Answered in this post

We aren’t yet allowing cross currency trading yet. Working on it.

Finvasia, 5paisa and samco have these 3 cross-currencies so far.

today jan 01-2020 cross currency enabled by fyers

Have anybody already tested this thing and how it works anyway? I clearly do not get what it means with it but I do not want to intrude you there. I am waiting for some reviews from people who already do work here totally and completely.

Any timelines on when it will be enabled?

How are the volumes for these contracts?
