Like others mentioned. You need to figure out the reason for that first. The strategy you're using is not working? Bad risk/money management? Psychological reasons? ( fear of failure, too much mental or emotional pressure etc ) ... there are many elements that we need to implement before trading successfully. Most people only focus on analyzing charts, news and risk/money management issues. But there is a lot more to it than that.
Once you get the basics that you need to start with. An effective system, and proper management of your trades and account. The rest you can overcome by experience. Most successful traders - if not all - lost tons of money before they started to see first signs of possible success.
My suggestion is to find an online trading course. There are hundreds of them free on Youtube, and you can see from people's comments how it goes, if what they're teaching is effective and works or not. Start from there. Once you get the basics right, and feel that you're ready for more. You can look for someone to teach you or more advanced courses. Free or paid. Those should teach you all the details you need to know to trade and manage your accounts. Then comes the last step, practice on demo. First, to apply what you learn on charts for better understanding. And second, to treat the demo account as if it was real, to get used to trading mindset and master trading Psychologically. Then last step before going live, is to open small real account for practice. Demo trading with real money, if possible. Once you pass this step successfully, you can open your first main trading account and start trading.
What you need to know, in my opinion : Market structure and price action ( not everything about it, only general ideas to understand how price behaves, so once you look at any chart, you would understand what price is doing, instead of seeing random movement ) . A trading strategy ( Price action patterns strategies are the best, but indicators based systems may also be effective ) learn one strategy for day trading and another for scalping, because probably you'll need both. The impact of news and how to manage it. Then risk/account management.
One last thing to keep in mind, there are many markets to trade. And they're all different even if they look the same or similar on charts. You need to find a market that you understand better than others, and feel more comfortable in trading that market. And within that market, you also may want to find a specific asset or few ones to master. For example, couple of Forex pairs, instead of trading all. I know successful Forex traders for example, who trade only one currency pair. Because they understand that one pair more than all others.
And to be honest, forums are not to learn trading. Forums are for social communication with other traders and exchange/share experience/opinions, and getting specific needs ( information - tools etc ) but not to learn trading. Because each and every trader got their own trading style that may not work for you. Being experienced in trading doesn't mean being experienced in teaching. You need to find someone who's not only willing to teach you, but most important, someone with teaching skills and experience in teaching. And that's difficult to find in forums. Not saying it's impossible. But it may take lots of time and effort that you could use better going to a better educational source to teach you personally and professionally.
