Don't risk more than 2% of your margin per single trade.
What do you mean? does that mean you won't take profit more than 2%?
that's is a good choice if you are a daily trader
you're right, but it's a pretty low presentation. maybe looking at the price, for daily trading, the target above 5% will be better. to be a good trader, try not to be greedy, it makes people stressed out.
