[Forex Trader]

Hi,
I am trying to create an indicator in MetaTrader 4, for which, I'd need to compare the past prices of one currency pair with antother one.
How do I get the past prices of one currency pair in the indicator of another one?

Thanks,
Kash

Thanks. But, this does not allow yo to get Ask/Bid prices. Is there a way to access those?

use MarketInfo function to retrieve bid and ask (parameters MODE_BID and MODE_ASK accordingly)

[Forex Trader]

wouldn't ArrayCopyRates() be better than ArrayCopySeries() ??

ArrayCopyRates was implemented for passing whole history to dll
