Quantopian set_long_only() equivalent in Quantconnect?

I am porting code from quantopian to quantconnect. In quantopian, we can avoid negative holdings by using set_long_only(). I was wondering if there is any equivalence in quantconnect fo this?

Update Backtest








In Lean/QuantConnect API there is no equivalent for set_long_only().
I got this from Quantopian: "Robinhood only allows long. Orders that attempt to enter into a short position will be rejected by Robinhood. We strongly suggest you run your algorithms with the set_long_only trading guard to prevent you from accidentally running a strategy that depends on short positions."
When there is a brokerage restriction, we put it in the BrokerageModel for reality modelling in backtesting mode.
