I guess these 3 alone is enough for you to learn trading already. Now with your question, there are no ways to trade securely, and profitably with 100% win rate because even experts can't achieve that one. We are in a market where everything is unpredictable, and even those who are experts in Technical Analysis can't even predict the market with a high accuracy rate. Also take note that trading is for everyone, but not everyone can make profit thru trading. There will always be losers, and it happens that you're one of them. Try to learn, and research. You lost many times already? I guess you need to take a break first, make a decision whether you want to continue or not.
Sometimes, letting go of your losses is the best way to move on. There are some traders out there who can't recover from their losses, try to trade more, and now they are losing more money. I'm not saying that it will happen to you as well, but also take note that sometimes stopping is the best way to go. Anyway, if you want knowledge, there are many sources online that can help you. It helped me a bit, and got some profit thru these resources online though I'm still not successful in trading, and still experiencing losses.
