reasons why traders lose

One builds a trading skills as they trade, those two go hand in hand, I think.

At that time, I lost money because of lack of knowledge and greed, easy to believe so I was slaughtered by these traders. and now it's different, trying to realize and learn to be more mature

Me too. There was a time when I didn't even know to check a forex calendar regularly, I don't know what was I thinking trading on a live account.

i lose much above all when trading with high leverage , tried to bring profit very rapidly but there was no money management or any good trading plan. as a result faced a huge loss. it was my very first past experience.

high leverage means high risk ,
its not true exactly, if there is any risk it is complete with nonsense planning or zero risk management, nothing without it.

True. That's why so many regulators deliberately banned high leverage in many jurisdictions - to protect the traders.

yes , i have read the message that most of the top brokerage cut their leverage ratio due to the corona virus. and so many withdrawal problems i have noticed from that kind of broker.

There have been withdrawal problems too?

withdrawal is a different issue , it completely depends on broker transparencies.

Greed is the main factor of loss in trading and many traders lose their trade because of greediness and they want to become rich quickly but fail.

i would say lack of mental discipline. I used to keep taking trades outside of set ups due to fear of missing out.

If you start trading on a live account - most likely. Spend some time on a demo account until you gain some knowledge, experience and confidence.

Nice one , i like this opinion since i still use demo acc for learning till now, because manage emotion is harder than money management

demo most of the time not works , i means we cant focus on there , its a emotional issue all about.

yeah agree , but after there is no way ignore the importance of demo, because its only the master place for beginners to know what actually forex trading and how to trade in practical.

Demos are really good when you're starting or for testing some strategy but live is totally different environment because it's really money at risk.

Certainly. But that's exactly demo is so necessary - learning in a low-risk environment helps one focus on the learning alone.

Typical mistakes of most traders are the same. What don't you have to do to become a professional and make a stable profit at Forex?
You have chosen a trading strategy, tested it and started trading on a real account. What happens next? At some point it seemed that the market will definitely go up in this place, so you need to open a deal to buy, although the trading system doesn't give any clear signals yet. What happens in the end? Plus, there is one losing order, which might not exist.
If you are familiar with this situation, remember: you have to trade strictly according to the trading system rules. Even if you are 100% sure about something. Any entry into the market must have a justification. If you can't explain why you are going to open an order, you shouldn't do it.
Many traders find it hard to look at a profitable trade. We want to close it immediately and fix the profit. It's dangerous to do it. If the trading strategy assumes 100 pips of profit, and you close the order, barely reaching half, the total balance is broken. As a result, at the end of the month you'll not get profit and you'll get losses in full. It is good if the final result is zero.
Always wait for the end of the trading cycle. The deal should be closed either by stop-loss or take profit. Don't interfere in the process so as not to disturb the balance of the trading system.

right now i have seen the number of newcomers growing very rapidly , may be due to COVID19 and lock down issue, by the way most of them are trading at random and losing , there is anyone in this forum who marked the same point ?

Most of the traders lose their money because of low knowledge about forex. Trading without knowledge can put a trader into the danger.
