If you are TRULY treating trading as a business,there is no doubt that you will be sticking to your plan 95% of the time.Because that’s how you scale the business.You don’t scale the business by taking trades that doesn’t make sense or are illogical.You scale by executing trades that are logical and follow your system.
Does this take away the risk involved in it? Does this guarantee you a fixed profit? Taking trading as a business doesn't really change anything or make it more more profitable. It's still more or less of gambling and we should continue to deal with that. How you see trading doesn't matter, what matters is how well you know what you are doing and can handle the outcome. You can Infact take trading as your only hope and still be losing back to back if you don't get it right. Mind you, there is no long term working system and that's why a trader needs to be updated to adjust his strategies time to time.
I can understand what you mean, but I can also understand what Op said. In my understanding, Op is trying to convey that when we stick to a plan it will increase opportunities and of course there will always be risks.
The point I want to convey here lies in the plan, usually successful people can stick to their plans. But will the plan always go according to plan, of course not. In the middle of the road we can get something unwanted, but it is important for us to return to the plan, not change it but we can improve our plan at the beginning based on what we find along the way.
