I invested $50. Unfortunately I trade in loss. So my account balance is gone down to below $10.
Now my account balance is only below $10. Is it a problem ?
The only problem you have here is you lost about $40 but now this all depends on how you take the loss. As a lesson learned or as something that will hinder you from trading further in the future.
One thing I will surely tell you, is that in trading, you will always lose money along the way especially when you are still a beginner. That why it's necessary to always use money you can afford to lose just in case things don't go well.
