Hi,

I am getting cautious after my first 24 hour time out and wondering what exactly is allowed or not.

1. What is considered scalping - which I understand is not allowed. Is it trading within 5 mins or 15 mins or hour? In a ISA account not CFD

2. Is there an issue with frequently using your whole deposited amount to frequently make short term trades? (I am talking hourly buys/sells not mins)
