Paper trading with large amounts - realistic?

Can paper trading with large amounts of money be used realistically? I'm talking of account sizes of millions.

Would papertrading take in consideration that it would be harder to trade a very large position, compared to a position of just a few number of stocks.


If not, how could you backtest/paper trade very large accounts?

(Just out of curiosity. It's not like I have a very large account... :D )
 
You can't. You can not papertrade realisticly large accounts, and really, what is the point of it?

Unless you would like to know what size moves the market...
 
So if you would have a system that is profitable when you trade "small" account sizes. Say in the 100K+ range. You wouldn't be able to know if the system would lose its "edge" if it was traded with an account size of 1 million or 10 million or more? All other factors being equal, risk mgt and so on...

The only way to find out would be to trade, and thereby possibly lose.

And when trading this big accounts, it is the slippage that eats up the profit. It takes long time to fill large positions. So in that case forex would be the only option.

I'm not talking about daytrading. I suppose position trading would be the only option?
