Backtesting strategy on futures

[xToast]

Hello,
I made a strategy myself that includes some sort of position sizing algorithm. When running the strategy on stocks everything works perfect using Close[0] as current price, but when I run it on futures, I woud have to know the margin and not the real value of the contract.
Is there any way to check if the traded contract is a future and if it is, to access its margin?

You can use : Instrument.MasterInstrument.InstrumentType

MasterInstrument.Margin and MasterInstrument.Margin2 are unsupported, but you are free to try them out.
