentPerSecurity(0.05))
self.UniverseSettings.Resolution = Resolution.Minute
self.SetUniverseSelection(VolatilityETFUniverse())
self.mac = self.MACD(*symbols*, 12, 26, 9, MovingAverageType.Exponential, Resolution.Minute)
def OnData(self, data):
if self.mac.Current.Value < 1:
self.SetHoldings(*symbols*, .1)What exactly do I have to put in place of *symbols* ? Do I have to do something like create a variable and set it equal to the Universe, then reference it with variable.Symbol?
Thanks for the help

Hi Ethan and Jackson,
To setup an indicator on each security in a dynamic universe, we should:
Refer to this Strategy Library tutorial for an example.

Derek,
Thank you for the links and tutorials! I am sure they will be handy. Athough, of the examples you gave me seem to be specified for custom indicators that need to be updated to work. For indicators such as self.MACD, it says they update automatically. How exactly could I get the self.MACD or any automatically updating indicator to accept a universe of symbols instead of just one and perform it's calculations on every symbol on that collection/universe, making trades accordingly? Do I just follow all the steps from the examples you've given but ignore anything that has to do with updating? Or maybe for something like that will I have to manually create the MACD indicator so I can copy the format of the examples?

Hi Jing Wu, Just a quick question: Why is this algo waiting for a month and starting to run from a second month? Is it for warming up? Can we modify this algorithm to run from the first month? Just remove the flags? Please let me know. Thank you.

Thank Jing.
market cap = Shares Outstanding * Price = Shares Outstanding * (Earnings Per Share * PE ratio)
That's what I was waiting for. It's a huge improvement for my algo.

Hi Jing Wu,
1. I ran the Algo, and found the exit function(when current SPY price is lower than last N-day moving average price, then liquidate all the open positions and buy TLT.) doesn't work all the time. The exit function doesn't work, making it performs bad on crisis.
The momentum strategy has relatively higher volitility. I think one of the drawback of momentum strategy is failing to act quickly to close a bad position. I'm considering to add a Stop Market Order of the portfolio composite seperately. However, I'm new to do an alogo with python, after reading the Documentation and browing the internet, I only learned how to add StopMarket order while making market order, like this:
self.MarketOrder(self.baba, 300)
self._stopMarketTicket = self.StopMarketOrder(self.baba, -300, slice['BABA'].Close * Decimal(0.95), "stop market")
This algo's code seems complex to me, I can't find the place to get the price and deploy the StopMarket order.
Can you give me some instructions on this problem?
2. I want to test the algo with leverage, for example, 1.5 leverage then I modify LINE 96:
weight = 0.99/len(chosen_df)
for symbol in chosen_df.index:
self.AddEquity(symbol)
self.SetHoldings(symbol, weight)
I change 0.99 to 1.5, but it doesn't work. Do you know how to set the weight here?
Thank you a lot.

I have sprinkled a bunch of debug lines in the code just to analyze the behavior and I have noticed that if I set the following dates:
SetStartDate(2004, 1, 1); SetEndDate(2004, 4, 1);...the value for the "symbols" variable in "FineSelectionFunction" gets assigned on 01/03/2004 only to be used by the "rebalance" function a month later, 02/02/2004. This tells me that the rebalance is operating on a fine "symbols" list that is a month old. Is this intentional?
One other behavior that I have noticed is that the "CoarseSelectionFunction" and "FineSelectionFunction" never gets called on the "MonthStart" day. In my example date window, it never gets called on 01/02/2004. Is the "MonthStart" schedule somehow interfering with the Coarse and Fine events?
Thanks!

Hi Xi Liu,
You can use self.StopMarketOrder() everywhere in your algortihm. For the stop price, you can use
"self.Securities["BABA"].Close" * Decimal(0.95) instead of "slice['BABA'].Close * Decimal(0.95)" because you can only get the slice data in OnData() method.

Hi Jing Wu, I cloned your new method (for Market Cap) algo and ran for 2015 to March 1st of 2018. I found that the leverage went up to 500% (5x) in the early 2016 and came down to 300% (3x) in the end of this backtest period. You set the maximum weight to 0.99x as below. I guess something should be fixed. Can you take a look and fix the leverage control (e.g. maximum 2.0x)? Thank you.

Hi Jing Wu,
I ran this today 4/2/2018 and was looking for the trade signals to occur by 10am PST since that seems to be the time the trades occur in the backtesting. Do we need to wait until end of first day of the month or should the signals be there by 10am PST, or another time?
When setting this up for trading live what types of alterations might need to be made? Is there a page/link that describes this or is this something support helps with after creating a live account?
Thank you!

Jing Wu,
Also seeing errors like this:
Backtest Handled Error: The order quantity for TLT cannot be calculated: the price of the security is zero.Doesn't look like April 2018 TLT trade is getting executed because of it. Could it be that the algo is looking at the first of the month for the price but isn't seeing it because the first falls on a weekend?

Hi, Jing, I am new to QuantConnect so a little confused on your code.
it seems that you do everything on Intialize() and pass on OnData(), does it mean Initialize() will run many times instead of just setting the initialial condition?

I'm a little bit confused by the code snippet below. We check the moving average exit gate, and if it shuts, we loop through each position, if it's not TLT (bonds), then we exit the position. That makes sense.
if self.Securities[self.spy].Price < spy_hist.mean(): for symbol in self.Portfolio.Keys: if symbol.Value != "TLT": self.Liquidate()But, when we use self.Liquidate() and don't specify a security, doesn't it just liquidate every single position in the portfolio? Why bother to loop through the Portfolio keys at all, if we are just going to liquidate everything anyway? In my head it seems that self.Liquidate(symbol) or self.Liquidate(symbol.Value) would make more sense. Can someone tell me what I am missing?

Wei Chian Ong, what the code Liquidate() will do is possibly more tricky than you imagined. I suggest you check the code inside ideally debug carefully by using VS.

Wei Chian Ong
Thanks for the reply. I've had a look at your previous post regarding the self.Liquidate() method, and my question probably doesn't run as deep as the intricacies of dark pools and slippage in actual trading. It's more of a question regarding the coding itself. The documentation and this forum post and reply seem to indicate that using self.Liquidate() without a security specified, will liquidate all positions, and I was having trouble understanding why we bother looping through each symbol in the portfolio and checking if it's not treasury bond ETF, if we go ahead and liquidate everything anyway, would it not make more sense to use self.Liquidate() with the actual position we are currently looping through?

I was not meaning dark pools. I was just saying we should look inside the detail codes of Liquidate() in VS if there is something confused.

I'm not familiar with how to use visual studio (I assume that's what VS stands for), so I'll have to try it using log or debug calls.

I cloned this algorithm and received an error "Invalid Token" on the self.SetStartDate function, so am unable to run or backtest. Is anyone receiving this same error? Is there an easy fix?

I think I kept getting the same Nick and I wasn't sure why either. I deleted the code for the self.SetStartDate and self.SetEndDate and then re-typed them manually in case it was a whitespace issue or something (probably a very inefficient way to do that anyway). Same problem, but I repeated that several times and eventually it worked. Not a very scientific response to your question .......

The invalid token is from python 2.7 to python 3.6 upgrade. Since python 3.6 numbers can't be prefixed with 0 -- e.g. "01"
If you cloned an old backtest it can have dates with 2001, 01, 01 etc.
