My strategy is 1/3 so I risk 1% of my balance to profit 3%
If i lose twice that means im only 2 % down
i dont do more than 2 trades per day as overtrading leads on lost
my 1st live trading was a profit as I try to maintain the discipline and risk menagment
In trading, risk management is very important. The amount used to risk for your profit should be lesser to what you are aiming for so that even if you lose that trade, it won't affect your account size and discourage you to go for a potential winning trade. Just as you said 1/3 ratio is cool.
However, emotion is important to be put under check. Trading demo is not same with real trading because of the real money involved.
We also have to know it is very risky trading forex or CFDS. They are highly volatile and you can lose your capital at a go if you don't protect your account by using SL.
