Re: Default and Minimum Size of an instrument
Christopher Newman / Epro Technologies

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
> FIX currently only knows the concept of a minimum/maximum order size for a security, tags 562 MinTradeVol and 1140 MaxTradeVol in component <BaseTradingRules>. 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?
