The broker has some stock indices, the major stock indices are available.
The general maximum leverage is 1:500 and it is also flexible. I stopped bothering about leverage so much when my risk management practice improved. I do not overtrade and also try as much as possible not to enter many positions at a time.
The maximum positions I have opened in recent times is 2 positions and I do not do that often. I was not like this when I started trading, I learnt to follow these rules the hard way.
