Why are you not good at trading?

Because you're engaging in "static indicator trading." You're trying to fight against high-frequency algorithmic robots of 2026 using indicators invented in 1978 like RSI, MACD, and Bollinger Bands.
Why do you like technical indicators? Naked K-line trading is actually because you're lazy. You're too lazy to learn order flow, too lazy to learn how to calculate the order book, too lazy to study statistics, and you've probably only glanced at probability theory for a couple of pages. You try to buy on a golden cross and sell on a death cross, hoping to get rich overnight by 100x leverage.
Market makers are not blind. After a rally, when the price consolidates, your indicator shows a death cross, and volume shrinks. You open a short position, set a stop-loss at a high point, and unsurprisingly, your stop-loss gets triggered at 😂.
Why does the price drop when you buy and rise when you sell? Because your stop-loss is always at the same level. The exchange can see it, market makers can see it. Why not push the price down a bit or smash it to trigger your stop-loss, gaining better liquidity to move to the next price level?
