Ask yourself do you actually treat trading as a business? Or are you convincing yourself that you are treating it as a business.For most of the people,treating trading as a business doesn’t clicks.Because if you go through your trades and cross-check them,you will begin to realize that for most of the trades you don’t stick to your plan.
You can be a master in trading but the fact that you tend to treat it as business is what I don't buy into cause in business it's different in the sense that it's not on most basis that your business stick to the plans you have budgeted,this is why everything is controlled by a change and in the logical sense we all know trading is prone to much risks factors so applying it in business can actually rupture alot leading to uncontrollably losses.
