For me, risk means growth. If I am taking risk, it means I am taking a step forward towards my growth.
Risk is return for me, bigger the position, more is the reward. I always see the quality pairs and trade according to the events predicted in the economic calendar. You can set risk as per your trading level. You can increase to double figures which is completely dependent on the goals and balance you have.
I believe that risks occur to make you learn from the mistakes and make you well informed for the upcoming uncertainty in the Forex market.
Definitely, half knowledge is lethal. Always work upon your concepts first, then do demo and test your learning there, after few good demo trades go for live trades with small amounts
Agreed, demo accounts are very beneficial for testing the trading environment before starting live trading.
