When I make a Elektron timeseries data and ask for column "Alternate Close" I do not get any data for any of the symbols.
.tickhist.api.getEndOfDay[`$("RIC";"Trade Date";"Alternate Close";"Last");`00XJEUR.xbo`AAD.AX`ADO.AX`CCP.AX`CCV.AX`ACCP.PA`AIR.PA`GOEG.PA`SOGN.PA`ABA.NZ`AIA.NZ`AIR.NZ`ANZ.NZ;.z.D-100;.z.D;`callback]
q)csv 0: 0!select C:count i by ric,alt_close from data
"ric,alt_close,C"
"00XJEUR.xbo,,71"
"AAD.AX,,73"
"ABA.NZ,,72"
"ACCP.PA,,72"
"ADO.AX,,73"
"AIA.NZ,,72"
"AIR.NZ,,72"
"AIR.PA,,72"
