Market View on GBPCAD

My usual trading system continues to fail, what should I do?

If a trading system built by myself often fails and causes losses, should I abandon this system and replace it with another one? Is there a stable and profitable trading system?

I resigned yesterday, due at the end of the month, I want to do trading full-time, but I don’t know how far this road can go?

Winning ratio and profit-loss ratio, which one do you value more?

For the real-time market, should we keep our original intention or follow the trend?

If you have a bad mentality, does this mean that you are not suitable for trading?
