Sometimes when I request data for a RIC, TRTH returns 3 RICs. They are the same for the first 3 or 4 letters, but some have DA, DC after the original RIC and before the ".". So what do they mean? all fields are the same for these RICs.
An example is AEJ.AX. When I requested daily price data for AEJ.AX, there are AEJ.AX, AEJDC.AX, and AEJDA.AX.
