Particularities between Interactive Brokers and FOREX.com

[guillembm]

Hello,

I would like to switch from IB to FOREX.com. Are there any particularities between both brokers I should consider regarding to strategy programming to make the change?

Hello guillembm,

Thanks for your post.

Something to keep in mind when using Interactive Brokers is when using a NinjaScript strategy it is best practice to only work with passed by value data from OnExecution. Instances of multiple fills at the same time for the same instrument might result in an incorrect OnPositionUpdate, as sequence of events are not guaranteed due to provider API design. For an example on protecting positions with this approach, see OnExecutionUpdate().

This is seen on the OnOrderUpdate() help guide page linked below and applies to both Rithmic and Interactive Brokers users.

There are no specific notes in the help guide regarding creating NinjaScripts for FOREX.com.

All AccountItem parameters are valid for both and retrieve exactly the same information?

Hello guillembm,

Thanks for your notes.

The AccountItem values should be correct and retrieve the information you are accessing as listed in the help guide.

AccountItem: https://ninjatrader.com/support/help...ccountitem.htm

I am not aware of any AccountItem values that would be incorrect or not retrievable in a NinjaScript when using FOREX.com.
