Hi there, I am trying to run the following:

INPUT:

    parfor i=1:1:5
      data(i)=IBMatlab('action','query','symbol','EUR','localSymbol', 'EUR.USD', 'secType', 'cash', 'exchange', 'idealpro');
      price(i)=data(1,i).bidPrice(1,1);  
    end

OUTPUT:

??? Error: The variable data in a parfor cannot be classified. See Parallel for Loops in MATLAB, "Overview".

Any help anybody? WHEN I USE NORMAL FOR LOOP IT WORKS.

The error is only coming from the line...

price(i)=data(1,i).bidPrice(1,1);

You need to ensure that you're indexing 'data' in a consistent manner inside the PARFOR loop. It should work to make both references either 'data(1,i)' or 'data(i)'.
