Trading large lot quantities into lower volume pairs

Hey guys,

Just wondering if anyone knows how to find daily volume on currency pairs and then how to figure if a given number of lots will be be difficult to liquidate in a given market at a given time.

For example, I could realistically trade 1,000+ standard lots of USDZAR on a given trade.

Is that too much volume for a smaller pair like this or am I over estimating the position size relative to the market?

Anybody?

SORRY dude. you can tell I don't trade it. USDZAR not ZARUSD.
so long as you don't exceed $1-$3m at a time notional you're fine and if over split it across time.
