You are absolutely correct here. there are many reasons why we experience loss. One of the major reasons which i have experienced is not been able to control your emotions. Trading foreign exchange with emotions usually result to loss. Also lack of discipline like you mentioned above leads to loss too.

The main reason behind the loss is the lack of sufficient strategy.We must have good skills you can get the proper training of the demo account, understand the business and to properly invest in the right capital management time.Also plays a very important role to prevent the loss.

The main reason we lost in trading is that we fail to control our emotions while trading. Apart from that we do not know how to properly take care of MM and also enter the market without making analysis on the market at the time.

greedy is the most common reason for getting loss from forex trading. sometime they see the way of success of trading , but to be successful trader what to do they don't know.

A complete lack of knowledge about what is happening in forex trading markets is a very good reason that sends many traders to losses in their trades in forex. personally, i try to avoid this by constantly reading about forex trading business.

Don't enough analyze befre opening a trade and stick to the plan without letting emotions affect our decisions, and try to follow the trend. When we are greedy, we tend to take higher risk which might be result to lose and when we are afraid sometimes we would close a position too early in loss or eve profit.
