Pre-trade data calculations

[jeronymite]

Before one submits an FX entry order of a known position size, how can one accurately calculate:

1. The commissions (entry and exit), based on commissions data entered into NT7 for the relevant instrument.
2. The margin that will be consumed, based on margin data entered into NT7 for the relevant instrument.

Thanks.

Hello jeronymite,

Thanks for your post.

Regrettably the information in not available through ninjascript. You would need to create variables to hold the information for commission and margin.

Thanks for your reply, Paul.

I understand that the data may not be available in a supported manner in NT7, but as one of your NT8 beta testers in this new age where NinjaTrader is being so helpful in identifying ways to do the "unsupported", I would be most grateful for the relevant magic to do this in an unsupported way, if it is at all possible for it to be done. Obviously, I will have no expectation of support for the unsupported.

Many thanks!

Hello jeronymite,

Thank you for your patience.

I am not aware of the exact means to do this, but I will look into this further.

Hello jeronymite,

Thank you for your patience.

Commission in NT 7: Instrument.MasterInstrument.GetCommission(1, Provider.Replay)
Here you type the Provider. and then select your data provider that you want the information from.

Margin in NT 7: Instrument.MasterInstrument.Margin

Please let me know if you have any questions.

Many thanks for looking into this, Patrick -- very much appreciated!

I can see that would work with just the MasterInstrument. How does one do this when one has many instruments added to the strategy? For example, I run with 28 Forex DataSeries added to my strategy and I want to be able to calculate on any of those prior to trade submission on the relevant instrument.

Many thanks!

You would use Instruments[barsInProgress Index] in place of Instrument. For example:

Instruments[1].MasterInstrument.Margin

Many thanks, Patrick!

One last question, if I may: Given that GetCommission requires a Provider, how can one determine the Provider of the current strategy?

I can obtain the Connection name, status, adapter, etc ... but Provider?

Thanks again!

On further investigation, I believe it should be:

Account.Connection.Options.Provider

Grateful for your confirmation, Patrick. Thanks!

[NinjaTrader_PatrickH]

That would be correct.

Instrument.MasterInstrument.GetCommission(1, Account.Connection.Options.Provider)
