I have been teaching my girlfriend to trade to the point where she would now be interested in her own account. (I am actually a bit concerned about this because I also taught her backgammon and now, unless I want a complete whipping

there is absolutely no point in me playing her)
She would only be able to trade at weekends and evenings (thinking summer. You know... when it is hot and sunny

)
Could BA introduce a tariff for weekend /evening access only?
