For the first tip you mentioned that choose a broker who allow day trading, as far as I know all brokers allow day trading, right? do you mean there are brokers which don't allow day trading? can you list them?
For the second tip,be prepare to trade anytime, to be frank, in my opinion, forex trading has its the best time to trade, not all time are suitable for us to trade. we can get more profit if we can grasp the best time to trade in forex.
