Trading GBPUSD. Trading account base currency?

 
Simple question,

For an EA trading GBPUSD, is there any advantage to having the trading account held in USD over GBP (or vice versa)?

I dont imagine there is but open to.learning.

Not really, as the conversion/exchange is carried out during trading.

The only importance would be when you make a deposit or withdrawal to/from the trading account, and you have to factor in the exchange rate at the time from your own bank account currency.
