Editing Instruments
| |
The Instrument Editor displays all parameters that define an instrument including symbol mappings to your connectivity provider and symbol level commission values. The editor allows you to change or add parameters to an instrument's profile. In general, instruments that are installed with NinjaTrader do not require any parameter modification. However, you may want to override your global commission settings if a particular symbol has a unique commission structure.
In the Instrument Manager, once an instrument is selected in the instrument grid, you can double click or press the "Edit" button to open the Instrument Editor.

The definition tab displays parameters that uniquely define an instrument.

Misc Parameters
The misc tab allows you to set instrument level commission settings, symbol mapping, split and dividend information.
Commission Section
Instrument level commission values override global commission settings. An example would be if you have a standard commission rate from your broker for most instruments but there may be an exception where your rate is different for the DOW Emini contract. You would then set the custom DOW Emini contract commission rate at the instrument level. Please review the following help section to understand how to manipulate commission values.
Symbol Mapping
If you add a new instrument that is not already in the NinjaTrader instrument database you will need to map the new instrument to the symbol used for the connectivity provider (broker or data feed) that you will be requesting data from. Most instruments in the database are already mapped.
NinjaTrader will split and dividend adjust historical chart data based on the information defined per instrument and if options are enabled to do so. Some market data providers provide already adjusted data while others do not. Please see the following help instructions for adding split and dividend data to an instrument.
