TickSize in Multi instrument (???)

[xTrader1]

According to the documentation TickSize is the value of 1 tick for the corresponding instrument. I guess that in multi instrument indicator/strategy it is an instrument of DataSeries nr. 0 . How can I get a value of TickSize for instruments in other data series based on other instruments?

xtrader1,

You can check TickSize within a specific BarsInProgress for other series.

if (BarsInProgress == 0) //Primary Series
Print(TickSize);

if (BarsInProgress == 1) //Secondary Series
Print(TickSize);
