how many lots can move the market 1 pip

So, how many lots can move the market for 1 pip? It sure depends on what currency pair.
Now let's say EUR/USD, USD/JPY, XAU/USD, GBP/JPY. I think they are among the most liquid pairs.
And then EUR/NZD and other less liquid pairs.

I think there is no such statistics. There is no such real volume data. It also depends on how many people are involved in the trading. It's a game of bull and bear. The stronger always wins. Sometimes with a little volume a market moves a lot because that time it doesn't face any barriers from the opposite side.
