Trading is 90% psychology, but
- you can't build confidence without a profitable system.
- you can't have consistent gain without a profitable system.
- you can't be disciplined without a profitable system.
- you can't win without a profitable trading system.
Trading gives you money, in order to to protect your money risk management is paramount.
I have a different view mate. You can build confidence without a profitable system, You need discipline to build a profitable system, You can have a consistent gain without a profitable system but those consistent gains don't happen frequently and it doesn't last too. A profitable trading system when the trader have a plan as well winning strategy.
Confidence is not something you can gain overnight, people often say that you need to fake it until you make it and other silly statements like that, however confidence is built with a good performance over the years and the knowledge you have of your strategy being very good.
So trying to gain confidence and confidence alone is a completely useless exercise, as a trader could have all the confidence on the world, but if their skills are not up to par then soon enough the market will remind them their confidence is unjustified.
