How to trade EURUSD or GBPUSD in India

[Prayag]

As per RBI press release , cross-currency forex trading is allowed in the pairs that you mentioned.

They trade on NSE and BSE, but they are currently not available on Zerodha -

We haven’t yet enabled trading in cross currency. There are some settlement issues around this. MTM is done based on RBI daily reference rate for USDINR which is announced at 12 noon. But market trades till 7pm, when USDINR could have changed. Risk for us as a brokerage firm.
Also there are trade process issues. Currently only prop trading firms are taking part. Hopefully exchange clarifies on the working and we will be able to offer this.
