Make sure to take profits if the opportunity presents itself. Raise/lower your stop to make a profit if you are trading to prevent risk(especially leverage). Make sure to find a good setup before entering a long or a short. Don't get euphoric and join on emotion. Know when to exit and enter your positions. Losses can get uglier because Chewbacca was confident the price would move higher or lower. Instead, the price action does the opposite, but you're so convinced by your bias that the price will go back into profit you begin to throw all rules out the window and lose discipline as a trader. The next thing you look at your wallet and UH-OH, your negative position becomes a catastrophe.
Now you went from 10% to sitting at a 50% loss and potentially counting or even facing liquidation if not already been. Have a plan, know how much % of your money you are willing to risk before entering, and use a stop loss. You can't always win. It's mathematically impossible, which is why you have to understand how to take a calculated loss and use consistent entries and ratios to result in compound interest. A little example. You enter a long position with $100 and are willing to risk(lose) 2%($2) to return(win) 10% ($10). The risk to reward is a 1:5(ratio), and if you enter at a good level, chances are on your side if the metrics are right. The idea here is that when losing 2%, you have more room for error, and it will take five inconsistencies which are still equivalent to one of your 10% return entries. The idea is consistency and discipline with a plan, execution, a proper risk/reward ratio, and a good setup; the probability is on your side—interest compounds based on your wins. For example, you return separate units of 10%, making a 20% return for two trades. You lose seven trades in a row for a total of 14%. Your ROE is still positive at 6%.
The idea is to stay consistent and compound interest. For example, you should calculate and place a stop loss to cut your position when the asset price you're trading drops 2% to avoid any further loss. You will get faked out by the market when using stop losses, but it's the safest bet. Losing money is not easy, and it takes discipline to move on. Trading is not accessible if you don't understand, don't be discouraged and learn more to help yourself out. End of the day, anything can go right or wrong.
