In long-term contract trading, many people will notice a pattern: why do I always make small profits and lose big?

Set a stop loss, and it gets hit immediately. Don't set a stop loss, and the position just gets liquidated at the liquidation price. It looks like it's deliberately locked in.

But honestly, this isn't about luck; the root cause lies in cognition.

You think you're fighting the market, but in reality, you're using a set of trading rules that are inherently unfavorable to retail traders. Your position size, leverage multiple, and liquidation threshold—these data points are all transparent to the exchange. As a result, the situation changes: win once to earn a little, lose once to cut your losses.

Winning ten or twenty times in a row seems stable, but one mistake in operation can wipe out all gains instantly. That's why most people can't escape the fate of long-term losses in contract trading.

The problem isn't that you can't understand market trends, but that your profit and loss structure itself is on the wrong side. To avoid unnecessary detours, the most important thing is to change your trading logic and risk management approach.
