I can only subscribe to VOD.L; however there are other exchanges like Bats (VODL.BS), Chi-X (VODL.CHI), Turquoise etc. However I can't subscribe to them. So is VOD.L a composite trade on LSE? If not, how can I get subscribe to Euro Bats, Chi-X and Turquoise? Thanks.
It seems that the RIC names you used for other exchanges are not correct. RIC name is case sensitive. The last letter of RIC name for Vodafone Group on other exchange is "l", instead of "L".
For example, BATS (VODl.BS), CHI-X (VODl.CHI), Turquoise(VODl.TQ)
You can use the RIC search tool to search for RIC name.
