We now have full margin modelling! This makes QuantConnect more realistic than ever, giving you a dynamic amount of leverage depending on the model parameters. We have modeled margin calls so if you get some unexpected sells its because your algorithm is over leveraged and losing money!
Traditional brokerages give you 2x leverage, and 4x intraday. For simplicity we use 2x constantly. If your algorithm is ever fully leveraged and the price of the market drops - you'll be given a 10% buffer to correct your portfolio. If they aren't corrected your algorithm will have margin call orders placed against it! You can see the orders tagged with "Margin Call" flag in the trades tab.
We're super proud of how QuantConnect is evolving. Its becoming incredibly realistic and matches the behavior you'll see in live trading!

Is there any way to disable the margin calls feature?
For example, I have enconutered a situation when I am getting margin calls because of the bad data. In this situation it would be easier just to disable the feature instead of working around the bad data,
A specific example - reverse split adjusted prices are not always correct

Found this
Securities["XIV"].SetLeverage(1m);

We can disable margin calls by setting the margin call model to the NullMarginCallModel.
This can easily be done like this:
Securities["XIV"].MarginModel = MarginCallModel.Null;

Thanks

Securities["XIV"].MarginModel = MarginCallModel.Null;This no longer seems to work. This returns an error saying you can't implicitly convert type IMarginCallModel to ISecurityMarginModel. Is there another way to disable margin calls?

Please try to disable margin calls at Portfolio level using:
// In Initialize
Portfolio.MarginCallModel = MarginCallModel.Null;
0
Are the MarginCallModel.Null overrides still applicable? Maybe I need a Python version of the code.
I've tried
Securities["XIV"].MarginModel = MarginCallModel.Null
and
Portfolio.MarginCallModel = MarginCallModel.Null
Both return errors, "global name 'Securities' is not defined" and "global name 'Portfolio' is not defined" respectively.
Thanks to anyone who can help me eliminate the Quantconnect 2x leverage limit. QC team, may I humbly suggest this should only apply to backtests, not live trading.

Did you not forget self. before both Securities and Portfolio?

Algo doesn't allow > 2x leverage with
self.Portfolio.MarginModel = MarginCallModel.Null
or
self.Portfolio.MarginModel = PatternDayTradingMarginModel()
The goal is to set 4x leverage intraday like a normal brokerage account... and ideally override QC limits completely to trade a portfolio margin account. Thanks!

From Docs:
self.Securities["AAPL"].MarginModel = PatternDayTradingMarginModel()

Thanks guys! Both MarginCallModel.Null and PatternDayTradingMarginModel() working now. Had reversed them, and placed too early in the code sequence. Posted in backtest below for others. In list form looks like this:
# Add securities and indicators
self.bonds = ["SHY","IEF"]
for s in self.bonds:
self.AddEquity(s, Resolution.Minute)
self.Securities[s].MarginModel = PatternDayTradingMarginModel()
Can I relax overnight leverage constraints beyond 2x? A Portfolio Margin account (next level up from Reg-T) at IB and other prime brokers will allow more than 2x leverage, especially if you're holding bonds and forex, both of which have low volatility.
It would be great to have a way to opt out of QC leverage constraints, especially for live trading.

Hi Brett, the default is IB's 2x margin accounts. If you want 4x intraday margin limits, you can use the PatternDayTradingMarginModel, This documentation explains the margin model in greater details.
You can also set the leverage for each stock with self.Securities[symbol].SetLeverage()
Please see this example
