Some newbie questions regarding Forex Volumes

Hello,

I am trying to trade forex futures and want to learn more about the market. I have some questions regarding volumes and exchanges.

  1. Does volumes matter in forex (Indian markets) ? do they have any substantial impact on price action similar to stock/index futures. I have read that volumes do not matter much in forex as the transactions are huge in forex (worldwide).
  2. There are two exchanges in India currently, CDS and BCD, one having more liquidity than the other (based on my observation). Based on my first question, say if I am placing a reasonably big order, let’s say 100-200 lots in both, does it differently impact the price behavior.

Can someone please answer

Thanks
