Losing money in trading is a normal thing but how well are you managing your losses and how many wins do you have ? How many wins do you need to cover your loses?
No matter how professional you are, there is one thing you can’t avoid as a trader, which is loss. You can’t completely avoid that in trading, you will be able to reduce it, but it can’t be avoided. But if you are trading, always make sure you monitor your profits and losses. If your losses are becoming more frequent and they're more than your profits, then there is something wrong, which you need to check. Just stop trading at that time and do more research to know when you are getting things wrong.
Without losses, trader can't be having things in control and can go for the better future in this field as this is important part of the trading but as mentioned we are having few points above in posts like too many trades and time are also important for having better things for having good profit in trade because if we are having no well control system about having entry on right time we still can suffer and having too many trades are also never been ideal.
Staying in touch for the better results and doing research is always helpful for any trader because if he fails to do things then loses can go long and things also can go on negative side which is surely having serious trouble if things are not working as they needed then stop this all and check your mistake and try to avoid them in future which will be also helpful.
