Pindex is being traded on Forkdelta:
https://forkdelta.github.io/#!/trade/0xc50948bac01116f246259070ea6084c04649efdf-ETH
Also I can provide some tokens for you (0.25$ each).
that is not official and the price is also very much different with ICO (1 ETH = 800 PDI) so it's better to wait listed on the actually exchange to get the best price
remember ICO pindify just closed a last week, and the platform is not yet operational so this is a great opportunity to collect more PDI Tokens at cheap price
