Default and Minimum Size of an instrument

Imported from previous forum

Hi,

Through my application, i m able to set/change the default size and minimum size of an instrument.

My requirement is to send Security List Update Report [Message Type BK] whenever there is a change in default size and minimum size of an instrument.

i m using FIX.5.0

Can anyone help to provide the FIX fields for the following in the message type ‘BK’,
1.Default Size of an Instrument
2.Minimum Size of an Instrument
3.Indicative Default Size of an Instrument
4.Indicative Minimum Size of an Instrument

Thanks,
Christopher

FIX currently only knows the concept of a minimum/maximum order size for a security, tags 562 MinTradeVol and 1140 MaxTradeVol in component . This can be used to convey validation rules for incoming orders. I am not sure what you want to express with a default size. Do you want to submit orders without a size and have the value being populated by the receiver with the default value? Sounds safer to ask for an explicit value. I am a little lost with regards to the intention to having “indicative” minimum/default sizes. Is this about indicative quotes where you may have a different minimum size compared to firm (tradeable) quotes? What are the business processes behind this?
You may be able to use the block which has generic tags 871 InstrAttribType and 872 InstrAttribValue (871 allows user defined enum values).

we have same doubt Mr.Newman.Let we discuss about real time market, initial price and size of order must be specified this process must be done before NewOrderSingle request raise.From SecurityListUpdateReport(MsgTyp=BK) which fields help to set\get default values .

Thanks for your reply.
My application provides the following to the user,
Text box to input the Order Price
Text box to input the Order Size
Default size will be populated in the Order Size text box.

Indicative Minimum size and Indicative Default size are for Indicative Orders.

i will use the tag MinTradeVol[562] for minimum size.
Please help to provide the FIX field for Default size

I am not sure what you are trying to achieve. It sounds as if you want to populate fields in your GUI with default values coming from FIX fields. From where does the FIX message come that goes to the GUI and carries the default values as well as the min/max values? FIX messages are normally not targeted at input boxes of GUIs. FIXatdl has been developed for algorithmic trading to drive GUIs and obtain parameters for strategies. Maybe you are better served if you take at look at FIXatdl (http://www.fixprotocol.org/FIXatdl).
